The hybrid power plant on the island of Pellworm with a total capacity of 1071  kW consists of a 771 kW photovoltaic system and a 300 kW wind energy system Enercon E-33, so it uses renewable energies from the sun and wind.

In 1983 the hybrid power plant was built on the high-radiation North Sea island of Pellworm . At that time, 17,568 solar modules of the type AEG  PQ 10–20 ( efficiency : 8% and 19 watts of power per module) with a total peak output of around 300 kW were installed. An average of 240,000 kWh was generated per year. The spa center consumed 107,000 kWh of this, and 33,000 kWh were fed into the grid. In 1992, the local electricity supplier took over the power plant, which has meanwhile been expanded to include three HSW-30 wind turbines (each with a nominal output of 30 kW) to create a hybrid power plant.

The energy supplier E.ON Hanse AG invested in 300 kW of further developed solar modules of the AEG PQ 10–40 type, which enabled a large area to be saved due to the higher module efficiency (12% to 8%). While the first photovoltaic system still required 28,000 m², the second was content with 21,000 m². A total of 600 kW of solar energy was now installed. In addition, the power plant was expanded to include an Enercon -E-33 wind turbine (300 kW). Thus, at the same time, Europe's largest hybrid power plant was created, which was able to supply electricity to approx. 350 of the approx. 1200 inhabitants island of Pellworm. In 1997 the HSW-30 wind turbines were shut down and dismantled two years later. The older part of the solar system from 1983 was shut down in 1995 due to a lightning strike that destroyed the inverters . In 2004, the operator decided to modernize the solar system from 1983 with 1,920 new Shell SE-160C solar modules. The old solar cells were recycled. A diploma thesis commissioned at the same time led to the result in 2005 that the solar modules from 1992 only delivered about a third of the possible output due to a manufacturing error. From now on, the plant operator also invested in this part of the plant and had 1265 SunTechnics STM 173F modules installed there. There are four PV systems in total:

  1. 1920 modules of the Shell SE-160C type: at 160 watts peak power per module, this makes approx. 307 kW
  2. 1265 modules of the type SunTechnics STM 173F: at 173 watts peak power per module, this makes approx. 218 kW
  3. 1104 modules of the SunTechnics STM 173F type: at 173 watts peak power per module, this makes → approx. 191 kW
  4. Various solar modules predominantly Solarnova PQ 40 / 50D with 50 watt module power with a total peak power of → approx. 55 kW

This results in a total peak PV power of 771 kW. The construction work was completed in 2006 and the 1071 kW system is fully in grid operation.

The hybrid power plant with its information center is a much-visited tourist destination on the North Sea island and is open to guests in summer. To monitor environmental radioactivity, the Federal Office for Radiation Protection installed an ODL probe on the power plant site. It is used there for radioactive early warning.

Since the spring of 2013, the hybrid power plant has been supplemented by a hybrid storage system as part of the SmartRegion Pellworm research project . The storage system consists of a lithium-ion battery (560 kWh of energy, 560 kW of charging capacity, 1100 kW of discharging capacity) and a redox flow battery (1600 kWh of energy, 200 kW of charging / discharging capacity). The aim is to better coordinate the generation and consumption of electrical energy.
