ACTION FORM PROCEEDING: Utility Committee AGENDA ITEM DEPARTMENT OF ORIGIN: Public Services DATE SUBMITTED: June 2, 2011 PREPARED BY: Scott D. Koenig, P.E., Public Services Manager SUBJECT: Universal Recycling Grants – Recycling Services Reimbursement Agreement REFERENCE: N/A RELATED PROJECT: N/A APPROVALS: City Manager, City Controller EXHIBITS: Attachment A – Recycling Services Reimbursment Agreement – Contract # 11-URG025 EXPENDITURE REQUIRED: $101,151.00.

The City of Dover will be eligible for reimbursement up to $101,151.00 for work and/or services identified in the agreement. BACKGROUND AND ANALYSIS In June 2010, the State of Delaware passed legislation which established Universal Recycling in Delaware. This legislation requires the the implementation of comprehensive residential and commercial recycling programs by municipalities and waste haulers. It also established the Delaware Recycling Fund and the Recycling Grants and Low-Interest Program to defray the costs of implementation, and funds, with funding derived by the conversion of the former bottle deposit to a Recycling Fee on beverage containers. In January 2011, the City of Dover submitted a series of grant applications related to the implementation of a comprehensive recycling program. In April 2011, the City of Dover was informed that we have received Universal Recycling Grant funding in the amount of $101,151 as follows: 1) Public Information & Education for Customers - $ 15,000.00 2) “Schedule Change” Flyers Reimbursment - $ 3,115.00 3) Curbside Recycling Container Labels (Qty. = 15,250) - $ 2,798.00 4) Purchase of 1,782 wheeled recycling carts - $ 80,238.00 Total: $ 101,151.00 Staff is requesting authorization to execute the reimbursement agreement labeled as Attachment A and begin the work associated with the agreement. The City of Dover expended funds in FY-2011 for the purchase of wheeled recycling containers, curbside recycling container labels and “Schedule Change” flyers. All of these expenses related to the implementation of the curbside program and will be eligible for reimbursement once the agreement has been signed. These expenses are part of the funds identified in 2), 3) and 4) listed above.

Hedged transactions accounted for 49,920 MWhs or 92% of this volume (95% of forecasted load) at a cost of $3.48 million. Spot Market purchases resulted in a PJM charge of $388 thousand (a $372 thousand charge in the Day Ahead market and a $16 thousand charge in the Real Time market). Other PJM related charges accounted for an additional cost of $1.41 million, inclusive of all load related fees. The April Energy Only Unit Cost, excluding capacity obligations and credits, was $2.65/MWh favorable compared to the budgeted value of $83.85/MWh. On January 24, 2011, the City of Dover reviewed and approved Pace’s and NAES’ submittal of a revised budget for Dover’s FY2010-11 (the “Reset Budget”). The purpose of this Reset Budget was to provide a mid-year update as to the anticipated cost-of-service for FY2010-11. Dover’s projected all in Cost of Service for FY2010-11 is $88.64/MWh, or $1.88/MWh favorable as compared to the Reset Budget1. Generation and Asset Management For the month of April the McKee Run and Van Sant units were not dispatched into the PJM market. A relatively low average for on-peak LMPs during the month demonstrated that the PJM system did not generally require support from peaking units. The McKee units started a planned outage on March 28 that will last until May23. The budget did not project any generation for this month. Emissions Allowance Management 1 The projected all in Cost of Service is based on YTD actual results for 10 months and 2 months of projected costs. The Reset Budget was reviewed and approved by City of Dover. 2

Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet their 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover their 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Dover has the appropriate number of allowances were set aside for retirement (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NO x seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. (3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. 3

Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $35,274 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $4/ton, 3,976 post-CAIR SO2 allowances trading at $2.50/ton, 73 NOx annual allowances trading at $157.50/ton, and 54 NOx seasonal allowances trading at $20/ton.

