Title 26 Public Utilities
3000 Energy Regulations
3009 Integrated Resource Planning for the Provision of Standard Offer Service by Delmarva Power and Light Company (Docket 60)
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 plan 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 will 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 will be filed in compliance with normal Commission policies and practices.
1.5 The plan 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 business sensitive information, the Company may request that information, required under this regulation, be classified as confidential, proprietary and/or privileged material. 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, will 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 Acknowledgement of a filed IRP implies only that the plan, as put forth, does not appear to be unreasonable to the Commission at the time the acknowledgement is given. The acknowledgement of an IRP does not confer or imply Commission approval. Any specific ratemaking treatment for the plan or any portions thereof is neither directly nor indirectly guaranteed by virtue of the acknowledgement.
1.8 The utility shall provide whatever detail and commentary are 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 must 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 plans to meet SOS energy needs.
1.10 This regulation requires the maintenance and retention of supply resource planning data and the reporting of plan 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, and two (2) copies to the Energy Office. 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 through December 1, 2014 and may be reviewed, revised, or extended as necessary to ensure continued compliance with 26 Del.C. §1007 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 Delaware statute (26 Del.C. §1019).

Where demand-side 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 assess the resource 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 resource options have been blended into the various IRP scenarios. In integrating its supply and demand-side resources, the Company shall:
6.1.1 The IRP shall provide a discussion of how the Company might alter the recommended plan in the future if the key planning assumptions used to develop the recommended plan turn out to be different than what was assumed in preparing the recommended plan.
6.1.2 Evaluate the cost-effectiveness of the resource options from the perspectives of the utility and the different classes of ratepayers.
6.1.3 Estimate a range of external costs which may be intangible, in order to show how explicit consideration of them might affect selection of resource options. The utility shall attempt to quantify the magnitude of the externalities, for example, in terms of the amount of emissions released and dollar estimates of the costs of such externalities.
6.1.4 Evaluate the financial, competitive, Reliability, and operational risks associated with the resource 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.
6.1.5 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 plan is implemented.
6.1.6 Perform sensitivity analyses on each of the candidate plans to include variations in key assumptions and to assess the likelihood of planned outcomes.
6.2 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 candidate IRP which it believes is the most consistent with the criteria set forth in 26 Del.C. §1007. The Company shall describe the rationale behind its selection, including any modeling or methodology used as the basis for selection of the proposed plan.
7.2 In filing the preferred 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 an action plan needed to implement the IRP. Such plan shall be a five (5) year action plan outlining the resource decisions intended to implement the IRP. The action plan shall include:
8.1.1 Actions to be taken in the first two (2) years and outline actions anticipated in the last three (3) years.
8.1.2 For IRP’s filed on or after December 1, 2010, a status report of the specific actions contained in the previous action plan, including what risk assumptions were made and what actually occurred.
8.1.3 Schedule of key activities related to the plan 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.
9.3 Subsequent to the IRP filing and public comment, the Commission and interested State Agencies may acknowledge the filing of the Company’s IRP and its compliance with these regulations. Acknowledgement that the IRP complies with the statute, these rules and does not appear to be unreasonable, will 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 will 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.
