Connecticut’s Senate has passed a bill targeting the deployment of 1,000MW of energy storage by the end of 2030, which when signed into law by the state’s governor will make it the eighth state jurisdiction in the US so far to introduce either a target or mandate for energy storage.
Senate Bill (SB) 952, ‘An act concerning energy storage,’ was passed by the upper house of Connecticut lawmakers on 20 May. The bill establishes goals, programme requirements and authority to procure energy storage and requires the state’s Department of Energy and Environmental Protection to report back to the legislative General Assembly’s Energy and Technology Committee each year, beginning 1 January 2023, on progress towards achieving those goals.

People that are sceptical of the ability to decarbonise the energy system are often simply not aware of the solutions that already exist. One major example of this is how the renewable energy and energy storage industries are rapidly adding digital capabilities to control how their resources interact with energy markets.
Smart software and artificial intelligence (AI) can forecast everything from how much electricity will be generated and when it will be generated, to the right strategies for putting that electricity into different market opportunities.
When Advanced Microgrid Solutions (AMS), one of the pioneers of adding digital capabilities to batteries, was acquired by energy storage technology provider and system integrator Fluence in October last year, it cemented a relationship between the two companies going back to 2019.

Standalone battery energy storage can potentially offer better value to the US electricity system than pairing batteries directly with solar or wind generation, but the pros and cons of each approach vary greatly from project to project.
This is largely because siting the resources separately means the optimum location where batteries in particular offer most value to the electricity network can be chosen, according to a new study from Lawrence Berkely National Laboratory (Berkeley Lab).
Battery storage is useful for mitigating the volatility that increased renewable energy penetration brings to electricity networks, but it does not necessarily need to be interconnected to the grid at the same point in order to do so. Batteries can also mitigate other problems that the grid experiences, such as transmission congestion, where demand for electricity is growing greater than the network infrastructure that
