RENEW Energy Maintenance and DEIF A/S Join Forces to Deliver Control & Pitch Retrofit Solutions for North American Wind Energy Producers

Sioux Falls, 26 April 2021

RENEW Energy Maintenance, LLC (“RENEW”) and DEIF A/S have signed an Authorised System Integrator (ASI) agreement to supply control & pitch retrofit solutions for the North American market.

This agreement will expand RENEW and DEIF A/S efforts to deliver life extension and performance improvement solutions continuing to help owners maximize their asset performance. The agreement covers all wind energy platforms that Deif serves and grants RENEW exclusivity to the Suzlon Energy related DEIF products in North America.

Control and Pitch Retrofit solutions are a cost-effective and sustainable way of improving AEP and offer fast ROI for wind farm owners and operators. With the advanced technology in modern wind turbines, such projects require extensive application know how, quality solutions, and high flexibility. By joining forces in the wind turbine retrofit business, RENEW and DEIF bring a strong combined offering to the market.

Significant potential

Nick Siddens, Director of Operations at RENEW, remarks, “The products and engineering capabilities DEIF brings to controller upgrades are unsurpassed. DEIF impressed us throughout the development of the Suzlon platform upgrades and we are very excited about this partnership. With multiple projects completed and more on the schedule, we see significant potential for controller upgrades and look forward to expanding in the North American market.”

Best possible step forward

“Working with RENEW has been a success from the start,”, says Jean S. Felber, Global Business Development Manager, Wind at DEIF A/S. “I see this agreement as the best possible step forward. Together, with RENEW, we will be able to provide end-to-end retrofit solutions, with optional spare part suppliers and OEM independent services. Wind turbine owners in North America will now be able to get first class service and life extension possibilities on their ageing assets. It will enable both companies to support our customers even better”.
