Case Study: Hanwha Aerospace USA (HAU) – Connecticut

Challenge

Hanwha Aerospace USA sought to reduce energy costs, improve resiliency for critical manufacturing operations, and advance sustainability goals while navigating complex state incentive programs and maintaining grid reliability in Connecticut.

Solution

Qcells delivered two integrated solar-plus-storage systems at HAU’s Cheshire and Newington facilities under a 20-year Power Purchase Agreement, supplying nearly 20% of HAU’s energy needs. As a single, end-to-end partner, Qcells provided consumption analysis, system design, permitting, construction, financing, and operations. The projects leveraged Connecticut’s Energy Storage Solutions program and federal Inflation Reduction Act incentives, with the Geli Energy Software EMS optimizing battery dispatch to meet program requirements, manage demand charges, and support grid performance.

Result

HAU became the first manufacturer to benefit from Connecticut’s Energy Storage Solutions program, achieving more than $2 million in projected utility bill savings over the contract term. The systems deliver backup power for critical loads, enhance operational resiliency, and are expected to avoid over 32,000 metric tons of CO₂ emissions. In parallel, the projects contribute capacity to the grid during peak periods, improving reliability for Connecticut ratepayers while positioning HAU as an industry leader in clean energy adoption.
