According to a recent LinkedIn post from Linea Energy LLC, the company has closed a preferred equity financing deal with DESRI for the Duffy Battery Energy Storage System in Matagorda County, Texas. The project is described as a 235 MW / 470 MWh utility-scale storage asset that is moving closer to completion and is intended to provide dispatchable capacity to the Texas grid.

The post characterizes Duffy BESS as a core asset within Linea Energy’s portfolio and positions it as evidence of the firm’s capability to deliver complex, utility-scale clean energy projects alongside institutional capital partners. The involvement of DESRI and legal advisor Orrick, Herrington & Sutcliffe LLP suggests the project may be structured to attract further infrastructure-focused capital.
As shared in the post, Linea Energy also points to an upcoming 500 MW AC Duffy Solar project that will be co-located with the BESS facility, which could create one of the larger integrated clean energy sites in Texas. For investors, a combined storage and solar hub may enhance revenue diversification through energy arbitrage, grid services, and wholesale power sales in a volatile ERCOT market.
The emphasis on dispatchable storage and resilient, low-carbon infrastructure indicates a focus on segments of the energy transition that may command premium valuations relative to standalone renewables. If successfully executed, the Duffy cluster could strengthen Linea Energy’s competitive position in Texas and potentially serve as a template for future co-located storage and solar developments in other high-demand grids.
