Load Profiles, PLCs & Energy Settlement

BGE is a member of the PJM Interconnection, L.L.C. (PJM). PJM is responsible for the operation and control of the bulk electric power system throughout major portions of five Mid-Atlantic States and the District of Columbia, including BGE's local distribution territory or BGE zone. With the implementation of the PJM Open Access Transmission Tariff on April 1, 1997, PJM began operating the nation's first regional, bid-based hourly energy market. PJM enables participants to buy and sell energy, schedule transactions and reserve transmission service. PJM provides accounting and billing services for these transactions using information supplied by each member utility. In addition, it operates the competitive wholesale energy market for the region and facilitates open access to transmission. Electricity suppliers who sell electricity to customers within the BGE zone must become Load Serving Entity (LSE) members of PJM, or contract with a third party LSE. Detailed information including rules for participation in the market administered by PJM may be found on PJM Interconnection, LLC.

PJM's foremost responsibility is the safe and reliable operation of the transmission system and ensuring the reliable supply of energy from generating resources to wholesale customers. To ensure reliable supply and transmission, PJM requires that each LSE serving retail load within PJM be responsible for its portion of the supply and the transmission resources required as described in the links below.

Reliability Pricing Model (RPM)

On June 1, 2007, PJM will replace their existing capacity construct with their new resource adequacy construct known as the Reliability Pricing Model (RPM).  The purpose of the RPM is to provide a long-term price signal for capacity resources and LSE's unforced capacity obligations that are consistent with the PJM Regional Transmission Expansion Planning process.  According to PJM, this new model should provide sufficient resources to ensure the reliability of the PJM region for future years.  For more information, go to the Reliability Pricing Model link on the PJM web site.