The facility has now gone 198 days without an OSHA recordable accident and 198 consecutive days without a lost time reportable accident. There were zero Environmental Notices of Violations issued. There were no near miss events. All three Units at McKee Run were in a planned outage. There were no opportunities to generate during the month and no units were dispatched for PJM. Monthly Budget Variance - The actual expenses attributable to O&M of the two sites for the month of April were $413,166. The expenses were $23,599 or 5.40% under the approved budget of $436,765. The principal reason for the favorable variance is due to delayed timing of payments for environmental expenses, home office labor and boiler systems that will occur later in the year. 2 Approximately 10 tons of NOx emissions resulted from the February 2010 McKee Run testing associated with the Pollution Remediation project and the June 2010 emission testing project. 3 The EPA reallocated 2 additional seasonal NOx allowances into the McKee Run 2011 account. 4

Risk Management Summary Forward PJM power prices decreased slightly since the last reporting period. Prices decreased as forecasts called for mild temperatures across most parts of the country. Forward Dover Zone power prices for FY 2010-11 increased by $0.13/MWh (an increase of 0.25%) since the last reporting period while FY 2011-2012, FY 2012-2013, FY 2013-2014, and FY 2014-2015 all changed by approximately -$0.49/MWh to $0.02/MWh (representing a range of -0.91% decrease and a 0.25% increase, respectively) compared with the last reporting period.

2.2 – VARIANCE ANALYSIS Power Supply  Power Supply realized a favorable $43 thousand variance compared to the budget. This favorable variance was primarily due to the timing of Dover’s options purchase and payment of the associated premium. During FY2009-10 the City of Dover purchased Options as insurance to protect Dover from incremental energy cost exposure. The current City of Dover power supply and generation budget indicates that 100% of this purchase was expensed as a Power Supply Cost in the FY2009-10 period; however the FY2010-11 budget accrues this expense monthly.  PJM Charges for Load experienced a negative $52 thousand variance relative to the monthly budget. This variance was driven by Dover’s open position, which was 69% higher than budget. A larger volume of open positions, coupled with higher than projected PJM energy open prices, resulted in a total Open Position cost that was $116 thousand greater than budget. Additional factors contributing to the unfavorable variance included i) a $42 thousand unfavorable variance in PJM Ancillary charges and ii) a $27 thousand unfavorable variance in Transmission Rights Credits. Offsetting these unfavorable variances were a $115 thousand favorable variances in Load Following and a $23 thousand favorable variance in Basis costs.  For the month the City realized a $10 thousand unfavorable net variance between Power Supply (fixed positions) and PJM Charges for Load (open positions, transmission, etc.). The change in volume resulted in an unfavorable $141 thousand variance, and the change in price resulted in a favorable $131 thousand variance. Hence, all of the unfavorable variance can be attributed to volumn changes.  The Power Supply Management variance is merely an estimate at this point. Generation  Plant O&M reported a favorable variance of $24 thousand compared to the revised monthly O&M reset Budget of $437 thousand (the overall reset plant budget for FY 2010-11 was approved by the City Council on March, 2011). The timing of environmental, home office labor and boiler systems expenses created the favorable variance. These expenses will occur at a later date. 8

3.0 – ENERGY MANAGEMENT 3.1 – PURCHASED POWER Management Highlights  Dover’s April load was 54,359 MWh, which was 3.4% above the weather normalized load of 52,554 MWh. Hedge volumes accounted for 92% of actual load for the month.  The April All In Unit Energy cost (excluding capacity) of $81.20 per MWh is $2.65 per MWh lower than the monthly budget.

This expense will now fall under the plant’s utility costs and be paid and budgeted for by the station. 16

Gas Transportation Purchased City of Dover decided not to renew agreements with the Eastern Shore Natural Gas Pipeline (“ESNG”) and TransCo to provide firm natural gas deliveries to the McKee Run and Van Sant stations. The City of Dover previously notified ESNG and TransCo of its intent to terminate these existing firm capacity agreements and, as a result, the City no longer pays firm demand charges or adjustments.

