The Public Service Commission has voted to spend up to $181,000 in ratepayer funds to study the potential for customer-owned generation, paying special attention to low-income households. The results could inform the commission’s policy decisions in the coming years, particularly on how to allocate resources within Focus on Energy, the statewide energy savings program.

“This type of study is going to be essential to figure out what the balance is between renewables and efficiency,” said Commissioner Tyler Huebner, who noted the potential for energy savings is diminishing as LED bulbs become the standard. “If we don’t have this study, we’re going to be guessing in the dark.”

Wisconsin typically studies the potential for energy efficiency gains every four years, but it hasn’t looked at solar energy since 2009 when rooftop solar was little more than a novelty. As of 2019, there were 6,646 customer-owned systems with a combined capacity of roughly 100 megawatts.
