A decentralised and flexible grid management is likely to be recognised as appropriate reaction to an increasing decentralised infeed of renewables into the transmission system. The renewable’s volatility often causes bottlenecks or overloads in the grid and consequently forces transmission system operators (TSOs) to engage in stabilising measures. After thorough and lengthy preparations, TSCNET shareholder TenneT, the Dutch-German TSO, has started the first European pilot project employing decentralised networked home energy storage systems and blockchain technology to stabilise the grid.
Partners of TenneT in this six-month pilot project are sonnen, the world’s largest company for residential energy storage, and IBM. The latter has developed the blockchain solution, while sonnen provides the pool of home energy storage systems building the network. These decentralised storage systems are integrated into TenneT’s grid via blockchain technology, which means that the TSO is able to use those systems for redispatch. In this way, blockchain technology offers possibilities to employ decentralised networks to flexibly and intelligently manage electricity flows.
Urban Keussen, chairman of the board of TenneT, values blockchain based concepts as possible royal road to the future integration of the renewables. Mr Keussen explains: “As grid operator, we are taking a new approach to better integrate decentralised renewable energy sources and secure supply. At the same time, we offer citizens the opportunity to actively participate in the energy transition.”
