Renewable company, Diamond WTG Engineering & Services, Inc. (a group company of Mitsubishi Heavy Industries, Ltd., and Leeward Renewable Energy), announced that Leeward has extended for 10 years Diamond’s Maintenance & Service Agreements (MSAs) for five of their wind energy projects in the U.S.
The combined capacity of these renewable energy assets totals 564-MW, and the projects spread across four different states: California, Colorado, New Mexico, and Texas.

Diamond will provide service for 5 Leeward wind projects totaling more than 3,500-MW.
“We are proud that Leeward Renewable Energy has selected Diamond to service its wind farms which, in turn, contribute to America’s energy independence,” said Harm Toren, President and CEO of Diamond.
“Their decision is a reflection of the quality of our technicians, our commitment to client service and the trust Leeward has in our ability to address all aspects of wind turbine operations,” he added.
Diamond and Leeward finalized the extension of customized Maintenance & Service Agreements under which Diamond will be responsible for the performance of scheduled maintenance, minor corrective repairs, gearbox management, and supply of spare parts for the following wind projects:
- Aragonne Mesa, 90-MW (New Mexico)
- Buena Vista, 38-MW (California)
- Caprock, 80-MW (New Mexico)
