Case Study: Hybrid XT Retrofit on MHI Turbines

ALLETE Clean Energy, a renewable energy company based in Minnesota, U.S., was suffering from reliability issues coupled with long leads times for the turbine control sensors that come stock on their Mitsubishi 600kW turbines. The stock sensors were also minimally heated, so icing events easily overwhelmed them. These problems were causing lost production, revenue hits, and reduced technical availability.

Case Study: Meeting Vietnam’s Solar Monitoring Requirements with NRG Solar Solutions

In 2017, the Vietnamese government issued a requirement that to obtain a commercial operation permit, solar plants producing 30 MW or higher must have a met station on-site, to ensure accurate measurement of available energy. VREE teamed up with Digi Technologies to create a monitoring solution to satisfy this requirement.
