DNV GL has updated its recommended practice for grid-connected energy storage.

The Gridstor recommended practice incorporates the latest storage technologies and market developments and provides the “most up to date recommendations on safety, operation and performance”, DNV GL said. 


It added that Gridstor includes the latest industry guidelines on cyber security, communication protocols, microgrids, conformity assessment, warranty, decommissioning, tendering and procurement, bankability, residual value and greenhouse gas emissions calculation.

The recommendations, which have been updated by experts from 15 global organisations, combine all the main standards and guidelines, DNV GL said.

The organisations are the Alaska Center for Energy and Power, Alfen, Alevo, ATEPS, Conergy, Datawatt, DNV GL, Enexis, Gaelectric, Highview Power, Hybrid Europe, Maxwell, PNNL, RWTH and Wärtsilä.

More than 140 organsisations in the energy storage market also had input during a public consultation on the updates, DNV GL added. 

DNV GL Energy chief executive Ditlev Engel (pictured) said: “Gridstor provides the most relevant recommended practice allowing all stakeholders to safely develop the vital technological and system advancements using energy storage.”
