Bluestone Energy Services LTD has moved into a new corporate headquarters in Norwell three times the size of their old Norwell space, in order to accommodate "recent growth and new hires."

The new space, at 136 Longwater Drive, is a continuation of the energy consultancy’s recent growth. In November, the company opened an office in Chicago, and in April Bluestone acquired Bedford-based Control Solutions.

Recently, Bluestone completed a sustainable facilities project and secured $600,000 in utility incentives for Dorchester’s Carney Hospital. The project will save the hospital more than $500,000 per year in energy costs, the company said.
