Consumer Direct Energy Management is the Real Smart Grid Opportunity
Bottom Line –
Distribution grid automation will continue, at an accelerating pace. But for
those who can enable energy efficiency they have a market place today.
The energy industry is facing an uncertain future. According
to the International Energy Agency, worldwide energy demand will increase by
more than 50 percent by 2030. This is an opportunity for innovative
entrepreneurs. However, the huge sums being invested into Cleantech[1]
notwithstanding, technology invention in and of itself is not sufficient.
Rather, technology is an enabler of innovation. In many cases, the technologies
that may help solve energy and environmental issues are not new. What's new is
how mature technology, often developed for solutions in other industries, may
be used to generate tangible ...

Can the US Transmission Grid Support Renewables?
The power
transmission grid today is in reality three separate high-voltage
electrical transmission grids. These grids cover the contiguous 48 states and
parts of Canada and Mexico and are known as the Western Interconnection, the
Eastern Interconnection, and the Electric Reliability Council of Texas (ERCOT)
Interconnection. The three grids operate independently for the most part but
are connected in a few places by direct-current lines. All United States power
utilities, except those in the states of Alaska and Hawaii, are connected to
other power utilities through the national power grid. Dispatch centers
maintain and control the flow of electricity over the grid, supplying
electricity to meet the demand.
Little needs to be said about the
growing demand for ...

Why are Electric Cooperatives Good Opportunities for Private Wireless Networks?
The 864 distribution cooperatives are
an attractive opportunity for private licensed wireless networks. Together they serve
around over 14M power customers. They operate in excess of one
hundred billion dollars of assets, including 2.5 million miles or 42% of the
nations electric distribution lines, which is identically constructed as a
result of the conditions of funding put in place by the USDA's RUS in the
1930s. They deliver 10% of the total KwH sold in the United
States each year and also own mostly coal fired generation facilities to produce half of this
energy sold through 66 generation and transmission cooperatives.
Furthermore, they serve communities where the cost of
spectrum is relatively low and availability relatively plentiful. Finally ...

Should a Utility Own the Telecom Network that enables its Smart Grid?
Without a telecom plan the smart grid will become more complicated to
deploy and cost more to operate while enabling few of the uses of data
Google et al envision. It is therefore a critical first step for every
utility committed to a smart grid and a good candidate for every
investor looking for the investment at the epicenter of smart grid
deployments.
It is capital inefficient and dramatically complicates the purpose of the smart grid to utilize three different telecom networks , presented in the preceding post, or http://bit.ly/ScRAu provided by at least three different operators to effect the smart grid - in the home (HAN), distribution between transformer and meter (LAN) and electron carriage from substation to ...

What are Utilities Looking for from their Digital Grid Solution?
For most utilities the a smart grid investment
will:Improve resilience to attacks, natural disasters
and operator errors which in turn will result in near-zero wide-area
blackouts and greatly reduced local interruptions.Deliver High-quality power for sensitive
electronics and complex computer applications and the means to
differentiate the power and therefore bill appropriately.Give easy options for consumers to manage their
electricity use and costs.Enable the plug-and-play integration of
renewables, distributed resources and control systems. The implication is annual savings of tens of
billions of dollars from reduced interruptions, reduced congestion and
reduced need to build expensive plants and lines. Thus the distribution grid plays critical role
in the pooling of power sources broadened ...
