Case studies on integrating renewable resources.

Where wind integration has been most successful, state authorities developed and adopted basic transmission planning and cost allocation principles before FERC issued Order 1000. Experiences in Texas, California, and Hawaii demonstrate what it takes to overcome permitting and cost allocation barriers—namely, a coherent policy framework and close coordination among stakeholders.

The Best Little Nodal Market in Texas

Sweating the details for 2009.

The Electric Reliability Council of Texas (ERCOT) introduced wholesale market competition in 1996, following the organizational change of ERCOT from a pure reliability council to an independent system operator (ISO) the same year. This makes ERCOT one of the earliest adopters of competitive electric markets. Stakeholders and regulators in ERCOT are trying to work out the details of implementing this market.

Unintended Consequences

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.

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.
