Wind and solar power are well-positioned to quickly respond to the increasing load data centers are putting on Wisconsin’s electrical grid, a renewable energy expert argues.
Wisconsin has become a hotbed of data center activity over the past few years, underscored by Microsoft’s more than $7 billion in investments in the southeastern region of the state. Increasing demand on the electrical grid is normal, but data centers are only adding to that demand. The Lawrence Berkeley National Laboratory predicts data center electricity consumption will grow from 176 terawatt hours in 2023 to between 325 and 580 terawatt hours in 2028, which would represent 6.7 percent to 12.0 percent of annual U.S. electrical consumption.
David Neely, EDP Renewables’ Senior Director of Development for the central region, said wind and solar power is better positioned than other power generation sources to quickly respond to those demands.
“If you just think simple supply and demand, we do support, kind of an all-in approach for what these utilities can get online. It’s what they need to get online, because there’s a rush to do capacity,” he said. “Renewables is a big, important factor in that.”
Some wind and solar projects can be built and come online in as little as a year, Neely said. That’s compared to roughly four years for traditional natural gas and coal-powered plants, according to International Energy Association data. The same IEA data also shows roughly two-and-a-half years to bring renewable projects online, though. 
Wisconsin’s goal to have all electricity consumed be 100 percent carbon-free by 2050 is also an attraction for both data center and renewable investment, Neely said.
