While New England remains a summer peaking electricity system (with a forecasted 2018 summer peak around 25 percent higher than the forecasted 2018/2019 winter peak), winter peak forecasts are important for assessing the impacts
of electric system reliability during a period when much of New England's energy infrastructure is dedicated to space heating (i.e., when interstate natural gas pipelines are used both for electricity generation and for heating homes and businesses).
Taking reduced forecasts for winter peak demand into account is essential in future analyses of
electric system reliability impacts — these new projections of demand were not used in ISO New England's recent Operational Fuel Security Analysis study, but were analyzed in a follow - up report.
This work includes examining the impact of power generation on water supply (and water supply
on electric system reliability), the costs and risks associated with building large new power plants, and the economic impacts and reasonableness of converting fossil fuel and nuclear plants from once - through to closed - cycle cooling systems.
In this conversation, we unpack some of the big themes we're grappling with as 2018 unfolds: coal demand,
electric system reliability, and possible directions for climate policy.
Electric system reliability: The degree to which the performance of the elements of the electrical system results in power being delivered to consumers within accepted standards and in the amount desired.
«In addition,
electric system reliability could be compromised by coal retirements and new environmental construction projects caused by this proposed rule and other EPA regulations,» said Aric Newhouse, vice president for government relations at the National Association of Manufacturers.
