The NASEO Energy Data Working Group brings together State Energy Offices, other relevant state agencies, and affiliate members to discuss energy data needs and gaps on the state and federal level. As states aim to meet growing electricity demands, they will require additional and more granular data that spans multiple sectors to allow states to evaluate power needs, reliability, and affordability, as well as track emissions and the integration of new energy resources. This working group will discuss available data, data needs, and develop guidelines for data sharing and data integrity standards for potential adoption by states.
