MISO Alerts – Conserve During Heatwaves
Energy Capacity Shortages Expected This Summer
Across the nation, electric-grid operators are warning that power-generating capacity is struggling to keep up with demand, an issue that could lead to warnings and possible rolling blackouts during heat waves or other peak periods this summer. The Midcontinent Independent System Operator, or MISO, oversees our regional electric grid spanning much of the Midwest, including Indiana. In late April, MISO announced that capacity shortages may need emergency conservation measures to meet summer demand. They also noted the possibility of short duration rolling outages (blackouts) to protect the grid and reduce the risk of prolonged, widespread outages. The risk of electricity shortages is rising throughout the U.S. as demand for electricity has rebounded since the beginning of the pandemic. In 2020, power requirements were lower than normal and coal and natural gas companies began exporting more of their commodities to China during that time. Additionally, due to the Ukrainian conflict more coal and natural gas are now being exported to Europe. Further, conventional power plants are being retired and there are significant supply chain and technology challenges to replace this base load power. Planned renewable energy and storage projects are being delayed and costs are rising due to these challenges. If power capacity becomes strained this summer, MISO will issue a warning and DCREMC will request from our members a temporary reduction in electric use wherever possible. For example, avoiding the use of major appliances such as ovens, dishwashers, and clothes driers until after 8 p.m. and moving your AC thermostat up a couple of degrees for a few hours. If the power transmission grid meets max capacity, the rolling blackouts will begin with brief power outages lasting no more than 30 minutes at a time. Please be prepared this summer for possible power shortages. During a MISO alert event, notifications will be posted on Facebook and e-mail or notifications sent to inform members of the need to conserve energy and the possibility of intermittent outages.
