The largest electrical grid in the United States, managed by PJM Interconnection, is facing significant challenges due to the surge in data center construction and energy demand. With data centers expected to use four times more electricity by 2035 compared to today, PJM has announced plans to temporarily cut power to data centers of 50 megawatts or more during shortages, starting in June 2027. This measure follows an unsuccessful auction for additional generating capacity and is intended to prevent blackouts by balancing supply and demand during critical periods.

Under this new program, data centers affected by temporary power cuts will receive compensation and are given some notice ahead of outages, similar to traditional demand response initiatives involving large industrial users. The announcement is prompting many data centers to consider installing their own on-site power solutions, such as backup diesel generators, despite higher costs and environmental concerns. These generators, while common due to fuel availability, have faced criticism for their contribution to pollution and health impacts, as seen in the controversy around Vantage Data Centers and their Northern Virginia facility.

PJM has been under scrutiny for its management of the generation capacity and the growing load from data centers, which service an area covering 67 million customers from Virginia to Illinois. Energy prices on the grid have nearly doubled in the past year, with data centers partially blamed for the surge. This development highlights the strain that rapid technological infrastructure growth places on the electrical grid and raises questions about sustainability and energy strategy moving forward.

Meanwhile, broader concerns about technology safety are playing out in parallel, as exemplified by recent AI-related cybersecurity incidents and calls from industry leaders like OpenAI’s Sam Altman for more measured progress in AI development. These issues underline the complex challenges faced by both energy and tech sectors as they scale rapidly, requiring new solutions and revised approaches to infrastructure, regulation, and corporate responsibility.
