Currently under Maryland’s net-excess generation rules, credits are accrued when a grid-tied customer generates electricity in excess of his or her use and supplies it to the grid. The extra produced energy is discounted at the current rate of retail electricity. But excess generation over the consumers’ use is not compensated.
Under a law passed in 2010, net-energy generation is carried from one billing period to the next until either the customer requests payment for the credit at the end of a 12-month period or until the customer’s usage exceeds the generation. Under the new law, the credit appears on the customer’s bill as a dollar figure. The law should go into effect in October 2010.
Net metering is available throughout Maryland until 1,500 MW of generation in the state is net-metered. Size is limited to a 2 MW system, and it must be intended to offset a portion, if not all, of on-site energy needs. Customers own and have title to all renewable-energy credits, which can be sold to utilities through a separate incentive program. Utilities are required to install a bi-directional meter at a customer's building and offer net metering at no charge to the consumer.
The rules apply to all utilities operating in Maryland and residents, businesses, schools, and government entities can qualify for the incentive program. Under Maryland’s net-metering laws, customers that own the system outright or own it through a power purchase agreement or a lease can qualify for net-metering.
