Enel Green Power North America (EGPNA) has agreed to acquire smart energy management services provider Enernoc for around $250m.

EnerNOC offers demand response and energy services for utility, commercial, institutional and industrial customers.

Under the deal, EGPNA will launch a tender offer to purchase EnerNOC’s shares at a price of $7.67 per share in cash, representing around 42% premium to its closing stock price on 21 June.

The acquisition will allow Enel to expand its demand response services, in addition to providing EnerNOC’s energy management technology and services to Enel’s existing commercial and industrial customers.

The acquired business will add Enel with around 8,000 customers and 6 GW of demand-response capacity, in addition to allowing to manage around 14,000 sites.

With operations in North America, Europe and Asia Pacific, EnerNOC also provides energy intelligence software that will allow businesses to enhance efficiency of the facility.

Its energy procurement tools and services enable customers to buy energy strategically, manage risk, and optimise pricing.

Subject to all regulatory approvals, the deal is expected to complete by the end of third quarter this year.

Enel global e-Solutions head Francesco Venturini said: "Enel's acquisition of EnerNOC, six months after our acquisition of Demand Energy Networks, reflects our strategic focus on the energy technology and services space.”
