Dive Summary:

• C3, a utility data management startup, is advancing a $150 million software platform that pulls data from grid sensors, databases, and even social media to peer into the grid and fight blackouts. C3 recently raised another $15 million and is quickly gobbling up partnerships with utilities.
• C3 worked with PG&E and GE to create a big data energy platform. The PG&E project crunched data about commercial and industrial buildings in the utility’s footprint, and helped PG&E work with these customers to reduce their energy usage.
• The startup will launch this type of project at five utilities in 2013 and another five in 2014. C3 customers include Entergy, Northeast Utilities, Constellation Energy, NYSEG, Integrys Energy Group, Southern California Edison, ComEd, Rochester Gas & Electric, DTE Energy and McKinsey.
