Gridworks’ mission is to convene, educate and empower stakeholders working to decarbonize electricity grids.  Since 2010, Gridworks (formerly known as “More Than Smart”) has enabled this mission through four strategies: by identifying high-value challenges to decarbonizing electricity grids; convening stakeholders and providing them neutral ground, technical support and facilitation to identify break-through solutions to identified challenges; publishing and helping implement identified solutions; and adapting successful solutions to new markets.

In 2018, Gridworks convened 60 discreet events with over 2,600 total participants leading to 5 major white papers and reports.  Sign up for our newsletter for regular updates on our progress in 2019.
