DR & Conservation

When summer heat waves cause electric demand to peak, they also often cause wholesale electricity prices to rise substantially above their average levels. However, since most electricity customers face retail rates that do not reflect this movement in wholesale market prices, they do not modify their consumption patterns, causing a significant drop in economic efficiency. The Energy Policy Act of 2005 calls upon states and utilities to evaluate and implement DR programs to mitigate this problem.

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.

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?

Demand response reduces overall energy usage, but the magnitude of the reduction depends on whether the technologies are developed and deployed with efficiency in mind.

To turn efficiency investments into a growing revenue source, strong programs, in conjunction with effective monitoring and verification, are the keys to success.

Higher electricity prices have drawn sharp attention to the design of organized wholesale electricity markets—particularly to areas where residential customers’ rates will increase because multi-year rate freezes are ending. Some suggest changing the way that markets set wholesale electricity prices, or doing away with competitive markets entirely and returning to government regulation of prices. They say that the design of the markets exaggerates the effects of natural-gas price increases and unfairly rewards generators that use lower-cost fuels.

Advanced metering infrastructure (AMI) evaluations will benefit greatly from creating an appropriate DR portfolio as part of the overall solution.

In the Energy Policy Act of 2005 (EPACT), Congress sent a strong message to electric utilities, consumers, and industry regulators that they need to get serious about advanced metering, time-based rates, and demand response (DR).

To underline this point, EPACT states:

Some states, including Illinois, Oregon, Pennsylvania, and Texas, have been considering smart-metering questions as part of rate cases and resource-planning discussions. Other states, such as Kentucky, Louisiana, Ohio, and Virginia, have initiated EPACT Section 1252 inquiries separately from other proceedings. The tenor of the discussion also varies from state to state, with high-cost power states generally more attracted to AMI than low-cost states are.

Are the smart-metering provisions of EPACT 2005 a good thing? The answer, like most things in life, is, “It depends.” Looked at holistically, the opportunity is great. Viewed incrementally, it’s empty words on paper. It’s up to regulators and utilities to take the initiative.
