Stonepeak Infrastructure Partners, an infrastructure-focused private equity firm, invested $200m in Madison Energy Investments, a newly-formed solar distributed generation company. “This is an opportune time to be investing in the distributed generation solar market in the US,” said Richard Walsh, Managing Partner of Madison Energy Investments. “If you look at the demand from corporates, local and regional governments and most importantly the economic case and cost-savings to customers, the value proposition is amazing.”
