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.

National Grid has outlined how renewables could participate in the UK’s Capacity Market, unveiling technology-specific de-rating factors that range from 1–15%.
However National Grid’s Daniel Burke warned that there remains a long way to go before renewables can participate in CM auctions, not least because of the need for policy reform.
Any introduction of renewable energy into the CM would require regulatory overhaul from BEIS and market regulator Ofgem, matters which, Burke said, mean it is “quite feasible” to “take some time”.
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.

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.
