CleanTECH San Diego, working with the City of San Diego, SDG&E, UCSD and its private sector member companies is working to quantify and categorize regional cleantech companies that touch smart grid technology development. Categories include solar energy, energy storage, energy efficiency, clean transportation and other technologies. CleanTECH San Diego has also created a baseline analysis of the direct and indirect economic impacts of the named clusters. This baseline analysis can help quantify year-over-year job growth and other economic impacts of the regional smart grid sector. This will be particularly helpful in measuring the economic impact of the over 180 solar companies and over 20 storage companies that call San Diego home.
