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.

Solar needs storage to compete in National Grid’s UK Capacity Market redesign

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”.

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.

Sharing batteries for grid services could net US$2,500 discounts for EDF’s UK customers

EDF Energy is seeking to build a portfolio of domestic batteries to take into energy services markets by offering discounted energy storage units to consumers via a new partnership with manufacturer Powervault. The pair is offering existing solar PV owners as much as £2,000 off the cost of a home battery system if they sign up to EDF Energy grid services. If taken up, this will allow the energy stored in a Powervault 3 battery to form part of an aggregated network that can be used to help balance the grid.

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!
