What about Standards?

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

Telling Comment:

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.

 

 

 

Brattle Group: Energy Efficiency in 2020

September 15, 2011

Energy Efficiency — 2020 – “Efficiency pessimists contend that energy efficiency (inclusive of demand response) is unlikely to make much of a dent on energy consumption and peak demand in the year 2020 since all the low-hanging fruit has been harvested. Ergo, the solution to meeting the nation’s future energy needs in a carbon-constrained future is to build more power plants (preferably those that don’t burn coal), transmission lines and distribution systems.

Efficiency optimists, on the other hand, contend that energy efficiency is essentially an inexhaustible well and we have a long ways to go before the bottom is reached. Their viewpoint suggests that enhancements in energy efficiency may eliminate the need to make investments in the power supply system, except for routine maintenance and upgrades.

And finally, efficiency realists contend that the truth is somewhere in between.
