IN Brief:
- FlexGen has acquired Clean Energy Services, extending its position from software and systems into broader field execution and lifecycle support.
- CES brings commissioning and service capability across utility-scale battery and solar assets, including authorised OEM support.
- The combined business now links project delivery, operations, remote monitoring, and long-term asset availability more closely under one structure.
FlexGen has acquired Clean Energy Services, adding commissioning, maintenance, and lifecycle support capability to its energy storage software and services business. The transaction deepens FlexGen’s role in utility-scale storage by moving it further into field execution, service response, and long-duration asset support rather than leaving those functions outside the platform.
CES brings a sizeable installed-service base into the deal. FlexGen has said the acquired company services more than 1 GW of solar sites and more than 4.5 GWh of battery sites, and has commissioned more than 15 GWh of battery projects. It also adds authorised service provider relationships with original equipment manufacturers, giving the enlarged business a broader role in site support and warranty-aligned field work.
The combination also extends operational coverage. FlexGen now references two 24/7 remote operations centres in Durham, North Carolina, and Houston, Texas, while CES adds the ability to act as a NERC generator operator on behalf of customers in certain cases. That gives the business a stronger presence in the operational phase of storage assets, where performance, alarms, dispatch readiness, and augmentation planning increasingly shape project economics.
The company has set out the combined offer on its acquisition page, presenting the move as a tighter integration of software, commissioning, OEM support, and long-term lifecycle services across battery and solar infrastructure.
