Project OverviewEnergy Storage ChallengeThe timely deployment of safe energy storage systems is complicatedbecause it is challenging to document and validate compliance withcurrent codes and standards, those codes and standards need to beupdated and new codes and standards need to be developedProject ObjectiveHelp with codes and standards updating and provide relevant materials toaid in documenting and verifying compliance with those documentsAccomplishmentsInitiated a collaborative work effort with stakeholders on the developmentof a guide focused on documenting and verifying compliance with currentcodes and standardsIdentified the need for three new standards, developed a purpose andscope for each and initiated collaborative work to draft criteriaIdentified a number of existing codes and standardsneeding revision and initiated efforts to helpupdate those documents

Purpose and Expected Outcome TodayPurposeEstablish a better understanding of the relevance andimportance of codes and standards (CS) to timely deployment ofsafe EES SafetyProvide information on the revision of current CS anddevelopment of new CS applicable to ESSProvide information on current CS deploymentExpected OutcomesRecognition that CS must be updated and available to guidetimely deployment of safe ESSKnowledge of current and future CS development activitiesHow to most effectively participate in those developmentactivitiesUnderstanding various means of deploying those CS4

Safety through Codes and StandardsEnergy storage and batteries are not newMany safety related issues are the same or similar to thoseassociated with other technologiesSome safety issues are unique to energy storage, in general,and others to particular energy storage technologiesCurrent CS provide a basis for documenting and validatingsystem safetyPrescriptivelyOn the basis of performanceCurrent CS provide a basis for documenting and validatingsystem safetyCS need to be updated to more effectively address the widerange of current and future ESS5

DOE OE Strategic Plan to Address ESS SafetyRelated IssuesLack of standardized validation protocolScience based testing protocols are neededValidation protocols must link the materials and celllevel to full systems integration into the gridKnowledge gained in testing and analysis must befed back to develop new safer materialsGrid Energy Storage SafetyIncident preparednessFire control systems, e.g. fire suppression materials,need to be identified for each storage technologyFirst responders educationPost-incident responseIncomplete and dispersed codes, standards and regulations(CSR)The CSRs for energy storage are dispersed throughout many sources(NFPA, IEEE, UL, etc.). Currently there is no central index of all CSR’sThe CSRs need continual updating due to rapid advances instorage technologies and new siting locations6

U.S. Codes and StandardsVoluntary sector standards and model code developersFederal, state, and local governmentadoption of voluntary sector standards and model codesimplementation and enforcement of adopted CSUtility, insurance underwriter, etc. adoption,implementation, and enforcement of CSThe need to document and verify compliance with thoseadopted CS directly and through the effortsof accredited third party agencies10

Examples of CS Development Processes11

Standards and Model Code AdoptionBy Federal, state or local legislative or regulatory actionApplicable in all areas covered by the actionMandatory maximum/minimumMandatory minimum with amendment allowedMandatory only if agency elects to adopt a codeBy insurance, builder, utility, etc. actionAs a criterion for participation in incentives or otherprograms (e.g. Medicare and Medicaid)As part of a professional practice – ethics12