3.3 – EMISSIONS AND ALLOWANCE MANAGEMENT Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet their 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover their 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Dover has the appropriate number of allowances were set aside for retirement (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NO x seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. 19

(3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $35,274 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $4/ton, 3,976 post-CAIR SO2 allowances trading at $2.50/ton, 73 NOx annual allowances trading at $157.50/ton, and 54 NOx seasonal allowances trading at $20/ton. SO2 SO2 allowances continue to lose value as the likely release of final version of the Environmental Protection Agency’s (EPA) Clean Air Transport Rule (Transport Rule) approaches. Allowances have steadily declined since the lead up to the issuance of the proposed Transport Rule in July 2010 (see Figure 1 – SO2 Prices 2010 - 2011). Should the final Transport Rule adopt similar rules as the proposed version, current vintage SO2 allowances will not be eligible for compliance under the new trading program. Figure 1 – SO2 Prices 2010 - 2011 SO2 Allowance Prices (2010 / 2011) $100.00 $80.00 $60.00 $/ton $40.00 $20.00 $0.00 1/4/2010 2/4/2010 3/4/2010 4/4/2010 5/4/2010 6/4/2010 7/4/2010 8/4/2010 9/4/2010 10/4/2010 11/4/2010 12/4/2010 1/4/2011 2/4/2011 3/4/2011 4/4/2011 5/4/2011 2009 (pre-CAIR) 2010/2011 (post-CAIR) NOx NOX annual allowance prices have steadily declined through most of 2011, continuing their slide from 2010. The late February and early March drop in allowance prices is attributable to the March 1st compliance deadline for 2010 emissions (See Figure 2 – NOX annual prices 2011). Current vintage NOX annual allowances are not expected to be eligible for compliance in the new trading program established by the Transport Rule. Prices between now and the compliance date 20

for 2011 could be volatile, particularly if the high summer temperatures require units to run at levels similar to summer 2010. NOX seasonal prices have remained consistently in the $20 - $30/ton range for all of 2011 (See Figure 3 – NOX seasonal prices 2011.) As with NOX annual and SO2 allowances, new trading rules under the Transport Rule are unlikely to allow current vintage NOX seasonal allowances to qualify for compliance. Figure 2 – NOX annual prices 2011 NOX Annual Allowance Prices 2011 $400.00 $350.00 $300.00 $250.00 $/ton $200.00 $150.00 $100.00 $50.00 $0.00 Figure 3 – NOX seasonal prices 2011 NOX Seasonal Allowance Prices 2011 $35.00 $30.00 $25.00 $20.00 $/ton $15.00 $10.00 $5.00 $0.00 21

SO2 and NOx Outlook Market participants continue to sit largely idle, awaiting some level of regulatory certainty from EPA. The final Transport Rule, setting new emissions trading rules, is expected to be released in June or July this year. The expectation is that there will be new allowances for SO2 and NOX emissions, leaving little value for the existing bank of allowances beyond this year’s compliance requirements. It is difficult to estimate what the future compliance costs for SO2 and NOX emissions will be under new trading rules with a number of variables still unknown - the release of the final Transport Rule should provide some clarity. The method and extent of allowances allocated directly to units, pollution caps, and flexibility in trading will all impact the ultimate compliance costs for regulated units. To date, three separate allowance allocation methodologies have been proposed, which all give Dover varying levels of coverage (See Figure 4 – Three Different Allowance Allocations Proposed by EPA).

RGGI and Federal Carbon Outlook RGGI allowance prices continue to price at very low levels, as the market is substantially over supplied, forcing prices to levels at or near the statutory price floor (see Figure 5 – RGGI Allowance Prices). Figure 5 – RGGI Allowance Prices RGGI Prices 2011 $1.95 $1.90 $/ton $1.85 $1.80 1/3/2011 2/3/2011 3/3/2011 4/3/2011 5/3/2011 Based on projected generation and emissions, Dover is projected to have an excess of 150,000 allowances through 2013 with a market value at current prices of $283,000. Despite the high level of uncertainty surrounding carbon legislation, Pace Global continues to anticipate an eventual price on carbon at a national level, although the timing, method, and scope of coverage are all substantially unknown at this time. Pace Global expects carbon regulation to evolve through three main drivers: 1. Legislation; 2. EPA regulation under their existing authority; and 3. Linkage of regional and state initiatives. The three carbon pricing drivers will likely develop in parallel and, at times, in concert with one another. Through the three drivers, Pace Global anticipates a national price on carbon emissions via a market based system, or combination of systems, beginning sometime between 2015 and 2018. There have been a number of proposed measures in Congress that would temporarily or permanently negate EPA’s authority to regulate GHGs. Attempts to cut EPA’s regulatory funding for GHG programs in the FY 2011 federal budget were unsuccessful; however the fight will likely continue as Congress debates the FY2012 federal budget. Additionally, bills to permanently repeal EPA’s regulatory authority appear to have stalled for the time being, with insufficient support in the Senate and threats of Presidential veto from the Administration. 23

