Guideline released for Grid-Connected Energy Storage Systems

January 28, 2016 by Jeff Shepard

DNV GL has released the GRIDSTOR Recommended Practice (DNVGL-RP-0043). This independent set of recommendations combines all key standards and guidelines with credible industry experience and insights, to help guarantee the safe implementation and operation of energy storage systems for all stakeholders such as end users, manufacturers, investors or insurance companies.

The Recommended Practice is published eight months after DNV GL launched its GRIDSTOR Joint Industry Project, a global consortium for the energy storage sector working together to create a Recommended Practice. The Joint Industry Project has been pivotal in defining grid-connected energy storage and quality considerations that can successfully impact deployment.

As a technical expert with extensive experience in the renewable energy market, DNV GL was the catalyst in bringing international industry stakeholders together to speed up the process of developing a Recommended Practice. The Recommended Practice has been developed in cooperation with seven other parties consisting of technology producers, grid service providers, energy consultants and universities. Because of this, and by incorporating the insight, knowledge and authority of an additional 36 major industry players participating in the review process, the document answers the real quality needs of all stakeholders of grid-connected energy storage systems.

The GRIDSTOR Recommended Practice provides simple, clear and practice-based guidance on energy storage safety, performance and operation and goes far beyond any existing standards in covering the key quality criteria in those areas. Careful and unambiguous definition of relevant parameters, concepts and processes promotes clarity and understanding between stakeholders.

Addressing a broad range of energy storage technologies and applications, the Recommended Practice is aligned with on-going international standardization activities, based on globally accepted regulations and best practices such as IEC, ISO and IEEE standards. With a vast number of energy storage systems currently being deployed across the globe, and the absence of guidelines covering all relevant aspects on a system level as well as component level, the release of the Recommended Practice is well-timed.

DNV GL offers customers tailored support to ensure that their energy storage systems are compliant with the GRIDSTOR Recommended Practice. The new guidelines clearly define the life cycle phases of energy storage systems and corresponding activities as well as the scope of responsibilities for each player in the industry, allowing smoother processes, better relationships between those in the value chain and ensuring that all expectations are in sync with everyone involved.

Stephen Tordoff from GRIDSTOR Participant Energy Canvas: “With energy storage being so important for the transition to more renewables, the GRIDSTOR initiative is timely for the support of solid investment decisions in the development, deployment and operation of energy storage assets. ‎We're proud to participate with DNV GL and the consortium partners to deliver this relevant project.”

Nadina Baghina from GRIDSTOR Participant Joulz: “Energy storage has become one of the key elements of the electricity network to solve issues such as network balancing or congestion. As an experienced system integrator in The Netherlands, energy storage has been in our attention for the last years. There were limited shared practices about it and not enough standardization. This project was a great opportunity to learn from each other’s experiences and expertise. It resulted in a wonderful collaboration between various parties with different views on energy storage. We have been involved in several projects where we applied this knowledge and we further develop it to a new level.”

“At DNV GL we believe that actions such as the Recommended Practice supports the entire industry and global community by offering a single standalone, all-encompassing guideline,” commented Jillis Raadschelders, Head of Department Renewables & Storage , DNV GL. “By bringing together the most important and relevant standards and guidelines and combining them into one document, DNV GL and its consortium has managed to fill a gap in the industry to help our customers and partners maximize their possibilities, exceed their expectations and reach their regional goals for energy storage.”
