National Grid Partners, the venture capital arm of a big utility provider in the northeastern U.S., has raised $150 million in fresh capital to invest in startups at the intersection of energy and information technology. The funding comes a couple of years after the Los Gatos, California-based investment division raised $250 million to try to disrupt the energy business before somebody else comes along to disrupt it. Of that amount, National Grid Partners has invested more than $227 million into 29 startups in about 30 months.
