SMA Solar Technology AG—Press Release SMA to deliver operations and maintenance services for TerraForm Power’s North American solar fleet  Niestetal, Germany, November 27, 2019—SMA America, the U.S. subsidiary of SMA Solar Technology AG (SMA/FWB: S92), has signed a 10-year framework agreement with TerraForm Power for SMA to provide operations and maintenance (O&M) services for TerraForm Power’s North American solar fleet. Starting in early 2020, the companies will enter into long-term project-level service agreements and transition operations to SMA. The 10-year agreement covers approximately 1 gigawatt of TerraForm Powers’ existing solar portfolio. “We are pleased that TerraForm Power has selected SMA as the O&M services partner for its North American solar fleet. With this award SMA is strengthening its position among the top providers of O&M services,” said Jürgen Reinert, Chief Executive Officer of SMA. “As a leading inverter repowering specialist SMA offers solutions that can replace obsolete inverters thereby enhancing plant performance. This includes repowering of defunct inverters when original equipment manufacturers no longer support equipment. Our nationwide service footprint and global presence give us an additional advantage.” SMA is uniquely qualified to serve as the custodian of Terraform Power’s assets given its knowledge of inverter technology and more than 35-year experience in photovoltaics technology. SMA’s expertise reduces TerraForm Power’s operational risk and aligns with the latter company’s objective to maximize production and improve reliability. “We are pleased to sign an innovative framework agreement with SMA to oversee O&M activities for our North American solar fleet and believe this agreement will prove to be an important operational milestone for TerraForm Power,” said John Stinebaugh, Chief Executive Officer of TerraForm Power.  This new partnership will support TerraForm Power’s North American solar fleet, consisting of both distributed generation and utility-scale North American Electric Reliability Corporation (NERC) solar facilities. With this partnership, SMA now represents 3.2 GW of O&M service in the Americas region and 4.5 GW globally.
