ERIC WESOFF: JULY 28, 2010
How about we start by calling storage, storage and a battery, a battery?
Utility-scale energy storage in the field today is limited to pumped hydro, a few large deployments using compressed air energy storage (CAES), hundreds of megawatts of sodium sulphur (NaS) batteries, mostly in Japan, and some experiments with banks of lithium-ion batteries, nickel-cadmium batteries and regenerative fuel cells (flow batteries). Greentech Media has long covered the energy storage market with technologies that include:
- Batteries (Li-ion, NiMh, Zinc Air, NaS, etc.)
- Flow Batteries
- Phase-change materials
- Thermal Storage as heat or ice
- Hydrogen systems
- Compressed Air Energy Storage (CAES)
- Pumped Hydro
- Superconducting Magnetic Energy Storage (SMES)
- Using off-peak wind energy to synthesize fuels More >

It’s easy to figure a strategy for surviving a tidal wave … run like hell for the high ground.
It’s more difficult to apply that thinking to the Smart Grid. We can see the wave is about to hit the shore… but which way is the high ground? Should a utility start offering all sorts of new energy services behind the meter? Or become a wires-only utility and leave the new services to others? Or compete with the EnerNOCs of the world? Or partner with them? Or emigrate to New Zealand to herd sheep?
Often guidance lies n the experiences More >

In separate stories, we’ve described how Cisco’s home energy management initiative reveals the underpinnings of the grid’s first operating system. And how Microsoft’s bureaucratic stupidity caused it to miss this billion-dollar opportunity.
I want to use this space to discuss the good and bad aspects of Cisco’s Smart Grid strategy from the utility point of view. Remember, I’m talking here about Cisco’s strategy, not about its current offerings, which still fall far short of the company’s long-term goals.
Let’s Start with the Good News
There is a lot to like about the idea of a standard operating system for the grid. For instance:

Cisco is one of America’s great companies. But that doesn’t mean it has a lock on creating thegrid’s first operating system. I see at least five challenges in its way.
Finding the right business model. Can Cisco really foist the cloud computing model onto utilities? After all, utilities make money by building and owning assets. Those assets go into their rate base, on which they earn a regulated return. And utilities notoriously prefer to have close control of all their systems.
Helping utilities find the right business model. Today, utilities are asked to spend

More than a year ago, I gave you an early warning of Cisco’s end-to-end smart grid strategy. Later in 2009, Tulane professor Geoffrey Parker stopped by with an important survival guide to the impending smart grid platform.
With the recent announcement of the Cisco home energy management solution, Cisco’s Smart Grid strategy is becoming ever more clear. The company describes its offerings as “an innovation platform.” I think you’ll get a better sense of its impact if you think of it as the grid’s first operating system.
In this article, I’ll quickly review the home energy offering. Elsewhere in this issue, More >
TUCSON, Ariz., Jul 14, 2010 (BUSINESS WIRE) — A surge in the popularity of solar energy systems has prompted Tucson Electric Power (TEP) to propose new, lower subsidies for residential customers who install photovoltaic (PV) arrays.
Nearly 1,100 local homeowners have reserved TEP SunShare rebates for PV systems this year, exceeding the total number of residential solar power systems completed over the previous nine years combined. Local businesses also have rushed to invest in solar power systems, draining the funds designated for up-front commercial incentives in 2010.
In response to this unprecedented demand, TEP has asked the Arizona Corporation Commission (ACC) to More >
