Leeward Renewable Energy Completes Repowering and Financing For Mendota Hills Wind Farm

New Technology and Equipment Enhance Performance, Increase Capacity

DALLAS–(BUSINESS WIRE)–Leeward Renewable Energy, LLC (“Leeward”) today announced the company
has successfully completed the full-scale repower of its Mendota Hills
Wind Farm (“Mendota”) located in Lee County, Illinois. Leeward achieved
a financial close with a subsidiary of Citi, which provided tax equity
financing for the project.

The full-scale repower of Mendota included the decommissioning of the
existing wind turbine generators (“WTGs”) and the installation of new
foundations and WTGs to maximize efficiency and extend the life span of
the wind farm. Mendota replaced the 63 legacy Gamesa WTGs with 29 SG
2.6-126 WTGs, increasing the capacity from approximately 50 MW to 76 MW.
With turbine technology improvements, Mendota will increase reliability,
performance and reduce operational cost.

Leeward entered into a long-term power purchase agreement with Digital
Reality and will provide approximately 276,000 MWhs of renewable wind
power annually. Through the construction phase of Mendota, Leeward
generated approximately 250 jobs and will increase its contribution to
Lee County in the form of property tax payments.

“This was an ambitious project that is creating tremendous benefits and
efficiency for our customers and Lee County,” said Greg Wolf, Leeward
Renewable Energy CEO. “The Mendota project illustrates the innovation
that Leeward is striving for in both our development initiatives as well
as management of our existing assets to build and maximize our
portfolio.”

In addition to working with Leeward on the repowering initiative,
Siemens Gamesa provides operations and maintenance for the sites.

The repowering of Mendota was completed on March 21, 2019.