The implementation of the data substitution rules were caused by performing a linearity test outside the grace period. NAES ESS was able to provide assistance in reducing the NOx emissions from 137 tons to 119 tons since the October report. A petition to the EPA was sent out in February that would result in a reduction in reported emissions. The EPA has given preliminary approval to the petition request although it is not official until the plant receives a signed EPA approval. Until the issue is resolved, the EPA has locked the annual account and no allowances will be deducted until that time. Note# - 53 tons were purchased to help compensate for the shortage in seasonal NOx allowances. Note## - 22 tons were purchased to help compensate for the shortage in annual NOx allowances.

The actual expenses for April were $413,166 for a favorable variance of $23,599 or ≈ 5.40%. The variance was due to the following: PERSONNEL EXPENSES - Labor, overtime, and burdens accounted for a total monthly unfavorable variance of $3,199. A lower overtime expense due to scheduling changes and flex time usage was offset by higher than budgeted straight time expenses due to the flex leave payout of a recently terminated (resignation) employee. An increase in burdens was also due to the employee flex leave payout. MATERIALS AND SUPPLIES EXPENSES- Lower expenses in Office Supplies and Security/Safety Materials accounted for a favorable variance of $2,745 for the month of April. ADMINISTRATIVE EXPENSES – During the month of April, a favorable variance of $24,053 was realized due to lower expenses in Environmental Expenses, Home Office Labor, Auxiliary Systems, Boiler Systems, and Combustion Turbine Maintenance. The current budget forecast for the current fiscal year is $6,159,886 expensed versus an adjusted budget of $6,163,315 thereby realizing a 99.94%.expense rate. 30

III. GLOSSARY Energy Only Unit Cost ("EOU") accounts for the wholesale energy costs excluding capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. The AIE includes the costs from settling the hedged or forward transactions; the energy bought on the ISO (Independent System Operator or PJM) day-ahead to cover the open position (un-hedged); load following costs associated with balancing the actual load in the ISO real-time market; energy management service related fees; the ISO transmission charges and credits to load serving entities; the ISO ancillary services charges such as generation regulation, spinning reserve, and reactive power; and the ISO administrative charges and cost of service recovery fees. All In Cost of Service ("AICS") accounts for the net cost of wholesale power to the City of Dover Electric Utility. The AICS starts with the AIE and adds the costs or credits from capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. Black Start is a generating ancillary service that is the process of restoring a generating plant to service without the support of an external power supply to power auxiliary equipment needed for start up operations. Capacity UCAP Obligated Purchased is the obligation and payment by all load serving entities in PJM including Dover for the Unforced Capacity (UCAP) requirement from PJM that satisfies the PJM reserve requirements. Generation Capacity Credit: is the credit provided to generators for supply capacity to the system. The price is determined by the PJM Reliability Pricing Market auction process that includes three auctions for each capacity year. Generation Production Margin accounts for the variable margin excluding variable O&M and emissions. The Generation Production Margin is calculated by taking the PJM revenues credited to the plant including any balancing charges or credits less the fuel costs. Generation Production Margin includes both “Economic and reliability dispatch” and “Testing.” Economic and reliability dispatch equals the margin achieved when Dover’s generating plants are dispatched by PJM for either economic dispatch (the system energy price is greater than the Dover bid price) or reliability dispatch whereby PJM pays the generating cost of the plants for the hours the plant is run to support the system. Generation Testing equals the Generation Production Margin associated with testing. This is usually expected to be a negative margin because the plant is potentially being dispatched / run when energy prices do not cover its costs. Non-Production Revenue equals the credits from PJM to Dover for Generation Capacity Credit, the Black Start Revenue and the sales by Dover of Emission Allowances. 42

