3010 Integrated Resource Planning for the Provision of Standard Offer Service by Delmarva Power & Light Company

1.0 General

1.1 The reliability of electric service and the security of energy supply are of great importance to the Delaware Public Service Commission (“Commission”), because they are essential services to the citizens of Delaware. This regulation, in support of 26 Del.C. §1007, sets forth the minimum Delmarva Power and Light (“DP&L” or “Company”) Integrated Resource Plan (“IRP” or “the Plan”) requirements needed to ensure a cost effective, price stable, reliable, efficient and environmentally sound energy supply for all Standard Offer Service (“SOS”) customers.

1.2 Nothing in this regulation relieves DP&L from compliance with any requirement set forth under any other regulation, statute, or order. Compliance with this regulation meets the minimum IRP requirements. Compliance with this regulation does not imply IRP approval or automatic cost recovery.

1.3 In accord with 26 Del.C. §1007, DP&L, as the Standard Offer Service Supplier, shall file an IRP on December 1st, 2006 and on the anniversary date of the first filing date every other year thereafter (i.e. 2008, 2010 et seq.). The Company may request and the Commission may change the filing date for good cause shown. These regulations shall apply to all IRPs filed pursuant to 26 Del.C. §1007. These regulations shall not apply to an IRP docket opened prior to the effective date of these regulations.

1.4 The IRP shall be filed in compliance with normal Commission policies and practices.

1.5 The IRP shall identify the year of the filing, the individuals responsible for its preparation and those individuals who shall be available to respond to inquires during the Commission’s review of the plan.

1.6 Because an IRP may contain trade secrets and commercial or financial information, the Company may request that information, required under this Regulation, be classified as confidential, proprietary and/or privileged material. The Company must explain how the material deemed confidential, if disclosed, will cause substantial harm to the competitive position of the Company or other party. The Company must attest that such information is not subject to inspection by the public or other parties without execution of an appropriate proprietary agreement. In requesting such treatment of information the Company is also obligated to file an additional copy of the information, excluding the confidential or proprietary information. The Commission, in accordance with Rule 11, Rules of Practice and Procedure of the Delaware Public Service Commission, effective May 10, 1999, shall treat such information as “confidential, not for public release” upon receipt of a properly filed request. Any dispute over the confidential treatment of information shall be resolved by the Commission, designated Presiding Officer or Hearing Examiner. Confidential utility documents shall be presented under separate seal.

1.7 Commission Recognition of a filed IRP implies only that the IRP is in compliance with the administrative requirements of this regulation and the Electric Utility Retail Customer Supply Act of 2006 (“Act”), 26 Del.C. §1001-1012. The recognition or ratification of an IRP does not confer or imply Commission approval unless so stated by an Order of the Commission. Approval or disapproval of an IRP must be made by the Commission after, at a minimum, Staff’s analysis of and public comment on the proposed IRP. Any specific ratemaking treatment for the IRP or any portions thereof is neither directly nor indirectly guaranteed by virtue of the recognition or ratification.

1.8 The utility shall provide whatever detail and commentary necessary to demonstrate that it has met or exceeded the planning requirements as set forth in this regulation. An effort shall be made to ensure that the IRP is clearly stated and can be readily comprehended by the Commission, State Agencies, and other interested parties. The IRP shall include an Executive Summary.

1.9 Compliance with this regulation is a minimum standard for IRPs. The Company needs to exercise its professional judgment based on its systems and customer needs. The Company shall include all information that assists the reader to fully understand the IRP concept and the Company’s IRP to meet SOS energy needs.

1.10 This regulation requires the maintenance and retention of supply resource planning data and the reporting of IRP achievements on an annual basis starting in 2009 to the Commission, Governor and General Assembly. The Company shall retain such data, consistent with Federal data retention guidelines and make it available for further review as necessary.

1.11 The Company shall submit a total of 14 copies of its IRP - eight (8) copies to the Commission, two (2) copies to the Controller General’s office, two (2) copies to the Office of Management and Budget; two (2) copies to the Division of the Public Advocate and two (2) copies to the Energy Office/DNREC. The Commission may request up to six (6) additional copies of combined and common filings as may be necessary for review.

