5 Startups Putting Wireless To Work for Energy

GigaOM readers are well-versed in both the wireless broadband networks that carriers are building and the Wi-Fi gear that we use in our homes, but what about the wireless technology that is starting to manage energy for the power grid as well as energy use within our homes? Sensor technology and wireless networks can provide disruptive innovations and increased transparency for the energy industry, enabling utilities to make the grid smarter and help consumers slash energy use.

Here’s our pick of five startups that are using wireless in innovative ways to change the energy landscape.

Eka Wireless: Eka is an eight-year-old company that develops wireless mesh networks to help utilities deliver energy conservation services. Eka’s wireless mesh networks use open, non-licensed spectrum and supply embedded nodes for so-called smart meters, digital two-way electricity meters that help utilities share price information with energy customers. The company is based in Maryland, has more than 65 employees and has raised $40 million in total from investors, FlyBridge Capital Partners, Angeleno Group, RockPort Capital Partners and The Westly Group.

EnOcean: This German company that was spun out of Siemens (s SI) in 2001 makes “battery-free” wireless sensor networks that use energy-harvesting technology and low-power radios to cut down energy use in buildings and homes. Sensors can do everything from detecting presence in rooms (i.e., shut off lights when not in use), to transmitting data about temperature, lighting and individual appliances throughout a building. EnOcean’s energy-harvesting technology turns tiny amounts of energy — from pressure, vibration and changes in temperature — into useable electricity for the network. The company has raised €20 million in funding from Wellington Partners, 3i Group, Emerald Technology Ventures, Siemens Venture Capital, Siemens Technology Accelerator, BayTech Venture Capital and ATMOS.

Ember: Ember, a company founded in 2001 and backed by Ethernet inventor Bob Metcalfe, makes the building blocks — chips, gear and software — of ZigBee-based wireless networks. ZigBee is a wireless standard that has gained a lot of traction for use in energy monitoring networks because the technology is low power, low bandwidth and low cost. Based in Boston, Ember has raised $81 million raised from Polaris Venture Partners, GrandBanks Capital, RRE Ventures, Vulcan Capital, DFJ ePlanet Ventures, DFJ New England, WestLB Mellon Asset Management (formerly West AM), ChevronTexaco Technology Ventures, Hitachi Corporation, Stata Venture Partners and MIT. Based in Germantown, Mnd., Ember has reportedly raised $40 million from the Angeleno Group, Rockport Capital Partners, Flybridge Capital Partners and The Westly Group.

SmartSynch: Smart meters are the connection between the utility and the power user. SmartSynch‘s technology uses makes current wireless networks, like cellular and Wi-Fi, to connect the utility to the smart meter. Using those networks is cheaper and faster to deploy smart-meter services, explains SmartSynch. The company has raised $80 million from Credit Suisse, Southern Farm Bureau Life, Battelle Ventures, Beacon Group, Endeavor Capital Management, GulfSouth Capital, Innovation Valley Partners, Kinetic Ventures, OPG Ventures, Nth Power, JP Morgan Partners, Siemens Venture Capital and Duke Ventures.

MMB Research: This small, young team of developers found they were consulting so much on ZigBee wireless networks and applications that they decided to create a company to sell ZigBee development software and services. As ZigBee has become the leading standard for home energy monitoring systems, more companies will have to learn how to develop for it. Why not get some help? The Toronto-based company is bootstrapped but says it could start looking for funding sometime next year.
