NEW YORK--(BUSINESS WIRE)--The Northeast Power Coordinating Council, Inc. (NPCC) today released the results of its annual summer reliability assessment. The assessment concludes that the NPCC Region will have an adequate supply of electricity this summer, based on thousands of simulations covering a wide range of system and weather conditions.
The overall NPCC forecast for electricity peak demand has decreased by about 1,100 MW from last year’s forecast to 104,137 MW. This continues a multi-year trend of declining forecast demand due to energy efficiency and conservation initiatives along with continued increase of “behind-the-meter” photovoltaic resources in New York, New England and Ontario.
Since last summer, NPCC’s installed net capacity has increased by approximately 3,000 MW to 161,307 MW. “About two-thirds of the new capacity consists of natural gas-fired generation primarily with dual-fuel capability located in New York and New England. The remaining capacity consists of Canadian renewable wind and hydro resources,” said Edward Schwerdt, President and CEO of NPCC.
For New York City, New York State, New England and Ontario, an adequate supply of electricity is forecast. The winter peaking Québec and Canadian Maritime Provinces are expected to meet forecasted electricity demand by a wide margin.
“Over the past several years, the combination of reductions in expected peak demand, increased resource capacity and transmission system improvements has made the NPCC system more reliable,” added Schwerdt.
The assessment considered an array of severe system conditions including the impact of: 1) extended maintenance; 2) reductions in demand-response programs; 3) reductions in the ability to import power from neighboring Regions; 4) transmission constraints; and 5) extreme weather characterized by wide-spread and prolonged heat waves with high humidity and temperatures.
Established operating procedures are available, if needed, to maintain reliability for the unlikely simultaneous occurrence of severe system and extreme weather conditions.
A summary of the NPCC 2018 Summer Reliability Assessment is available at: www.npcc.org on the Home Page under the “Latest News” header.
The NPCC geographic region includes the State of New York and the six New England states as well as the Canadian provinces of Ontario, Québec and the Maritime provinces of New Brunswick and Nova Scotia. Overall, NPCC covers an area of nearly 1.2 million square miles, populated by more than 56 million people. In total, from a net energy for load perspective, NPCC is approximately 45% U.S. and 55% Canadian. With regard to Canada, approximately 70% of Canadian net energy for load is within the NPCC Region.
One of NPCC’s responsibilities is to coordinate international electric power grid reliability for Northeastern North America. Toward that end, NPCC annually performs comprehensive seasonal assessments of electricity supply and demand reliability for eastern Canada, New England and the City and State of New York. These assessments require months of detailed preparation and are performed with the participation of regional electricity power grid operators and planners.
