Australia-headquartered engineering and professional services company WorleyParsons said its first EPC contract for a battery storage project in the US shows how the energy sector is moving from “mega projects” to “portfolios of smaller projects”.

US state of Massachusetts recommends large-scale energy storage installations, sweeping policy changes, and wide-ranging pilot programme, a month after it proposes storage procurement targets for local utilities.

Massachusetts is to become the third US state, after California and Oregon, to impose minimum requirements for usage of energy storage systems.