Hedged transactions accounted for 48,155 MWhs or 84% of this volume (85% of forecasted load) at a cost of $3.72 million. Spot Market purchases resulted in a PJM charge of $453 thousand (a $506 thousand charge in the Day Ahead market and a $53 thousand credit in the Real Time market). Other PJM related charges accounted for an additional cost of $1.41 million, inclusive of all load related fees. The March Energy Only Unit Cost, excluding capacity obligations and credits, was $3.91/MWh favorable compared to the budgeted value of $85.66/MWh. On January 24, 2011, the City of Dover reviewed and approved Pace’s and NAES’ submittal of a revised budget for Dover’s FY2010-11 (the “Reset Budget”). The purpose of this Reset Budget was to provide a mid-year update as to the anticipated cost-of- service for the FY2010-11. Dover’s projected all in Cost of Service for FY2010-2011 is $88.78/MWh, or $1.88/MWh favorable as compared to the Reset Budget1. Generation and Asset Management For the month of March the McKee Run and Van Sant units were not dispatched into the PJM market. A relatively low average for on-peak LMPs during the month demonstrated that the PJM system did not generally require support from peaking units. Van Sant unit performed a planned outage from March 14 to 24 and the Units at McKee started a planned outage on March 28 that will last until May23. After several testing attempts, Van San unit successfully completed the annual Black Start Test. The budget did not project generation for this month. Emissions Allowance Management 1 The projected all in Cost of Service is based on YTD actual results for 8 months and 4 months of projected costs. The Reset Budget was reviewed and approved by City of Dover. 2

Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet its 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover its 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Pace has set aside a projected number of allowances to handle estimated dispatch events for the year (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NO x seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. (3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. 3

Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $44,918 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $6/ton, 3976 post-CAIR SO2 allowances trading at $4/ton, 52 NOx annual allowances trading at $170/ton, and 52 NOx seasonal allowances trading at $20/ton.

The facility has now gone 168 days without an OSHA recordable accident and 168 consecutive days without a lost time reportable accident. There were zero Environmental Notices of Violations issued. There were no near miss events. There were no opportunities to generate during the month and no units were dispatched for PJM. Planned outage on Unit 11 was completed on March 24. A black start test was successfully completed on that unit during the month. McKee Run Units 1, 2 and 3 started a planned outage on March 28. Monthly Budget Variance - The actual expenses attributable to O&M of the two sites for the month of March were $414,919. The expenses were $47,908 or 13.05% over the approved budget of $367,0113. The principal reason for the negative variance is due to timing of insurance expenses and higher than budgeted expenses in electric, heating oil and gas,and boiler systems repairs. 2 Approximately 10 tons of NOx emissions resulted from the February 2010 McKee Run testing associated with the Pollution Remediation project and the June 2010 emission testing project. 3 NAES will reflect the reset monthly and year-to-date financial data starting on April 2011 Monthly Report. 4

Risk Management Summary Forward PJM power prices rose slightly since the last reporting period. Prices increased largely due to more moderate temperatures sweeping across much of the country combined with more bullish storage numbers. Forward Dover Zone power prices for FY 2010-11 increased by $0.16/MWh (an increase of 0.31%) since the last reporting period while FY 2011-2012, FY 2012-2013, FY 2013-2014, and FY 2014-2015 all increased by approximately $0.02/MWh to $0.47/MWh (representing a range of 0.03% increase and a 0.78% increase, respectively) compared with the last reporting period.

