Sewage treatment plants can accelerate the energy transition with smart batteries

February 24 2022

The recently published report by research institute Pondera, commissioned by the Union of Water Boards, describes the opportunities of WWTPs as smart energy hubs. And that batteries (for energy storage) can play a crucial role in this.


But what does a battery yield? How does that contribute to sustainability? And how do you handle that? SemperPower is the Dutch supplier of smart energy storage systems (batteries) and has developed a solution especially for water boards.


All water boards have agreed with the Climate Agreement with conviction. And so many projects are being started to support the energy transition and accelerate it where necessary. For example, by starting sustainable energy projects such as energy generation with solar and/or wind and also energy generation through sludge digestion. But producing alone is not enough. In fact, due to the increase in the production of sustainable energy, the energy network (the transport network) is increasingly closing up.


And it is precisely there that water boards can use their legal overcapacity on the energy network. The energy transition can be accelerated by using the grid connection of the WWTP (which is actually often only used at 4 to 5%) for the storage of sustainably generated energy in batteries. And the great thing is that the WWTP receives a fee for this: it is therefore good for the wallet and the environment.


SemperPower helps Water Boards in the field of smart storage with its AssetBooster proposition. Based on the available capacity, we ensure that optimum use is made of the overcapacity of the grid connection. As a result, the local electricity grid can be considerably relieved, according to Pondera's report. And each WWTP can make a unique contribution to achieving the goals of the Climate Agreement.


The water boards are fully involved in the Climate Agreement and are co-developers of the 30 regional energy strategies. In addition, they themselves have been working on sustainability for some time now, for example through energy production from the fermentation of sludge and (additional) energy generation from solar, wind and aquathermal energy.


The demand for and generation of sustainable energy is expected to rise sharply. However, one of the main obstacles to the energy transition is the limited capacity of the electricity grid. This is why the Association of Water Boards has commissioned research into the possibilities of using sewage treatment plants to make a local contribution to solving this problem.


We can help WWTPs to achieve energy goals from the Climate Agreement by making smart (and sustainable) use of energy storage systems. And SemperPower gives sewage treatment plants an attractive fee for this.

Why RZWIs use energy storage systems?
