Renewable Energy – Maryland and the District
· In Maryland and the District, the law directs electric suppliers to buy renewable energy credits (RECs) – not renewable energy itself – in amounts sufficient to meet each year’s Renewable Portfolio Standard (RPS)
· A “REC” is a credit associated with the verified production of one megawatt hour of electricity from a renewable energy facility
· If a supplier does not purchase enough RECs in any given year, it must pay an alternative compliance fee to make up the difference
· The sellers of electricity in each jurisdiction must meet their portion of that year’s RPS requirement based on their percentage of load in each jurisdiction

Pepco and the RPS Standard
· Pepco is a supplier of electricity in both jurisdictions· Because of deregulation and customer choice, Pepco
supplies electricity to some but not all of its customers – it’s called Standard Offer Service (SOS)
· HOWEVER, Pepco does not own generating stations, so how can it provide SOS and meet RPS standards?
· Pepco buys the electricity needed to supply SOS customers from other electricity suppliers, through auctions supervised by the PSC
· The SOS supply purchased through those auctions includes the costs of RPS compliance
· The generators that provide electricity for Standard Offer Service supply must either buy their share of RECs, or pay an alternative compliance fee

RPS Facts – Maryland and the District· RECs are classed as either Tier I or Tier II· Tier I includes wind and solar, among other technologies· Tier II chiefly means large hydro and solid waste· Tier II is to be phased out over time· Most facilities can be located in and around the 13-state PJM
region – not just Maryland or the District· Solar requirements are “carved out” of the total RPS requirements
– a special subset of RECs just for solar, called “SRECs”· Both Maryland and the District have moved to limit SREC
eligibility to solar facilities located within the State/District· New Maryland legislation just proposed by Governor O’Malley
would create a new subset of Tier I RECs, this time for offshore wind facilities

What Else is PHI Doing on Renewable Energy?· In Delaware, PHI utility Delmarva Power buys RECs directly to
meet RPS requirements· Delmarva Power entered into long-term contracts with Maryland
and Pennsylvania wind farms that are operational · Delmarva Power is working with Bloom Energy to build a large
scale fuel cell generation project in Delaware· Delmarva Power is working with developers on large scale solar
projects in Delaware· PHI utility Atlantic City Electric helped pioneer the offshore wind
renewable energy credit carve out in New Jersey, which Governor O’Malley has incorporated into his offshore wind bill
· PHI subsidiary Pepco Energy Services provides energy savings and renewable energy solutions as part of its services to commercial and government customers
· Pepco and Delmarva Power MD are looking into the feasibility of proposing utility-owned, large scale solar projects to the MPSC. However, the SOS procurement process complicates the subject