2.2 – VARIANCE ANALYSIS Power Supply  Power Supply realized a favorable $46 thousand variance compared to the budget. This favorable variance was primarily due to the timing of Dover’s options purchase and payment of the associated premium. During FY2009-10 the City of Dover purchased Options as insurance to protect Dover from incremental energy cost exposure. The current City of Dover power supply and generation budget indicates that 100% of this purchase was expensed as a Power Supply Cost in the FY2009-10 period; however the FY2010-11 budget accrues this expense monthly.  PJM Charges for Load experienced a positive $83 thousand variance relative to the monthly budget. This variance was driven by Dover’s load following position, which was $194 thousand favorable compared to budget. In addition, Dover realized a $17 thousand favorable variance in Basis costs. Offsetting these favorable variances included i) a $96 thousand unfavorable variance in Open Position, which was 13% higher than budget; ii) a $16 thousand unfavorable variance in Transmission Rights Credits; and iii) a $10 thousand unfavorable variance in PJM Ancillary charges.  For the month the City realized a $129 thousand favorable net variance between Power Supply (fixed positions) and PJM Charges for Load (open positions, transmission, etc.). The change in volume resulted in an unfavorable $85 thousand variance, and the change in price resulted in a favorable $214 thousand variance. Hence, all of the favorable variance can be attributed to pricing changes.  The Power Supply Management variance is merely an estimate at this point. Generation  Plant O&M reported an unfavorable variance of $21 thousand compared to the monthly O&M reset Budget of $434 thousand ($48 unfavorable variance compared to the original budget of $367 thousand). Higher than projected utilities and boiler repair cost; and the timing of insurance expenses created the unfavorable variance. 8

3.0 – ENERGY MANAGEMENT 3.1 – PURCHASED POWER Management Highlights  Dover’s March load was 57,414 MWh, which was 1.9% above the weather normalized load of 56,334 MWh. Hedge volumes accounted for 84% of actual load for the month.  The March All In Unit Energy cost (excluding capacity) of $81.75 per MWh is $3.91 per MWh lower than the monthly budget.

Gas Transportation Purchased City of Dover decided not to renew agreements with the Eastern Shore Natural Gas Pipeline (“ESNG”) and TransCo to provide firm natural gas deliveries to the McKee Run and Van Sant stations. The City of Dover previously notified ESNG and TransCo of its intent to terminate these existing firm capacity agreements and, as a result, the City no longer pays firm demand charges or adjustments. ESNG FT Demand Charge $ 0 TransCo FT Demand Charge $ 0 Total Purchases $ 0 Other Gas Purchases Commodity and transportation imbalances on Eastern Shore Pipeline for the month resulted in no charge. The components of this charge are summarized as follows: Eastern Shore Transport and Imbalance Charges Imbalance/Dth Estimated Cost/Dth Estimated Total Cost 0 $0.00 $0.00 Transport Volume/Dth $/Dth Total Cost Firm/IT 0 $0.00 $0.00 Net Charge $0.00 17

3.3 – EMISSIONS AND ALLOWANCE MANAGEMENT Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet their 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover its 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Pace has set aside a projected number of allowances to handle the estimated dispatch events for the year (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NO x seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. (3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. 19

Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $44,918 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $6/ton, 3976 post-CAIR SO2 allowances trading at $4/ton, 52 NOx annual allowances trading at $170/ton, and 52 NOx seasonal allowances trading at $20/ton. SO2 SO2 allowances continue to have little value in the market, trading below $10/ton for all of 2011 (see Figure 1 – SO2 Prices since Last Monthly Report). The major brokerage houses are reporting very few transactions in the market. Market participants continue to wait for final rules regulating the markets, and even then the value of existing SO2 allowances are unlikely to return to levels we saw two and three years ago. Figure 1 – SO2 Prices since Last Monthly Report SO2 Allowance Prices (Mar / Apr) $8.00 $7.00 $6.00 $5.00 $4.00 $3.00 $2.00 $1.00 $0.00 17 Mar 2011 19 Mar 2011 21 Mar 2011 23 Mar 2011 25 Mar 2011 27 Mar 2011 29 Mar 2011 31 Mar 2011 02 Apr 2011 04 Apr 2011 06 Apr 2011 08 Apr 2011 10 Apr 2011 12 Apr 2011 14 Apr 2011 16 Apr 2011 18 Apr 2011 20 Apr 2011 2009 (pre-CAIR) 2010/2011 (post-CAIR) NOx NOX annual allowance prices have continued to decline after the March 1st compliance deadline for 2010 emissions, trading most recently at near record lows (See Figure 2 – NOX annual prices since last monthly report.) With the increasing likelihood that existing allowances will not carry over into the new regulatory program, NOX allowance prices could be volatile during the remainder of 2011, particularly if we see a spike in emissions like we did during the summer of 2010. NOX seasonal prices lost $10/ton trading most recently at $20/ton (See Figure 3 – NOX seasonal prices since last monthly report.) 20