1.12 These Integrated Resource Planning Regulations shall be effective for IRP dockets opened after the effective date of these regulations and may be reviewed, revised, or extended as necessary to ensure continued compliance with 26 Del.C. §1001-1012 and to ensure adequate SOS energy supply.

1.13 Failure of the Company to file an IRP or to provide progress reports as required may subject the Company to the penalty and remedial provisions of the Delaware statute (26 Del.C. §1019).

1.14 The Company shall make the full IRP, including any appendices or other supporting materials, available to the general public on its web site and shall update these materials on the Company’s web site to remain current with all subsequent updates, revisions or other changes made to the IRP by the Company.

“Portfolio” or “Resource Portfolio” means the combination of physical assets (e.g. electric generating, self generating, and transmission assets), financial products (e.g. Supply Contracts for energy and related services), market resources (e.g. spot market energy purchases), DSM and DR programs, and Customer-Sited Generation resources, both renewable and non renewable, that the Electric Distribution Company uses to satisfy current and future energy procurement requirements for SOS customers, which is designed to manage the risk of adverse price changes to SOS customers.

“Plan Objectives” means the targets or goals of an IRP needed to measure the impact and/or success of the plan’s actions. Such goals or targets must be definitive, measurable and verifiable. Refer to 1.1 for IRP objectives.

“Price Stability” means the lack of significant variation in either the real price or nominal price paid by SOS customers over the planning period.

“Real Price” means the value after adjusting for inflation. Real price is expressed in constant dollars reflecting buying power relative to a base year.

“Reliability” means the degree of performance of the elements of the bulk electric system that results in electricity being delivered to customers within accepted standards and in the amount desired. Reliability may be measured by the frequency, duration, and magnitude of adverse effects on the electric supply. Electric system Reliability can be addressed by considering two basic and functional aspects of the electric system – Adequacy and Security.

• Adequacy is the ability of the electric system to supply the aggregate electrical demand and energy requirements of customers at all times, taking into account scheduled and reasonably expected unscheduled outages of system elements.

• Security is the ability of the electric system to withstand sudden disturbances such as electric short circuits or unanticipated loss of system elements.4

• As applied to distribution facilities, Reliability is further described as the degree to which safe, proper and adequate electric service is supplied to customers without interruption.

“Resource Portfolio” means “Portfolio.”

"Retail Competition" means the right of a customer to purchase electricity from a certified electric supplier.

Where DR programs are new, the Company shall summarize the anticipated benefits with respect to load reductions and provide supporting material to justify the new program.

5.8 The Company shall collaborate with the SEU and appropriate State Agencies in its evaluation of Customer-Sited Generation resource options. The Company may enter into a contractual relationship with the SEU or other energy service providers to implement a Customer-Sited Generation resource option strategy.

5.9 The Company shall assess the Resource Portfolio options against the set of Plan Objectives and criteria.

6.0 Plan Development

6.1 The Company shall conduct an Integrated Resource Evaluation in formulating its potential plans for supply and demand-side resource scenarios. The Company shall describe the mechanism or process by which the Load Forecast and options have been blended into the various IRP scenarios. In integrating its supply and demand-side resources, the Company shall:

6.1.1 Prepare an evaluation that takes into consideration the life expectancy of the resource, if the resource provides capacity and/or energy, any improvements to system Reliability, the dispatchability of the source, any lead time requirements, the flexibility of the resource, the Generation Attributes of the resource, the efficiency of the resource, and the opportunities for customers’ participation. The valuation shall assess the probability of securing the options according to modeling information used, including any key assumptions. The Company shall provide the estimated energy and capacity impacts for each option and the rationale behind the estimate.

6.1.2 Prepare a contingency plan that shall include a discussion of how the Company might alter the proposed IRP in the future if the key planning assumptions used to develop the proposed IRP in the future turn out to be different than what was assumed in preparing the proposed IRP.

6.1.3 Evaluate the cost-effectiveness of the options from the perspectives of the utility and the different classes of ratepayers. Any cost evaluation should be based on real prices, the Company, should it so choose also may provide a cost evaluation using nominal prices.

