US Department of Energy Issues Emergency Orders to Protect the Power Grid During Peak Demand
US Department of Energy Issues emergency orders are being triggered by electricity demand surging to near historic levels in large parts of the United States, driven by record-breaking heat. Emergency measures allowing grid operators to tap more power sources and backup generation to lessen the chances of blackouts during one of the summer’s peak electricity demand periods were approved by federal officials. The temporary measures are designed to keep homes, businesses, hospitals and critical infrastructure powered as millions depend on air conditioning.
Why Did the Department of Energy Issue Emergency Orders?
The Department of Energy issued two emergency orders at the request of PJM Interconnection, the nation’s largest regional grid operator, under section 202(c) of the Federal Power Act. The orders give PJM the ability to bring more generating units online and despatch backup generation resources, if needed, before the highest level grid emergency is declared. The measures are set to take effect June 30 and are intended to be in place for the highest period of forecast electricity demand to help keep the grid reliable during extreme weather.
Extreme Heat Is Driving Electricity Demand Higher
Reuters – Extended heatwaves across the eastern United States have pushed up demand for electricity, as air conditioners run around the clock. PJM said power demand was projected to be near levels not seen in almost 20 years, with peak loads expected to exceed 160 gigawatts. A combination of generator outages, transmission constraints and soaring cooling demand has driven a surge in pressure on the regional power system.
What Emergency Actions Are Being Taken?
In addition to the federal emergency orders, PJM has directed the available generating facilities to operate at full capacity, and is preparing demand-response programmes that will temporarily reduce electricity demand from participating customers. Grid operators have also deployed additional reserve generation and transmission security measures to help stabilise the system. The aim of these actions is to prevent voltage reductions or rotating outages on days of peak demand.
Who Could Be Affected by the Grid Emergency?
The emergency measures are mostly affecting the PJM service territory, which provides electricity to about 67 million people in 13 states and the District of Columbia. Most residential customers will probably not notice anything right away, but large industrial customers, demand-response programmes, and backup generation systems might be told to ease strain on the grid. The idea, federal officials say, is to keep power flowing as smoothly as possible during the heat wave.
What This Means Going Forward
The emergency orders highlight mounting fears that generation capacity available in extreme weather events will be sufficient to meet soaring electricity demand. Grid operators face new challenges as data centres, electric cars and a long summer heat wave increase energy use. The current orders are short-term reliability actions, but federal officials also say there’s a larger need for more power generation, transmission upgrades and grid resilience planning as electricity demand continues to grow.
