The National Electrical Manufacturers Association (NEMA) commends the Federal Energy Regulatory Commission (FERC) for a recent decision that will improve the reliability and efficiency of the electric grid.
In its final rule, FERC has allowed locational marginal price (LMP) to be paid to demand response (DR) resources in organized wholesale energy markets. This means that electricity customers can enter into a voluntary agreement to be compensated to reduce usage when a utility transmits a DR signal.
LMP, the same market rate paid to generation resources, will be paid to DR technologies in situations when it meets a cost-effectiveness threshold. This threshold will consider DR's impact on remaining loads to prevent ratepayers who are not engaged in DR from having to incur a greater cost per unit.
Cost-effectiveness thresholds are to be determined by regional transmission organizations and independent system operators by July 22, 2011, in a filing to FERC.
Because interaction between utilities and buildings is central to the smart grid, NEMA's High-Performance Building Council is developing with ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) SPC 201, the interoperability standard that will allow all loads, generators and meters within a high-performance building to communicate in a common “language” with a utility.
Providing LMP in wholesale markets will encourage building owners to invest in DR to make their operations more efficient, from both energy and economic standpoints. DR is one of the eight priority areas identified in the National Institute of Standards and Technology (NIST) Framework and Roadmap for Smart Grid Interoperability Standards.
