Hughes Network Systems, LLC ("Hughes") and Inmarsat Inc. ("Inmarsat") hereby submit these comments in response to the Department of Energy's Request for Information ("RFI") in the above-referenced proceeding. Hughes and Inmarsat are global leaders in providing satellite networks and services and satellite services, respectively. Hughes and Inmarsat, both global satellite communications leaders, have a long-standing commercial relationship and have worked together in various roles on a variety of satellite communications projects over many years, including in the area of Smart Grid projects. The companies submit these joint comments to explain the benefits and important role of satellite communications technologies for Federal Smart Grid Policy. For the reasons outlined below, Hughes and Inmarsat urge the Department of Energy ("DOE") to recognize that satellite networking technology will play a critical role in Smart Grid efforts for the utility industry and to ensure that, in developing communications requirements for Smart Grid, DOE and other federal, state and local government agencies develop Smart Grid policies that are technology-neutral and do not favor a particular communications or networking technology over another. Satellite technology options should be allowed to compete on an equal footing with other communications and networking technologies.
