Bill Grinstead

Bill Grinstead is the co-founder and CEO of Orenda, a Brooklyn-based renewable energy company building standalone battery storage that keeps New York City's overloaded grid from buckling. A former finance professional who cut his teeth at Susquehanna International Group and the $7B private equity firm Marlin Equity Partners, Grinstead traded markets for megawatts in 2020. Under his lead, Orenda has grown into one of the largest energy storage developers in downstate New York, claiming roughly a 34% share of the NYC storage market and a development pipeline measured in the hundreds of megawatts, while handling everything from site origination and permitting to construction and live operations.
