- 2009 Qualified Renewable Generation: 4.19%[i]
- 2009 Renewable Mandate: 4.51%
- 2022 Renewable Mandate: 20%
Eligible Resources: Two tiered system:
- Tier 1: Solar, wind, qualifying biomass), methane from the anaerobic decomposition of organic materials in a landfill or a waste water treatment plant, geothermal, wave/tidal, fuel cells powered by methane or biomass, poultry-litter incineration facilities, and small hydroelectric plants (systems less than 30 megawatts in capacity).[ii]
- Tier 2: Hydroelectric other than pump-storage generation and waste-to-energy facilities.[iii]

Renewable portfolio history: RPS enacted in May 2004. S.B. 595 in April 2007 required 2% of energy to come from solar (in addition to the 7.5% requirement of Tier I materials). H.B. 375 in April 2008 more than doubled Tier I requirement and accelerated compliance schedule. S.B. 277 in May 2010 accelerated solar compliance schedule[v].
Credit Trading: Yes
Noncompliance penalty: Maryland law creates an alternative compliance fee schedule of 2.0¢/kWh for non-solar Tier 1 shortfalls (increasing to 4.0¢/kWh in 2011; 1.5¢/kWh for Tier 2 shortfalls; 40¢/kWh in 2009 through 2014, 35¢/kWh in 2015 and 2016, 20¢/kWh in 2017 and 2018 and continuing to decline by 5¢ bi-annually until it reaches 5¢/kWh in 2023.
