Have you heard about virtual power plants? We hadn't either. They "find" energy already being produced by plants online. Learn about it from Grid Magazine and how that might fit into today's pressure for new generation capacity with all the energy being consumed by data centers.
Along the wide and scenic Susquehanna River near Harrisburg, Microsoft is reviving the nuclear power plant Three Mile Island. Infamous for the 1979 partial meltdown of one of its two reactors, it has been idle since 2019. But last year, Microsoft announced a deal with plant owner Constellation Energy to bring the nuclear facility’s remaining reactor back online and provide 835 megawatts of energy to help power its AI ambitions.
In some ways, this atomic handshake looks like the most palatable option for adding new energy onto an electric grid that sorely needs it. As increased demand from data centers and electrification outpaces energy supply, utility bills are on the rise and blackouts are more likely.
PJM Interconnection, a regional grid operator whose territory stretches from Chicago to Philadelphia to North Carolina, is warning of unprecedented electricity scarcity in the years ahead.
In many places across PJM’s 13-state territory, industry and officials are rushing to cover the gap with natural gas. In rural West Virginia, Microsoft is planning to power a 1.4-gigawatt data center by using hundreds of small natural gas-powered generators. Some analysts estimate the opening of the campus will cause the company’s greenhouse gas emissions to rise as much as 44%.
From an environmental perspective, Three Mile Island’s carbon-free footprint looks preferable, but it’s not as clear cut economically. The public could still bear the costs of new infrastructure required to plug the plant back into the grid through increased electricity costs. Nearby residents will also have to grapple with the plant’s considerable impact on local water resources and its demonstrated potential for nuclear meltdown.
Is there a smarter option? Indeed there is, says Michael Zimmerman, director and senior attorney of clean affordable power at the nonprofit Environmental Defense Fund.
