Maryland Renewable Energy Portfolio Standard Program -
Frequently Asked Questions
Home \ RPS Home \ Frequently Asked Questions

RPS is the abbreviation for the Renewable Energy Portfolio Standard.

A Maryland-Eligible Renewable Energy Credit is equal to the attributes associated with one megawatt-hour of Tier 1 or Tier 2 renewable energy from a certified Renewable Energy Facility.

Section 7-701(i) of the Public Utility Companies Article of the Annotated Code of Maryland provides the framework by which the states eligible to participate in the Maryland RPS Program may be determined. Renewable energy credits must be derived from a source that is either located in the PJM Region or in a state that is adjacent to the PJM Region. Renewable energy credits may come from outside the area described above if the electricity is delivered into the PJM Region. Section of the Code of Maryland Regulations (“COMAR”) defines “state adjacent to the PJM Region” as a state that shares a border with the PJM Region or which the PJM Region partially overlaps.

Renewable Energy Facilities in the following states may be eligible to participate in the Maryland RPS program:
New Jersey
District of Columbia
West Virginia
New York
North Carolina

Renewable Energy Facilities in other states may be eligible to participate if energy is delivered into the PJM system.

Fuel sources are divided in to two categories, Tier 1 and Tier 2. Tier 1 includes solar, wind, qualifying biomass, methane from a landfill or wastewater treatment plant, geothermal, and ocean, including energy from waves, tides, currents, and thermal differences. Hydroelectric power plants less than 30 megawatts in capacity are also Tier 1. Tier 2 includes hydroelectric power other than pump storage generation, poultry litter, and waste-to-energy.

“Qualifying biomass" means a nonhazardous, organic material that is available on a renewable or recurring basis, and is:
  1. waste material that is segregated from inorganic waste material and is derived from sources including:
    1. except for old growth timber, any of the following forest-related resources:
      1. mill residue, except sawdust and wood shavings;
      2. precommercial soft wood thinning;
      3. slash;
      4. brush; or
      5. yard waste;
    2. a pallet, crate, or dunnage;
    3. agricultural and silvicultural sources, including tree crops, vineyard materials, grain, legumes, sugar, and other crop by-products or residues; or
    4. gas produced from the anaerobic decomposition of animal waste or poultry waste; or
  2. a plant that is cultivated exclusively for purposes of being used at a Tier 1 renewable source or a Tier 2 renewable source to produce electricity.

“Qualifying biomass” does not include:
  1. unsegregated solid waste or postconsumer wastepaper; or
  2. an invasive exotic plant species.

For each filing, it is required that one original copy, sixteen additional copies and a compact disc or a 3.5” disk containing electronic versions of the filings be mailed in.
The Application for Certification as a Renewable Energy Facility is available on the RPS Program page of the Commission website. To file an application with the Maryland Public Service Commission, send a signed and verified original, sixteen additional copies and an electronic version of your application and attachments to the Commission's Executive Secretary in Baltimore, Maryland. Applications will be reviewed by Staff and placed on the agenda of a Commission Administrative Meeting. The Commission will issue a letter order to all applicants notifying them of the Commission's final decision.

The Generation Attribute Tracking System (GATS) is a system designed by PJM Environmental Information Services, Inc. for the purpose of tracking Renewable Energy Credits. GATS will monitor the generation of participating units and create certificates monthly based on actual output. A GATS certificate from a Commission-certified renewable energy facility will be considered a Maryland-eligible Renewable Energy Credit. Suppliers and load serving entities are required to maintain a GATS account for compliance purposess.
A complete description of the forms for the Maryland RPS Program is listed here.
An officer of the applicant should complete the various affidavits.
Yes, the affidavits should be notarized.

Whoever signs the application is required to provide authority to sign on behalf of the applicant. A letter from a corporate officer or general counsel granting and/or confirming authority to sign is appropriate. If a corporate officer or general counsel signs the application, a letter of appointment to the position is appropriate documentation of authority to sign on behalf of the applicant.
