FERC Order 890

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.

Bonneville's Balancing Act

In the Pacific Northwest, you either spill water or spill wind.

The wind power industry has been up in arms ever since the Bonneville Power Administration earlier this year announced its Interim Environmental Redispatch and Negative Pricing Policy. That policy, applicable during periods of high spring runoff and heavy water flow volumes on the Federal Columbia River Power System, calls for BPA to redispatch and curtail access to transmission for wind power generating turbines, and to replace that resource with hydroelectric power generated via BOA hydroelectric dams, in order to avoid having to divert water through dam spillways, which could threaten fish and wildlife by creating excess levels of Total Dissolved Gas (TDG), which can cause Gas Bubble Trauma. Yet the legal issue remains unclear: Does this practice imply discrimination in the provision of transmission service, or is it simply a matter of system balancing and generation dispatch? In fact, the FERC may lack jurisdiction over the dispute, as it pertains to the fulfillment of BPA’s statutory mandates.

California vs. Oregon

An expiring 40-year-old contract rocks the Pacific AC Intertie.

PacifiCorp informed FERC, PG&E, and the state of California that it would not renew the contract upon its long-anticipated expiration date of July 31, 2007. Instead, it would take back full ownership of its transmission-line rights and sell the available capacity into the open market under its own tariff at today’s going rate.
