Younicos, Duke Energy, and Samsung SDI to Enhance 36-Megawatt Battery Storage Plant in Texas

Younicos-Developed Hybrid Storage Control Platform Will Be Deployed at Largest Wind-Integrated Battery System in North America

AUSTIN, TX and BERLIN, GERMANY--(Marketwired - Jun 30, 2015) - Younicos Inc. has entered into an agreement with Duke Energy Renewables and Samsung SDI to provide design, engineering, construction, software integration, and testing services for the repowering of the Notrees Battery Storage facility in Texas. The first phase of the 36 MW repowered facility, which is North America's largest wind-integrated battery plant, is expected to go online in Q1 2016.

The agreement calls for Younicos to install a hybrid storage control platform to support the deployment of new lithium-ion batteries from Samsung SDI, along with post-implementation engineering services. These new batteries will operate in combination with advanced lead-acid technology currently in use at the site. It will be the first use of lithium-ion technology in the Fast-Responding Regulation Service market (FRRS), under Texas grid operator ERCOT's current market rule framework.

The Notrees system has been in operation since 2012, and has been actively participating in ERCOT's FRRS market since commissioning. The introduction of lithium-ion batteries will increase duration of discharge at the facility, enabling it to expand service delivery in the FRRS market. It will also have the capability to provide additional fast-responding services currently under development by ERCOT as part of its ancillary service market redesign.

James P. McDougall, Younicos CEO: "Younicos performs extensive engineering analysis and software simulations at our Technology Centers to continuously innovate and identify optimal solutions for intelligent storage applications. The result is this next generation of control systems at Notrees. We applaud Duke Energy's continued leadership in energy storage adoption. We're excited to work on this project with both Duke and Samsung SDI, with whom we have a long track record of successful project deployments."

Greg Wolf, President Commercial Portfolio, Duke Energy, said, "The Notrees Energy Storage Project is an important partnership with Younicos, Samsung SDI, the Department of Energy and ERCOT. This reinvestment will extend the life of the project and expand the value it provides to the market."

Woochan Kim, Senior Vice President of Samsung SDI Energy Storage, shared: "Duke Energy's Notrees Energy Storage System (ESS) is a landmark of the U.S. energy storage industry. With our most innovative lithium-ion battery technology, we are proud to provide a new heart to the ESS, and join forces with the Younicos team, who bring unsurpassed integration and software expertise in deploying and optimizing such a system."

Audrey Fogarty, Younicos VP of Product Management, added, "This new hybrid control system we've developed will accommodate planned battery replacements and new chemistry enhancements over time, as it maintains ongoing operations of the storage system. While the batteries themselves can be considered the heart of a storage resource, our sophisticated Energy Storage Management System is the intelligence -- ensuring optimal deployment of the batteries to add value to the environment and market."
