Wind + Storage in Germany

Wind + Storage in Germany is not an easy business case at the moment to develop. Projects like the one below from EWE only work due to big investment from the Japanese Organization NEDO (New Energy and Industrial Technology Development Organization). In case the production of electricity by the wind park is too high for the grid or the prices at the stock are negative, the operator has to turn down the power or even completely shut the whole wind park down. The problem is that the operator gets paid the whole amount he lost due to being prevented to produce electricity. This regulation erases one major benefit a combination with energy storage would offer. Nevertheless cellution is working with wind project developers in Germany on the development of economical feasible business models that combine a broad variety of revenue streams a battery can offer to a wind park. Get in contact with us to discuss opportunities for wind+storage in Europe and we will support you during the evaluation of the business case.

O&M in Energy Storage

Operation and Maintenance is a critical factor in energy storage systems as availability is key to a successful business model and often required by contractual circumstances with customers or grid operators. Not only is non-availability lowering the revenue of a plant, it can as well causing liquidated damages or even harm business relationships on a ling term.

An battery energy storage system is complex and consists of many parts which in total requires a interdisciplinary team to cover all upcoming problems during O&M. From my time at Vattenfall in the maintenance of conventional power plants I experienced that the maintenance is limited nowadays to reactive maintenance. When a part has a failure, the asset manager reacts and mostly replace the part. In case of battery systems this methodology will not succeed on a long term as availability is a crucial factor. Here we will experience the advantages of predictive maintenance with machine learning and big data analysis to lear more about battery operational behavior and failure prediction.

Wind, solar could be self-financing by 2025 under current European electricity market design

According to the Centre on Regulation in Europe (CERRE), Large-scale solar and wind power projects may already be able to compete in Europe’s wholesale electricity market in 2025. Lower capital costs for large-scale wind and solar projects, and much higher fossil fuel and carbon prices could lead to renewables becoming self-financing by 2025. If these conditions do not materialize, more auctions and tenders may still be needed.

In our opinon at cellution battery technology can help developing more economical models for wind and solar energy in the future and may enable renewables even befor 2025 to compete with conventional energy applications.

Nordic region’s largest battery will assist 44MW hydropower plant as it balances the grid

Fortum announced that it will install the newest 5MW/6.2MWh battery energy storage system (BESS) at Forshuvud hydropower plant. It is one of dozens of hydropower plants Fortum owns and operates running off the Dalälven river’s catchment area through central Sweden. As with the Järvenpää battery, the Forshuvud battery will provide frequency regulation services. Forshuvud is a 44MW plant generating around 209.8GWh of electricity annually and is 88% owned by Fortum.

Conquer the battery sector together with cellution

 

We support you on tasks such as development of tender documents with detailed technical specification and requirements for your battery storage project or review offers you get from system integrators. It is a difficult task to have proposals comparable and identify, which is the best offer. We can help you with this challenge and support you even further with contarcts for product or performance. As you may know, a Li-Ion battery for example looses 20-30% of its capacity over the lifetime. Thats why it is important to have a warranty that covers this loss of asset to be able to plan your business accordingly.

Cellution can support you on a broad variety of tasks related to stationary utility scale battery storage projects and is looking forward to get in contact with you!
