Greensmith, E.ON, Tucson Electric Power Complete Iron Horse Battery Energy Storage Project

EMERYVILLE, Calif. & HERNDON, Va.–(BUSINESS WIRE)–Greensmith Energy, a leader in advanced energy storage software and
services, E.ON Climate and Renewables, and Tucson Electric Power (TEP)
will host a ribbon-cutting ceremony on June 1 to inaugurate the Iron
Horse Battery Energy Storage Project.

The 10 megawatt (MW) / 2.5 MWh energy storage system at the University
of Arizona Science and Technology Park will provide frequency response
and voltage control. The project illustrates the growing trend of
programmable battery storage replacing fossil generation as the
least-cost solution for grid reliability services. The system also
provides integration for a new 2 MW solar array.

Greensmith provided design, integration and commissioning of the
turn-key energy storage system that leveraged LTO (lithium titanate
oxide) batteries suitable for high frequency, high power applications.
The company’s industry-leading GEMS software control platform will
deliver real-time monitoring, integrated control and system optimization
and safety throughout life.

“Fast-responding energy storage software will be critical for
maintaining grid stability as the Tucson area prepares to add hundreds
of megawatts of new renewable energy capacity in the years ahead,” said
Greensmith CEO John Jung. “We are proud to partner with E.ON to help
make Tucson Electric Power’s clean energy vision a reality.”

Greensmith announced its participation in the Iron Horse project last
summer, following project approval from the Arizona Corporation
Commission for a ten-year agreement to use the project for ancillary
services. Greensmith, E.ON, and TEP broke ground late last year.

Iron Horse supports TEP’s goal of delivering at least 30 percent of its
power from renewable resources by 2030, doubling Arizona’s 2025
statewide benchmark.

On May 15, Greensmith announced that Wärtsilä (Nasdaq OMX Helsinki:
WRT1V), a global leader in advanced technologies and complete lifecycle
solutions for the marine and energy markets, has signed an agreement to
acquire the company. The transaction, subject to US regulatory approval,
is expected to close by July 2017.
