ABO Wind commissions its first battery storage project
ABO Wind is using the experience gained from this project for further storage projects already in planning.
- Battery storage for waste disposal company Abfallentsorgung Kreis Kassel replaces emergency diesel generator
- 150 kVA storage system increases the use of photovoltaic self-consumption electricity
- Further storage projects in advanced planning stages
(Wiesbaden/Kassel, December 3, 2020) ABO Wind has designed and successfully commissioned a battery storage of 150 kVA (445 kWh) and its grid connection for the waste disposal company Abfallentsorgung Kreis Kassel in Hesse, Germany. The battery storage replaces a previous diesel generator for emergency power supply and steps in if, for example, an error occurs in the public grid. It also stores the solar electricity produced by the waste disposal company with its own roof-mounted and open field plant and enables the customer to use a larger proportion of its own green electricity.
In the event of an error in the public grid, the battery storage system sets up an island grid and provides the necessary grid frequency and voltage. It switches back to grid-connected operation as soon as the public grid is available again. "In order to implement this successfully, a great deal of planning was required in comparison to wind or solar parks," explains project manager Julian Gerstner. "We are very pleased to have successfully completed such an ambitious project". The storage system can be expanded modularly by a further 30 percent capacity and can thus cover the customer's future increasing energy demands.
ABO Wind was responsible for the technical engineering, procurement and construction of the battery storage system as well as the project management for the turnkey delivery. The project developer also mediated between the customer and the grid operator.
ABO Wind will use the experience gained from this first complex storage project to realise the three hybrid power plants for which it has secured tariffs in the innovation tender 2020. In addition, the project developer is currently implementing a hybrid system of photovoltaic, battery and electric charging station at its headquarters in Wiesbaden, Germany. It will supply the company fleet with green electricity.
