Landfill (or Wastewater Treatment) Methane Gas Capture and Generation

Project Description

This project seeks to utilize TVA’s Renewable Standard Offer (RSO) program to identify and implement landfill gas- and digester gas-fueled electric power generation project opportunities in the TVA power service territory. The RSO program is designed for developers of new renewable energy projects greater than 50 kW and less than or equal to 20 MW in size; and offers set prices and terms and conditions (or a “standard offer”) to promote renewable generation from qualified sources. For this project, TVA will execute long-term power purchase agreements to secure commitments for at least 10 MW of landfill gas and/or digester gas (from wastewater treatment facilities) capacity through the RSO program. This effort will consist of more than one landfill gas- and/or digester gas-fueled electric power generating facility.

Project Implementation

The project will be implemented through the RSO program, which has an application and screening process, a contractual phase, an environmental assessment and interconnection study phase, and a power generation and compliance phase. Project developers must complete all of the requirements in the contractual (including demonstrating creditworthiness) environmental assessment and interconnection phases before the RSO contract is finalized.

Each developer will receive payment for their generation based on a time-of-use rate schedule that is established the date the RSO contract is signed. For projects signed after January 1, 2013, the base average price will increase at 5 percent per year for the term of the contract. The milestones developed for the project are outlined below.

Project Milestones Dates*
Procurement of at least 6 MW of landfill gas- and/or digester gas-fueled generation capacity located in the TVA power service territory under the RSO program with the generation flowing onto the TVA grid 12/31/2012
Procurement of approximately 9 MW of landfill gas-and/or digester gas-fueled generation capacity located in the TVA power service territory under the RSO program with the generation flowing onto the TVA grid 12/31/2013
Procurement of approximately 13 MW of landfill gas and/or digester gas-fueled generation capacity located in the TVA power service territory under the RSO program with the generation flowing onto the TVA grid 12/31/2014
Provide to EPA renewable energy generation and emissions reduction data associated with these projects Semi-annually