The final Transport Rule, setting new emissions trading rules, is expected to be released in June or July this year. The expectation is that there will be new allowances for SO2 and NOX emissions, leaving little value for the existing bank of allowances beyond this year. If the existing bank is to retain any value beyond this year, EPA would have to elect to take a significantly different path than they did in 21

the proposed rule – which is not expected – or Congress would have to pass legislation regulating the markets. At this point, there does not seem to be a tremendous amount of momentum behind legislation in this arena, although that could change quickly depending on industry and other stakeholder reaction after the issuance of the final Transport Rule. RGGI and Federal Carbon Outlook RGGI allowance prices continue to trade at very low amounts, as the market is substantially over supplied, forcing prices to levels at or near the statutory price floor (see Figure 4 – RGGI Allowance Prices). Figure 4 – RGGI Allowance Prices RGGI Prices (Mar / Apr) $1.95 $1.90 $1.85 3/17/2011 3/19/2011 3/21/2011 3/23/2011 3/25/2011 3/27/2011 3/29/2011 3/31/2011 4/2/2011 4/4/2011 4/6/2011 4/8/2011 4/10/2011 4/12/2011 4/14/2011 4/16/2011 4/18/2011 4/20/2011 Based on projected generation and emissions, Dover is projected to have an excess of 145,000 allowances through 2013 with a market value at current prices of $275,500. The first true-up period for RGGI will take place on December 31st, 2011. Despite the high level of uncertainty surrounding carbon legislation, Pace Global continues to anticipate an eventual price on carbon at a national level, although the timing, method, and scope of coverage are all substantially unknown at this time. Pace Global expects carbon regulation to evolve through three main drivers: 1. Legislation; 2. EPA regulation under their existing authority; and 3. Linkage of regional and state initiatives. The three carbon pricing drivers will likely develop in parallel and, at times, in concert with one another. Through the three drivers, Pace Global anticipates a national price on carbon emissions via a market based system, or combination of systems, beginning sometime between 2015 and 2018. 22

There have been a number of proposed measures in Congress that would temporarily or permanently negate EPA’s authority to regulate GHGs. Attempts to cut EPA’s regulatory funding for GHG programs in the FY 2011 federal budget were unsuccessful; however the fight will likely continue as Congress debates the FY2012 federal budget. Additionally, bills to permanently repeal EPA’s regulatory authority appear to have stalled for the time being, with insufficient support in the Senate and threats of Presidential veto from the Administration. 23

The implementation of the data substitution rules were caused by performing a linearity test outside the grace period. NAES ESS was able to provide assistance in reducing the NOx emissions from 137 tons to 119 tons since the October report. A petition to the EPA was sent out in February that would result in a reduction in reported emissions. The EPA has given preliminary approval to the petition request although it is not official until the plant receives a signed EPA approval. Until the issue is resolved, the EPA has locked the annual account and no allowances will be deducted until that time. Note# - 53 tons were purchased to help compensate for the shortage in seasonal NOx allowances. Note## - 22 tons were purchased to help compensate for the shortage in annual NOx allowances. Note###- 2 tons were reallocated by the EPA to the McKee Run 2011 account.

The actual expenses for March were $414,919 for an unfavorable variance of ($47,908) or approximately 13.05%. The variance was due to the following: PERSONNEL EXPENSES – Straight Time Labor and burdens accounted for a total unfavorable variance of $3,547. MATERIALS AND SUPPLIES EXPENSES – An unfavorable variance of $6,696 was realized due to spending in Office Supplies, Computer Software and Safety Supplies for the month. ADMINISTRATIVE EXPENSES - Higher than budgeted expenses in Insurance, Electric, Heating Oil / Gas, Contractual Services, Environmental Expenses, Home Office Labor, and Boiler Systems contributed to an unfavorable variance of $37,665. The budget is currently forecast to finish this fiscal year at $6,124,375 expensed versus $6,163,315 budgeted (reset) thereby realizing a 99.55% expenditure rate. Note: The budget has now been reset by the City of Dover Financial Department. Future reports will reflect the reset monthly and year-to-date numbers. 30

