The Maryland Public Service Commission (PSC) enacted net metering rules in Maryland in 1997. In 2004, the standards were modified to allow wind and eligible commercial units to net meter. The rules were then further extended in 2005 to include biomass as an eligible source and to allow net metering to systems up to 500 kW in certain cases. Maryland's net metering law was amended twice in May 2009 to expand the definition of "eligible customer-generator". The first bill, S.B. 981, revises the definition slightly to allow for third-party ownership structures (i.e., the PPA model) not permitted under the current law. The second bill, H.B. 1057, extended net metering to CHP systems of 30 kilowatts (kW) or less. Amendments, enacted in April 2007 along with an enhanced state renewable portfolio standard (RPS), raised the maximum capacity of all eligible systems from 200 kilowatts (kW) to two megawatts (MW). Systems owned or leased (see note above for change effective July 1, 2009) by residents, businesses, schools or government entities that generate electricity using solar, wind or biomass resources are eligible for net metering. Other important details of Maryland's net metering policy include: - Net metering is available statewide until the aggregate capacity of all net-metered systems reaches 1,500 MW. (The aggregate limit on net metering was 34.7 MW prior to the 2007 amendments.) - System size is generally limited to 2 MW, except micro-CHP resources are limited to 30 kilowatts (kW). Systems must be primarily intended to offset all or a portion of a customer's on-site energy requirements and are limited in size to that needed to meet 200% of the customer's baseline annual electricity use. - Net excess generation (NEG) is generally carried over as a kilowatt-hour credit (i.e., at the retail rate) for 12 months.* Compensation for any NEG remaining in a customer's account after a 12-month period ending in April of each year is paid to the customer at the commodity energy supply rate. - Customers own and have title to all renewable-energy credits (REC) associated with electricity generation by net-metered systems. - Meter aggregation (either physical or virtual) is permitted for customers that use electrical service for agriculture, non-profit organizations, and municipal governments or their affiliates. - The PSC must file with the Maryland General Assembly detailed annual reports (see 2011 Net Metering Report) describing the status of the state's net-metering program. |
