California Energy Commission Proposed Power Source and Emissions Disclosure Regulations in California

On January 17, 2018, the California Energy Commission (CEC) released its second proposal for power source and emissions disclosure. This proposal has ramifications for the voluntary purchasing of renewable energy within California. Buyers in California, and anyone sourcing from WECC facilities that are supplying California, could be directly affected. The proposal could limit the use of renewable energy certificates (RECs) for electricity purchaser greenhouse gas claims and reporting. Possible green power supply options impacted by the proposal may include:

  • Contracts for bundled renewable electricity (e.g., physical PPAs) from California suppliers that report under the power source disclosure.
  • Financial power purchase agreements with facilities in California or serving California load.
  • Retail green power products including utility green pricing products and community choice aggregation programs that are comprised of any RECs that are sourced separately and bundled with local system power.
  • Unbundled REC purchases from California.
  • Self-supplied green power where the REC is retained by the system owner, but the power is purchased or otherwise consumed by a California supplier.

Partners may choose to submit comments until February 23 through the CEC's Comments page. More information is available at CEC's AB 1110 Implementation Rulemaking - Workshops, Notices, and Documents. Center for Resource Solutions (CRS), a non-profit organization that administers the Green-e certification program for voluntary renewable energy, has recently issued a market advisory related to the California Energy Commission Power Source Disclosure proposal.

2017 GPLA Winner Spotlight – City of Houston, Texas

Houston is the most populous city in the state of Texas and the fourth-most populous city in the United States.

In 2016, the City of Houston increased its purchase of wind renewable energy certificates (RECs) from 75 to 80 percent of the city's annual power use. Houston also entered into a physical power purchase agreement (PPA) that will supply the city with the output from 50 megawatts (MW) of solar power generated at a facility in Alpine, Texas. The 20-year PPA enables Houston to access renewable electricity without a capital outlay, in exchange for a long-term contract at a competitive, fixed price with no price escalations or inflation adjustments. Houston's solar deal is expected to save consumers more than $1.9 million per year over the 20-year term. In addition to its purchase of green power, the city has on-site solar arrays that generate more than 125,000 kilowatt-hours (kWh) annually at municipal buildings. Combined, these projects represent more than a billion kWh of green power and account for more than 89 percent of the city's municipal power needs. This makes Houston the largest municipal user of green power in the Green Power Partnership.

Houston became an EPA Green Power Partner in 2008 and won Green Power Purchasing awards in 2008 and 2014 as well as 2017.

New Resource: Green Power Supply Options Screening Tool Helps Users Decide Between Green Power Supply Options More Easily

There are many ways to purchase green power, and sorting through the different supply options can be difficult. EPA has released a new Green Power Supply Options Screening Tool to help organizations determine which purchasing methods might be most suitable. Just answer a few simple questions about your organization, and the tool will describe which supply options—for instance, green tariffs, competitive green power products, off-site power purchase agreements, etc.—might be most feasible, according to the relevant federal, state, and utility policies. You can find the new tool here.

February GPP Webinar: State of the Voluntary Green Power Market

On February 21, GPP will host a webinar examining the state of the green power market within the United States.

This annual webinar focuses primarily on the voluntary market, through which consumers and institutions voluntarily procure renewable energy for all or part of their electricity needs. The webinar will review:

  • Green power product options
  • Where these products are available
  • Resource and pricing information
  • Up-to-date statistics and trends in green power purchasing
  • Developments in new green power procurement options (i.e., power purchase agreements (PPAs), community solar programs, community choice aggregations)
  • Spotlight on large green power customers

The presentations will draw heavily on the National Renewable Energy Laboratory's recently published Status and Trends in the U.S. Voluntary Green Power Market (PDF) (63 pp, 6.8MB) as well as the Green Power Partnership's program data.

ICYMI: January Webinar--Renewable Energy Certificate (REC) Arbitrage Process

On January 17, EPA hosted a webinar explaining the process of renewable energy certificate (REC) arbitrage. REC arbitrage is a green power procurement strategy used to decrease the cost of renewable electricity use, while still allowing the organization to substantiate renewable electricity use and improve their environmental metrics. Electricity consumers often use this strategy when installing self-financed renewable electricity projects or purchasing renewable electricity directly from a project through a power purchase agreement (PPA). This webinar explained REC arbitrage and presented two case studies.

If you missed the webinar, you can review the presentations on the GPP website:

  • Christopher Kent, Program Manager, U.S. EPA's Green Power Partnership
  • Kevin Hagen, Director Corporate Responsibility, Iron Mountain
  • Jeremy King, Director of Sustainability & Campus Improvement, Denison University
