Does anyone care about rising redispatch costs?
Regional transmission organizations (RTOs) or independent system operators (ISOs) dominate the major power grids of North America, with the notable exceptions of the Southeast and Pacific Northwest. The purpose of this article is not to criticize system reliability but to highlight the more pervasive challenge today and for the future: Controlling the cost impact of decisions by grid operators on energy market participants.
The industry must join a growing chorus in calling for new technology.
A growing movement to bring plug-in hybrid and all-electric cars to market has emerged, bolstered by the undeniable economic and national-security benefits that result from displacing gasoline with electricity. Also, our editor-at-large talks with Tesla Motors CEO Martin Eberhart.
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.
Congress renews PURPA’s call for conservation and load management, but the world has changed since the 1970s.
The “N-word” in the title first appeared in this journal more than 20 years ago, courtesy of the celebrated environmentalist Amory Lovins and his widely quoted piece, “Saving Gigabucks with Negawatts” (Fortnightly, 1985). Scroll forward a few decades. With restructuring of wholesale electric markets at FERC, plus formation of regional transmission organizations and independent system operators, the game was changed.
Financial data raises doubts about whether deregulation benefits outweigh costs.
Perspective
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:
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
While NAESB and NERC struggle over the issue, North America steadily drifts toward unreliability.
Time is running out. It's been more than two years since the North American Electric Reliability Council (NERC) Joint Inadvertent Interchange Taskforce (JIITF), on which I served, issued its white paper[1] proposing how to price the unscheduled power (inadvertent interchange)1 flowing between NERC-certified balancing authorities (BAs).
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
What construction cost might prompt orders for new nuclear power plants in Texas?
Electricity generation deregulation has opened U.S. wholesale electricity markets to unregulated power producers. In this uncertain environment, how should a generating company evaluate the risk of investing in new capacity?1