6.1.4 Include a current evaluation, detailing and giving consideration to environmental benefits and externalities associated with the utilization of specific methods of energy production. This evaluation need not be based on original research by the Company and may rely on published research and peer reviewed scientific and/or medical studies commonly available. To the extent that any reliable, relevant peer reviewed published research and scientific and/or medical studies commonly available include life cycle analyses encompassing energy extraction, transport, generation and/or use, the Company shall include such research and studies in its evaluation.

6.1.5 The IRP shall not include any assumptions that externalities are adequately addressed by either the fact that the IRP meets the Renewable Energy Portfolio Standards, satisfies the Energy Efficiency Resources Standards, or that the generating units to be utilized comply with existing environmental regulations. This rule does not, however, preclude a potential conclusion that the Renewable Energy Portfolio Standards or Energy Efficiency Resources Standards in effect at the time adequately address externalities.

6.1.6 Evaluate the financial, competitive, reliability, and operational risks associated with the options recommended by the IRP and how these risks may be mitigated over the 10 year planning period. Each candidate plan shall include a discussion of the likelihood of the occurrence of such risks.

6.1.7 For the options included in the proposed plan identified in the IRP, the IRP shall include an analysis of the fuel risk associated with the proposed Resource Portfolio and how such fuel risk will be mitigated when the proposed IRP is implemented.

6.1.8 Perform sensitivity analyses on each of the candidate plans to include variations in key assumptions and to assess the likelihood of planned outcomes. The sensitivity analyses shall include among other analyses the impact of proposed or existing rules and regulations on a local, regional or national level related to climate change.

6.2 The Company shall forward a copy of the IRP to DNREC and seek input into externalities, including but not limited to, health effects.

6.3 In developing candidate plans, special attention shall be given to ensuring consistency between the IRP and typical rate- making processes. While the ultimate consumer price associated with the plan is important, the stability of rates and other factors as described in Section 5.2 need to be considered in any candidate plan selection.

7.0 Proposed Plan Selection.

7.1 The Company shall select and file the proposed IRP that is the most consistent with the criteria set forth in 26 Del.C. §§1007, 1020 and this Regulation. The Company shall provide a description of the options recommended for inclusion in the proposed IRP, including a description of the mechanism or process used for valuing each option. The Company shall describe the rationale behind its selection, including any modeling or methodology used as the basis for selection of the proposed IRP.

7.2 In filing the proposed IRP, the Company shall provide at a minimum a five (5) year forecast of supply rates by customer class that would be anticipated based on the IRP planning assumptions and recommended procurement strategy.

8.0 Implementation Plan

8.1 As part of the IRP, the Company shall file a plan needed to implement the IRP. Such Implementation Plan shall be a five (5) year action plan outlining the resource decisions intended to implement the IRP. The Implementation Plan shall include:

8.1.1 All actions to be taken in the first two (2) years and outline actions anticipated in the last three (3) years.

8.1.2 For IRPs filed on or after December 1, 2010, a status report of the specific actions contained in the previous Implementation Plan, including what risk assumptions were made and what actually occurred.

8.1.3 Schedule of key activities related to the IRP implementation.

9.0 Review and Comment

9.1 As part of the process commencing in 2009 and continuing on an annual basis, the Company shall submit a report to the Commission, the Governor and the General Assembly detailing their progress in implementing their IRPs.

9.2 The Commission, interested State Agencies, interested parties and the general public shall be provided an opportunity for review and comment on the Company’s IRP filings. The Commission shall seek input from DNREC on the issue of externalities and environmental benefits due to emissions, as the result of the proposed IRP.

9.3 Subsequent to the IRP recognition and after input from the public, and other parties, the Commission may ratify the filing of the Company’s IRP and its compliance with these regulations. Ratification that the IRP complies with the statute shall not guarantee a particular ratemaking treatment of future resource acquisitions. To the extent that the Commission determines that the IRP is not compliant with the statute or is unlikely to meet the goals of the statute, the Company shall revise its IRP to meet these requirements. Rate treatment shall be addressed in rate or other proceedings as filed by the utility or as initiated by the Commission.

9.4 The Integrated Resource Plan may be used as a factor in rate cases to evaluate the performance of the utility. Reports provided under this Regulation are subject to annual review and audit by the Commission and interested State Agencies. The Company must maintain sufficient records to permit a review and confirmation of material contained in all required reports.
