Renewable Portfolio Standards

In June 2019, Governor Mills signed legislation that increased Maine’s renewable portfolio standard (RPS) to 80% by 2030 and set a goal of 100% by 2050. In addition, the bill requires the Maine Public Utilities Commission (MPUC) to procure long-term contracts for new clean energy generation, which may be paired with advanced energy storage. In order to ensure this procurement creates significant economic benefits for Maine, the procurement weighs bids with a 70% consideration towards benefits to ratepayers (i.e. price) and 30% towards proven benefits to the economy.

In addition, this legislation [PL 2019, Ch. 477 (LD 1494 An Act To Reform Maine’s Renewable Portfolio Standard)] requires the creation of a new thermal portfolio standard to incentivize efficient heating and cooling installations; a requirement of 4% phased in by 2030.

The MPUC regulates utilities to ensure compliance with the RPS and conducts the competitive procurements. For more information please visit the MPUC webpage:

PUC Announces First Round of Procurement Project Selections (September 2020)

The Maine PUC approved 17 renewable energy projects for long-term contracts in the first round of procurements to achieve Maine’s RPS goals. Learn more here.

Renewable Energy Market Assessment

Included in the RPS legislation is a requirement for a renewable energy goals market assessment. The Governor’s Energy Office is preparing this ten-year renewable energy market assessment, which will provide important information to inform how the state meets its clean energy requirement.
