BOULDER - General Electric Co. (NYSE:GE) announced Tuesday that it was making equity investments into three clean-technology companies, one of which is Boulder-based Tendril Networks Inc.

GE Energy Financial Services did not release the amount of its investments, which also included new stakes in Palo Alto-based SolarEdge Technologies Inc. and San Francisco-based GridNet.

The investment will help Tendril bring its smart grid energy-management technologies into more homes, Chief Executive Adrian Tuck said in a statement

Tendril's main product, the Tendril Residential Energy Ecosystem, or TREE, is an integrated software and hardware solution that enables two-way dialog between utility companies and their customers, allowing them to manage the consumption and supply of energy in smarter, more efficient ways.

"For its part, GE sees its relationship with Tendril as reinforcement of its ecomagination initiative, to help customers meet their environmental challenges," GE Energy Financial Services President and Chief Executive Officer Alex Urquhart said in a press release.  He added that there were "multiple commercial and technology development opportunities for collaboration" between the two companies.

Tendril and GE previously announced a partnership in July to develop software for connecting GE appliances to smart grid technology.

In June, Tendril said it received $30 million in financing led by VantagePoint Venture Partners, Good Energies, RRE Ventures, Boulder-based Vista Ventures and Appian Ventures.

The announcement of this new additional investment from GE came during a media event Tuesday morning at GE's Global Research Center in Niskayuna, N.Y.
