Duke Energy Renewables' Notrees Windpower Project Receives Upgrade of Battery Storage System

LCG, December 14, 2017--Younicos announced Tuesday that it has completed the installation and commissioning of an upgraded 36-MW battery energy storage system (BESS) at Duke Energy's 153 MW Notrees Windpower Project in West Texas. The company replaced previously deployed lead-acid technology with advanced Samsung SDI lithium-ion batteries.

The Notrees system has been in operation since 2012, actively participating in Texas grid operator ERCOT's Fast Response Regulation Services (FRRS) market. The new lithium-ion battery system 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.

Duke Energy Renewables Vice President of Operations stated, "Duke Energy Renewables was a pioneer in its early adoption and installation of the Notrees Battery Storage Project, one of the largest in the nation. Investing in updated technology will extend the life of the project, enhance performance and reliability, and expand the value it provides to the ERCOT market."

In 2016, Duke Energy Renewables began a two-phase process to upgrade Notrees' older battery technology. The first phase involved replacing 50 percent of the batteries, while the system continued to operate using Younicos hybrid control software. In phase two, the remaining lead-acid batteries were replaced with lithium-ion, without any performance interruption. During this swap-out process, the remaining life of the existing lead-acid technology was maximized, showcasing the flexibility and capability of Younicos' proprietary Y.Q software.

Younicos' Managing Director stated, "We're proud to once again partner with Duke Energy to upgrade this system, which has been the largest wind-connected storage resource in North America for over five years. Our Y.Q software performed seamlessly during the upgrade process, reinforcing its flexibility and multi-mode operational capability."

"As we look ahead to integrating more storage technology with our renewables projects, the Notrees system demonstrates our ability to serve an important customer, ERCOT, and at the same time create value from energy storage systems," said Duke Energy Renewables' Managing Director of Business Development for Energy Storage.
