This year's Winter Storm Uri caused havoc in Texas, particularly in the energy sector, where extreme weather and a resultant set of generation problems and transmission grid issues led to loss of power and even loss of life across the US state. Ricardo F. Rodriguez, a senior consultant from analysis and research group Guidehouse looks at another aspect of the situation: the impact on the state's telecommunications infrastructure and how battery energy storage could provide a greater degree of certainty and resilience to this vital network.
Two standalone battery energy storage systems (BESS) totalling 200MW of output will be deployed in Texas’ ERCOT market by the energy division at Wärtsilä Corporation.
Texas’ grid and the idiosyncrasies of its electricity planning system regime made global headlines in February following a harsh winter storm and subsequent blackouts that affected millions of people and businesses for almost an entire week. It may be a unique market with unique characteristics, but what wider role can batteries — and other energy storage technologies — play in assisting the grid to remain stable and prevent a situation like this from happening again?
There has been growing uptake in battery energy storage in Midwestern US states that have traditionally depended on burning coal for electricity, with some “very big projects planned,” an analyst has said.
