An integrated, two-way communications and networking platform is essential to the Smart Grid. The space is getting crowded as vendors see the handwriting (and stimulus money) on the wall. Those competing include major players in the wireless, cellular, and networking worlds. As you’ll read in this section, some vendors are partnering up to fuse complementary technologies that offer a bigger piece of the total solution.

On a fundamental level, the smart grid is the merging of two networks: the power network, consisting of the electrical generation, transmission, and distribution grid, and the modern communications network, which enables voice, video, and data communications for billions of endpoints around the world. As such, networking and communications technologies are at the core of utility smart grid deployments, and have been the focus of significant attention and fierce debate by industry players. |

As an ever increasing number of people around the world become connected by mobile communications networks, the challenges to providing electricity to these expanding networks are becoming greater as well. In particular, developing countries are seeing unprecedented growth in wireless subscribers, however many of the base stations in these areas are in remote locales that have limited or no access to grid power. Renewable energy from solar panels and small wind turbines offers a viable alternative to diesel generators in these remote off-grid sites, and a new report from Pike Research forecasts that renewable energy will power 4.5% of the world’s mobile base stations by 2014, up from just 0.11% in 2010. In developing countries, the percentage will be even higher – the cleantech market intelligence firm forecasts that 8% of base stations in those regions will utilize renewable power by 2014. |

Nothing is more crucial than getting Smart Grid standards in place, especially in communications. But the communications space is highly complex, both technically and politically. As our friends from EPRI explain in this exclusive report, we are getting down to crunch time. Different factions are drawing lines in the sand and different groups are vying to be in charge. The next few months could determine the direction of Smart Grid communications for years or even decades to come. |

Now that summer is here utilities and their customers are anxious to see the results of “smart grid” investments reflected in monthly bills. What they’re finding is that it doesn’t always take a multimillion-dollar subsidy or a high-tech smart grid for utilities to reduce their power usage and the associated costs. Sometimes it just takes a little imagination and a cell phone. |
