What about Standards?

October 12, 2011

Andres Carvallo, at Austin Energy as CIO,  led the build out of the first smart grid in the U.S. and worked closely with many interdisciplinary teams in selection, procurement, design, deployment, and operations.  He has some good points — Metcalfe’s Law

Glendale Power & Water has completed its initial roll out.  We should keep an eye on them.  See:  GWP Smart Grid Site

How Does Smartening The Grid Change Grid Work?

Governor Pat Quinn vetoed the Commonweath Edison’s Smart Meter Bill, as you can see in this Chicago Trib article — Gov. Quinn’s Veto

This comment was posted at Smart Grid News’ coverage of the event on 14 Sep by a Mr. R. Perry:  “Meters are important because they measure total usage, which is important for billing.  It would be great if a smart meter could provide the customer with ancillary services, such as Energy Efficiency (EE) and Demand Response (DR), which would indeed justify their cost.

“But they don’t and can’t.  Smart meters report total usage, but Energy Efficiency and Demand Response don’t care about total usage.  EE and DR care about current usage.

“And you can’t determine current usage without real-time telemetry, which means broadband.  The only way to effectively do EE and DR is to use devices that measure current usage for individual loads (e.g., with smart two-way thermostats) report it to servers, which then control these loads in real time.

“Further, EE and DR do not care about whole home usage.  They care about individual loads that can be individually controlled — which cannot be done using a smart meter.

“Smart meters and their corresponding AMI  networks, simply cannot deliver on the promise, no matter how much PR and marketing is done.

“Smart meters are already obsolete.  Welcome to the world of the Internet.

Governor Quinn as well as Mr. Perry are concerned about utilities directly charging rate payers for utility cost-savers instead of customer benefits.

The Power Grid Network delivers a comprehensive solution that includes both utility and customer benefits, without overwhelming either constituency with their capital costs.




Reliability Of The Grid — View from San Diego

September 19, 2011

“…The overloaded grid promptly crashed, causing blackouts to spread across the region and into Mexico. The lights did not come back on until the following morning.

The wind was blowing at only 8mph and the sky was partially overcast. So, California’s lauded sources of renewable energy were of little help.

If anything, they were part of the problem. Critics point out, with some justification, that California’s energy strategy of focusing on conservation and expanding intermittent sources of renewable energy—while ignoring the urgent need for more base-load generating capacity close to big cities—was the primary cause of the grid failure.

The wider issue is that the original voltage spike which triggered the monster outage should have been isolated at the Yuma substation in Arizona. …”  Reliability of the Grid
