Everyone is in favor of more demand response, but little gets delivered when system operators need it the most.
Scott Neumann, Fereidoon Sioshansi, Ali Vojdani, and Gaymond Yee
Despite overwhelming theoretical and empirical evidence, we aren’t seeing more DR when it is needed most—during emergency periods. The reasons boil down to two obstacles, both of which must be addressed before widespread DR implementation can move forward.
Using demand response to mitigate rate shocks.
In the minds of many policy-makers, DR has become associated with rate shocks, rate volatility, unpredictability, and loss of control over energy costs—the very things DR was designed to overcome. What can be done to change this?
A new law dampens coal-by-wire prospects.
Gary L. Hunt and Richard Lauckhart
A 2007 law essentially prohibits California utilities from signing long-term contracts for power, including those from out of state, unless they emit less than 1,000 pounds of CO2/MWh of electricity produced. While the law does not specifically bar coal-fired generation, the limit is set low enough to rule out all coal-power plants. A modern, highly efficient natural gas-fired plant barely would qualify. These measures, plus the new carbon-cap law going into effect by 2012, have sent utilities—large and small, private as well as municipal or city-owned—into a frenzy as they scramble to find alternatives to coal to meet their future demand.
(December 2006) Charles A. King, California ISO: “Kicked Off and On Schedule” reasonably captures many of the implementation issues and stakeholder concerns surrounding the California Independent System Operator Market Redesign and Technology Upgrade program. However, I was somewhat disappointed that the article offered few details about the benefits MRTU will provide.
Elimination of the utility must-purchase obligation can lead to unanticipated consequences.
The Energy Policy Act of 2005 adds a new section of the Public Utility Regulatory Policies Act (PURPA) of 1978. Section 210(m) of PURPA now provides for the termination of an electric utility’s obligation to purchase energy and capacity from qualifying cogeneration facilities if FERC finds certain conditions are met.

Incandescent light bulbs create a cogeneration benefit by warming the indoor spaces they illuminate.
Genuine price signals about the underlying cost of consumer energy usage are an important part of energy efficiency. With those signals, consumers can adapt to save high-cost energy, while making better use of available low-cost sources and supplies.
Cal-ISO files a new market design, but has it traded efficiency for software?
Eyeing a launch date of November 2007, Cal-ISO at last has come forward with plans for revamping its widely disparaged wholesale market design. The formal proposal, known as the MRTU (Market Redesign and Technology Upgrade), was filed this past February at FERC.

“The nature of a leader is that they set targets that you can’t accomplish by extending a ruler over the past track record in getting there.”
The models and motives behind tomorrow’s transmission expansion.
Major transmission projects based on two distinct models are showing signs of life. What can these projects teach us about future transmission investment?
