B2U Storage Solutions has further expanded its in-house second life energy storage project in California to 25MWh, an alternative approach to peers which president Freeman Hall explained to Energy-Storage.news.

PPA has been signed for a large-scale solar-plus-storage power plant by a group of Arizona municipal utilities and local authorities.

South African grid operator Eskom is close to finalising the launch of 832MWh of battery energy storage development, but eyes are on an even larger upcoming REIPPP-model procurement.

A solar-plus-storage microgrid being deployed at an alloys mine in South Africa will feature a vanadium flow battery energy storage system, using locally sourced vanadium electrolyte.

South Africa’s Ministry of Mineral Resources and Energy is conducting a fairly unique procurement programme for 2GW of energy capacity, to come from a “range of energy source technologies”. Clean Horizon head of market analysis, Corentin Baschet, spoke to Andy Colthorpe about what the “almost technology agnostic” tender aims to do and the type of companies and projects likely to be successful in it.
