The opening up of independent system operator (ISO) services as a result of FERC 841 has led to a “huge difference” in storage dispatch strategy for merchant markets with concurrent bidding now the typical strategy.
There is a perception that “batteries cannot be long life assets”, but it depends very much on how they are designed and used, Dr Marek Kubik of Fluence has said, in a video interview with Energy-Storage.News.
The UK government’s Department of Business, Energy and Industrial Strategy (BEIS) has refused to provide any clarity over when a decision on the potential de-rating of energy storage assets within the capacity market (CM) will be made despite a senior policy advisor stating the judgement is “imminent”.
The UK’s Solar Trade Association (STA) has refuted claims made in a recent report that a residential solar array in combination with an energy storage system was not “economically viable”, calling it flawed and lacking in detail.
There is no economic benefit from installing energy storage with solar PV in UK homes, a new study has suggested, adding that the cost of battery degradation would cost homeowners £400 (US$518) in the first year.