3.0 Operations Unit Operations / Outages / Trips No units were dispatched by PJM for the month of March. On March 9, during a Black Start test, Unit 11 tripped after being on line for four minutes due to a bad PLC module in the combustion monitoring protection circuitry. The module was replaced and several days later, the unit successfully completed the annual Black Start Test. VanSant was in a Planned outage from March 14 to 24 for an annual inspection and for testing of the CTs, PTs and DC Control Circuitry. The Units at McKee started a planned outage on March 28 that will last until May23. The scope of work on Units 1 & 2 includes the installation of upgrades to the burner control system, condenser cleaning and inspections of the steam turbines. The work scope on Unit 3 includes the installation of gas valves on each burner deck, the installation of a new expansion joint in the ductwork above the air heater and an annual inspection.

Ron McNair, Rick Barber and Aaron Jester participated in the drill for training purposes. The simulation drill had the operators ask and answer some questions on system operation. Participation in the drill earned each operator simulation credits that go towards maintaining their PJM System Operator certification. The PJM Generation Systems Operator exam study groups continue to meet during the month with different study topics. The study group focuses on subjects that are covered on the exam. This month’s topics were Market Monitoring, PJM Day Ahead Market, Generation outages and eDART. Ron McNair and Rick Barber attended the PJM 2011 PJM System Operator Seminar in the third week of May. This seminar provides updated information on PJM, NERC, and FERC regulations and standards that are coming in the future. It also provides credits to the individual that go toward retaining his PJM Gen Ops Certification. On March 29, the plant conducted an Emergency Response Deployment Drill. The scenario was a fuel oil leak by the transfer pump area. The object was to contain the oil spill with booms (rope was used in place of actual booms) and to keep oil from going to the outfalls or the lake. Actual contacts were made to plant personnel and to clean-up crews to simulate response time. 37

III. GLOSSARY Energy Only Unit Cost ("EOU") accounts for the wholesale energy costs excluding capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. The AIE includes the costs from settling the hedged or forward transactions; the energy bought on the ISO (Independent System Operator or PJM) day-ahead to cover the open position (un-hedged); load following costs associated with balancing the actual load in the ISO real-time market; energy management service related fees; the ISO transmission charges and credits to load serving entities; the ISO ancillary services charges such as generation regulation, spinning reserve, and reactive power; and the ISO administrative charges and cost of service recovery fees. All In Cost of Service ("AICS") accounts for the net cost of wholesale power to the City of Dover Electric Utility. The AICS starts with the AIE and adds the costs or credits from capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. Black Start is a generating ancillary service that is the process of restoring a generating plant to service without the support of an external power supply to power auxiliary equipment needed for start up operations. Capacity UCAP Obligated Purchased is the obligation and payment by all load serving entities in PJM including Dover for the Unforced Capacity (UCAP) requirement from PJM that satisfies the PJM reserve requirements. Generation Capacity Credit: is the credit provided to generators for supply capacity to the system. The price is determined by the PJM Reliability Pricing Market auction process that includes three auctions for each capacity year. Generation Production Margin accounts for the variable margin excluding variable O&M and emissions. The Generation Production Margin is calculated by taking the PJM revenues credited to the plant including any balancing charges or credits less the fuel costs. Generation Production Margin includes both “Economic and reliability dispatch” and “Testing.” Economic and reliability dispatch equals the margin achieved when Dover’s generating plants are dispatched by PJM for either economic dispatch (the system energy price is greater than the Dover bid price) or reliability dispatch whereby PJM pays the generating cost of the plants for the hours the plant is run to support the system. Generation Testing equals the Generation Production Margin associated with testing. This is usually expected to be a negative margin because the plant is potentially being dispatched / run when energy prices do not cover its costs. Non-Production Revenue equals the credits from PJM to Dover for Generation Capacity Credit, the Black Start Revenue and the sales by Dover of Emission Allowances. 41
