ISGAN Smart Grid Glossary Online

The ISGAN Glossary is a project of the International Smart Grid Action Network (ISGAN), a multilateral collaboration between governments to advance the development and deployment of smarter electric grid policies, practices and systems.

The Glossary utilises OpenEI's collaborative, wiki-based platform to collect and organize definitions of smart grid concepts from a variety of high-quality international sources, and to make them freely accessible to policymakers and the public.
