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

Stem Inc claimed to be on track to achieve its 2021 full year revenue guidance of US$147 million, after reporting a year-over-year increase in revenues of 245% for the first quarter ending 31 March.
The “artificial intelligence-driven clean energy storage services” provider mostly delivers energy storage hardware and software that businesses can use to lower their electricity costs, while Stem Inc can also leverage those systems to earn revenues from grid services or utility energy markets. Latterly it has also moved into the front-of-meter solar-plus-storage space, particularly in Massachusetts where the company commissioned a 9MWh battery system during the quarter.

20 May 2021: Mobile energy storage and power-as-a-service startup Moxion looks to replace generators in construction industry
Investors including Energy Impact Partners contributed to a US$10 million Series A funding round closed by Moxion Power, a US manufacturer of mobile energy storage systems.
Aimed at industries such as construction which rely on portable, outdoor power systems, Moxion believes its equipment, which customers will be able to rent, will help replace fossil fuel generators.
Generators using diesel and other fossil fuels do not just contribute negatively to greenhouse gas emissions (GHGs), they also create air and noise pollution which harm not only communities nearby but also the workers that rely on them.
