Hensel Phelps delivers resilient clean energy infrastructure
Hensel Phelps is delivering sustainable, resilient energy solutions across multiple municipal, federal and research projects to reduce reliance on the national grid and enable operational independence.
Project deployments and technical details: Sunnyvale Civic Center microgrid integrates a 680 kW photovoltaic array paired with 250 kWh battery storage (able to sustain essential services for multiple days); SSA NSC is the first federal data center to achieve Uptime Tier III with a 1 MW solar PV system feeding a bi-directional metering system; CARB Southern California Headquarters is powered by a 3.8 MW PV system and 1.5 MWh BESS targeting LEED Platinum and Zero Net Energy (ZNE) goals; Caltech CNRB operates independently via a Bloom hydrogen fuel cell energy system with a diesel emergency generator providing 16 hours of fuel-backed power; Contra Costa County EOC includes a 750-kW generator (underground fuel tank), 50,000-gallon potable and 35,000-gallon fire water tanks, a 12,000-gallon sanitary sewer holding tank, and expanded PV/battery capacity to 162 kW offsetting ~70% of the building’s energy cost.
Context, drivers and cited statistics: The piece cites the U.S. Department of Energy warning of retirement of 104 GW of firm power capacity and rising outage risk, and Deloitte’s projection of up to $1.4 trillion in capital investments needed from 2025 to 2030; it also references estimated business costs of outages at $150 billion annually (Pew Research Center).
