Electric Reliability Council of Texas (ERCOT)

Don't Mess With Texas

America’s energy competition laboratory prepares to build.

The ERCOT region remains a living example of how to make a successful transition to restructured wholesale and retail markets for electricity. At the same time, the market continues to witness some significant developments. Sights are turning from recovery to the next stage of the power business cycle: The Buildup.

An Expensive Experiment? RTO Dollars and Sense

Financial data raises doubts about whether deregulation benefits outweigh costs.

This year, U.S. electricity consumers will spend more than $1 billion financing the operation of six RTOs. RTO costs have nearly doubled since 2001. Restructuring the energy industry was more costly and more risky than anticipated, and reasonable estimates of RTO costs outweigh nearly all of the benefits anticipated.

How the filed-rate policy wreaks havoc- and what courts can do about it.

Like many venerable legal rules, the filed-rate doctrine is rarely questioned. Over the last century, it has served many important purposes. However, with deregulated wholesale electric power markets at the federal level and various degrees of deregulation across the states, both the doctrine's continued applicability and usefulness are suspect.

Transmission Upgrades: Who Pays?

Transmission Upgrades:

How to allocate the costs.

Efforts to establish and quantify congestion-reduction and loss-reduction projects are progressing in electric markets with locational marginal price (LMP) regimes. The Path 15 upgrade approval by the California ISO two years ago was largely based upon its economic benefits. A draft report from the Electric Reliability Council of Texas (ERCOT), , states that ERCOT will consider transmission projects that are "economically justified by the reduction of congestion and losses."1

Transmission Investment: All Talk and Little Action

Except for local reinforcements and new generation interconnections, few transmission construction proposals are moving forward.

Except for local reinforcements and new generation interconnections, few transmission construction proposals are moving forward.

There's plenty of talk about transmission, says Theo Mullen. "But real action on transmission construction is scant," he adds. "Conferences and reports abound. Projects of all sizes are being proposed. But, except for local reinforcements and new generation interconnections, few transmission construction proposals are moving forward. The vast majority of larger projects are stalled for lack of financial commitment."1

The CIO Forum: Budgets Byte Back

Chief tech officers discuss how they are using their data to beat the competitition.

This year's first IT commandment: Use what you've got. And the second is like unto it: Data is king. Those are the strong themes that emerged from this year's CIO Forum. Fortnightly interviewed three chief information officers at three diverse companies: a traditional utility, Cinergy; a merchant generator, Calpine; and an independent system operator (ISO), the Electric Reliability Council of Texas (ERCOT).

Winds of Change in Texas

Rising gas prices spark a rush to wind farms, straining grid capacity and raising larger issues about market design.

 


Rising gas prices spark a rush to wind farms, straining grid capacity and raising larger issues about market design.

When the Public Utility Commission of Texas (PUCT) was drafting rules to encourage the use of renewable energy, it took pains to guard against the chance that power producers would fail to reach the state's target of 400 megawatts (MW) in installed new renewable generation capacity by Jan. 1, 2002. The commission needn't have worried.

And in Texas, all customer information flows through ERCOT.

 

Texas thinks it has the right formula for retail choice.

When queried on the wisdom of its restructuring plan relative to California's restructuring woes, Texas likes to point to the new generation capacity coming online, and a supply-demand balance much more favorable than California's.

Pricing the Grid: Comparing Transmission Rates of the U.S. ISOs

How does each region manage congestion, allocate losses and dispatch resources? Which players gain the most from each approach?

The United States now has six independent system operators, five approved by the Federal Energy Regulatory Commission and one approved by the Public Utility Commission of Texas. These ISOs present an astonishing array of similar and conflicting rules and philosophies by which transmission services are defined and priced.

This article aims to explain some of the key similarities and differences among the ISOs' transmission pricing schemes.
