Headquartered in Darmstadt, just south of Frankfurt, ENTEGA powers the homes of over 600,000 customers, making it one of Germany's largest suppliers of public services. Its sales subsidiary is one of the biggest regional suppliers of carbon-neutral energy and, so far, the company has invested €850 million in renewable energy. ENTEGA has a myriad of renewable plants, all with different assets, including 11 wind parks, 3 solar parks, 2 biogas plants, and 130 PV plants. By 2020, it plans to generate 1.1 billion kWh/year in green energy. With such lofty goals, the company opted to deploy the OSIsoft PI System to collect the right data and insights across disparate data sources in order to keep all equipment operating at maximum efficiency.
