On April 5, 2018, the Pennsylvania Public Utility Commission (“PUC” or “Commission”) issued a Final Policy Statement Order on Combined Heat and Power (“CHP”).  The Commission seeks to promote and advance the development of CHP systems and facilities in Pennsylvania.  The Commission will require electric distribution companies (“EDCs”) and natural gas distribution companies (“NGDCs”) to file biennially a report that documents the utility’s strategies, programs, and other initiatives in support of CHP.  Importantly, the Final Policy Statement does not require or encourage the public release of CHP project-specific cost or usage data.

Background

In the Final Policy Statement, the PUC affirmed that CHP is an efficient means of generating electric power and thermal energy from a single fuel source, providing cost-effective energy services to commercial and industrial entities like hotels, universities, hospitals, manufacturing, and other businesses.  CHP also provides enhanced reliability for the end-user, improves manufacturing competitiveness, and reduces greenhouse gas emissions.  Other PUC-stated benefits include increased diversification of resources for generating electricity, expansion of natural gas and associated economic development, and increased security due to multiple points of power generation.

In the Final Order, the Commission established a biennial reporting requirement to reduce barriers to the development of CHP in the Commonwealth, such as 1) perceived difficulty in justifying capital investment in CHP; 2) costs of purchasing backup power during planned plant maintenance and unplanned downtime; and 3) lack uniform standards, fees, and procedures for the interconnection of distributed generation technologies.

Funding and Financial Incentives for CHP

The Commission emphasized that mechanisms to promote CHP projects should only apply to cost-effective projects and not uneconomical projects.  Because not all mechanisms for promoting CHP are administered under the Act 129 Energy Efficiency and Conservation program, the Commission expressed openness to other mechanisms but declined to establish new utility-based incentives to encourage CHP.

Creation of PUC CHP Working Group

The Commission ordered its Bureau of Technical Utility Services to initiate a CHP Working Group within 90 days of issuance of the Final Policy Statement Order. The temporary working group will discuss CHP reporting, processes, and related topics.

Definition of CHP in the Policy Statement: 52 Pa. Code § 69.3201

The PUC revised the definition of CHP by incorporating the Department of Energy’s definition, which defines CHP as the concurrent production of electricity or mechanical power and useful thermal energy (heating and/or cooling) from a single source of energy.  CHP is a type of distributed generation located at or near the point of consumption (unlike central station generation).  CHP consists of “a suite of technologies that can use a variety of fuels to generate electricity or power at the point of use, allowing the heat that would normally be lost in the power generation process to be recovered to provide needed heating and/or cooling.”[1]

The Utility Biennial Reports: 52 Pa. Code § 69.3202

In the Final Policy Statement, the Commission determined that CHP project-specific data “will not be reported or released to the public.”[2]  The Commission also emphasized that the reports will “only require the reporting include known information” as utilities will not need to generate or acquire information not known to the utilities.[3]  Further, individual customer information will be kept confidential and proprietary.[4]

All jurisdictional EDCs and NGDCs will report on proposed CHP strategies, programs, and initiatives rather than focus on historic efforts.  The report for both EDCs and NGDCs must include:

  • The utility’s detailed plans to encourage CHP development;
  • Identification of CHP systems interconnected with the utility;
    1. The location, nameplate capacity (MW), and basic operation of each system
    2. Payments made to the utility associated with the CHP interconnection
    3. Estimated projected annual energy and costs savings over life of CHP system
    4. Reliability benefits of CHP system
  • Identification of CHP systems scheduled for interconnection;
  • A discussion of challenges for CHP development;
  • A description of efforts made by the utility to obtain information for the report; and
  • The utility’s CHP system development communication strategy

In addition to the above requirements, EDCs must also report:

  • Interconnection terms and conditions (e.g., efforts to streamline procedures and contracts, dispute resolution, efforts to help larger CHP systems meet applicable interconnection standards, and recent changes to terms and conditions);
  • Monthly usage information regarding electric generation delivered to all customers with CHP;
  • The customer accounts with CHP systems; and
  • Tariffed rates for those customer accounts (including the rate design methodology for each customer, demand, and energy rate element).

NGDCs must also report:

  • Any separate rates for customer accounts with CHP systems;
  • Monthly usage information regarding natural gas delivered to all customers with CHP; and
  • NGDC capital costs incurred and not recovered from CHP customers as well as estimated incremental annual revenues associated with the CHP system interconnection.

PUC Staff Biennial Reports: 52 Pa. Code § 69.3203

The Final Policy Statement requires the Commission’s Bureau of Technical Utility Services to provide a biennial report to the Commission that summarizes and analyzes the EDC/NGDC reports, identifies government agency programs for financial incentives for CHP, and provides recommendations for further developing CHP in Pennsylvania.
