8MINUTE SOLAR ENERGY AND DOOSAN GRIDTECH INK DEAL TO DEVELOP ADVANCED PREDICTIVE CONTROLS FOR DISPATCHABLE SOLAR + STORAGE
Pilot project collaboration at Springbok 3 site meets LADWP's interoperability requirements

8minute Solar Energy has partnered with Doosan GridTech to develop an advanced energy software control solution for dispatching energy from advanced solar photovoltaic plus storage centers (PVS).

The companies will utilize the new software first at the Springbok 3 Solar Farm, part of the 448 MW Springbok solar cluster in Kern County, California, which was developed by 8minute and supplies enough clean energy for more than 152,000 households in Los Angeles. This partnership pairs Doosan's flexible software platform and energy storage expertise with 8minute's forward-thinking PVS dispatch approach to maximize asset value creation. The resulting control solution will improve PVS plant output predictability and unlock additional value streams for 8minute and its Springbok 3 off-taker, the Los Angeles Department of Power & Water (LADWP).

"Dispatchable large-scale solar paired with energy storage will be the backbone of the 21^st-Century grid. Smart, innovative software that communicates with the grid is a hugely important part of that future. Partnering with Doosan and their deep experience with energy storage control platforms is a perfect fit," said Tom Buttgenbach, President and CEO of 8minute Solar Energy. "Matching Doosan's software ingenuity with our best-in-class technology, engineering, and sophisticated infrastructure financing, we will continue to deliver results and drive down costs while increasing energy production."

Doosan's Intelligent Controller was one of the first energy storage control platforms built on open standards interfaces - a key component of the 8minute collaboration which aims to set the industry standard for how utilities communicate with and control PVS assets. This software is currently operating the award-winning Beacon Solar Plant's 20 MW energy storage system (ESS) that was designed and installed by Doosan for LADWP.

The enhanced Doosan Intelligent Controller used at the Springbok 3 site will uniquely combine several operating modes, such as active power smoothing and predictive active power response with coordinated charge and discharge, giving a smoother power output from the PVS system. The joint team will also develop PVS block strategies to provide contingency frequency support services on top of its baseline output. Additionally, active PV-only control will be initiated to more smoothly ramp the resource up and down based on solar forecasting without the need for an ESS.

The solution will use MESA-ESS as the communication standard between the site and the off-taker, LADWP. Doosan was a founding member of the Modular Energy Storage Architecture alliance (MESA).

"We are honored that the largest independent solar developer in the country has chosen us to work with them to deliver a new approach in predictive dispatch strategies," said Daejin Choi, CEO of Doosan GridTech. "This engagement capitalizes on our deep visionary legacy developing some of the earliest open standards utility-integrated storage systems, and helps us shape the next wave of PVS deployments between the developer community and their utility off-takers."

8minute Solar Energy ("8minute") is the largest independent developer of solar PV and storage projects in the United States. Founded a decade ago by President and CEO Tom Buttgenbach, 8minute has over 15 GW of solar and storage under development in California, the Southwest, Texas, and the Southeast, with more than 2 GW of solar power plants now in operation. The company has also developed the largest solar plant in the nation, the 800 MW Mount Signal solar farm in California. 8minute has one of the best development teams in the industry with a track record of delivering above-market profitability and strong financial returns on utility-scale solar and storage projects.

Doosan GridTech is an award-winning team of power system engineers, software developers and turnkey deployment experts that helps electric utilities and other megawatt-scale power producers evaluate, procure, integrate and optimize energy storage, solar power and other distributed energy resources. Its global team has designed and built over twenty energy storage installations in the Americas and Asian-Pacific regions - representing 90 MW of capacity. The firm is ranked as one of the top energy storage solution providers by Navigant Research and Bloomberg New Energy Finance and is the proud recipient of two GTM Grid Innovation awards. www.doosangridtech.com
