Spark Power Corp., a Canadian energy services company, on July 4 acquired retail energy supplier Bullfrog Power Inc. in a move to expand its offerings to large energy users.

Bullfrog Power, founded in 2005, provides large consumers with energy from renewable resources. Its most-recent new customer announcement was in May, with Mirexus Biotechnologies, to supply the company with electricity sourced from wind and low-impact hydro resources and natural gas sourced from a methane-capture project at a landfill, for a factory, lab and office in Guelph, Ontario.

Spark said the combination of the two companies will allow it to offer "utility of the future" service that will include solar, energy storage, electric vehicle infrastructure and other energy efficiency technologies.

"The addition of Bullfrog to the Spark Power Group of Companies gives us an integrated capability and depth of expertise to deliver affordable and sustainable power solutions to the largest power users and utilities markets in North America," Spark Power Co-CEO Andrew Clark said in a news release.

Separately on July 5, Spark announced another acquisition, this time of Orbis Engineering Field Services, of Edmonton, Alberta. Orbis provides engineering and technical field services for power systems for the utility, oil and gas, mining, forestry and public sectors.

"Spark Power's mission is to deliver integrated, end-to-end power services that encompass our customers' entire electrical power infrastructure," Spark Power Co-CEO Jason Sparaga said in a news release.

Bullfrog and Orbis will operate as subsidiaries of Spark Power, retaining their brand names and respective management teams.
