As the Workshop Chair, I would like to extend you an invitation to the Wind & Solar Integration Summit, presented by Infocast. Join me and my colleagues in sunny Scottsdale, Arizona as we gather with industry experts—federal and state regulators, representatives from ISOs, independent power producers, and pioneers in energy storage—to discuss the challenges posed by renewable energy integration and the opportunities for businesses that make the necessary adjustments to prepare for the 21st century grid. We will be kicking off the conference with a keynote address by FERC Chairman, Jon Wellinghoff.
This 3-day event will include a pre-conference workshop on the fundamentals of integrating variable energy resources and electric energy storage (EES), and will feature a presentation by Stoel Rives partner and Conference Chair, Stephen Hall. The conference will address issues and recent developments in integration, including market solutions and investments to facilitate renewable energy integration, changes to the regulatory landscape, and the role of EES in enabling increased renewables integration. Stoel Rives partners Ed Einowski, Bill Holmes, and Jennifer Martin will present on managing the risks associated with curtailment and integration issues in PPAs.
In case you need another good excuse to get to Arizona in January, Stoel Rives is currently offering a discount on registration. For more event details and registration information, please see: http://www.stoel.com/showevent.aspx?Show=7277.
Puget Wind Integration Charge REJECTED.
With a swift 13-page order today, FERC rejected Puget Sound Energy’s proposed wind integration rate, stating that the rate was not shown to be “just and reasonable” under section 205 of the Federal Power Act. “Changing system conditions, such as an increasing amount of wind generation described by Puget, present unique challenges that may require novel solutions. However, such solutions must fit the problems they are intended to solve, and the Commission must ensure that ratepayers are protected from rate proposals—such as the one proposed by Puget here—that are not shown to be related to the actual, demonstrable costs incurred in providing service.”
To determine the rate, Puget had used a proxy rate calculated using hypothetical capacity costs from a hypothetical generator. Puget chose its proxy from a group of five commercially available peaking units in the area. FERC stated that although it will allow for the recovery of legitimate and verifiable opportunity costs, Puget’s proposed rate was not a “reasonably accurate representation of the opportunity costs Puget incurs” in providing wind integration service. Because FERC cannot permit Puget to over-recover its costs in providing the service, the rate was rejected. Puget will undoubtedly be back to FERC with a rate that attempts to be consistent with FERC’s order.

BPA Issues Decision on Wind Integration Charge in 2010 Rate Case
Today, the Bonneville Power Administration (“BPA”) issued its Final Record of Decision (“Final ROD”) in the 2010 Rate Case. The Final ROD is part of an early wave of efforts by transmission providers to charge wind generators for the costs of providing “integration” or “balancing” services. Transmission providers are responsible for maintaining reliability of the transmission system. To do so, they must balance both loads (the electrical power consumed by customers) and resources (generation from hydro, thermal, or wind power plants) on their systems. BPA reserves part of its hydro resources so that if a large wind “ramp” event occurs, in which the wind output increases or decreases in a short amount of time, BPA can deploy its hydro reserves to keep the grid in balance. Before 2009, BPA did not charge a wind integration rate for providing such balancing services.
Background
BPA first proposed a wind integration charge in the 2009 Wind Integration Rate Case. This case was settled, with BPA's wind generator customers agreeing to a rate that was approximately four times lower than what BPA initially proposed in the 2010 Rate Case in exchange for BPA working toward the implementation of operational advances that would bring down the cost of providing wind integration services.
In its 2010 Rate Case Initial Proposal, BPA sought to charge its wind generator customers a wind integration rate of approximately $12 per megawatt-hour (“MWh”). BPA's wind generator customers argued that this rate would deter renewable energy development in the Pacific Northwest and make it difficult for the region to meet the Obama Administration's clean energy goals. BPA maintained that this charge was necessary, in part because the wind fleet had increased to such an extent that BPA feared it would be unable to provide enough reserves while also preserving system reliability. BPA argued that the increased size of the wind fleet was compounded by the wind generators’ inability to accurately account for wind ramp events in their schedules, thereby requiring BPA to hold a significantly larger amount of reserves in order to provide balancing services.
BPA's Decision
Once the wind generators on BPA’s system were made aware of their scheduling inaccuracies, they began taking steps to improve their scheduling. As BPA acknowledged in its Final ROD, over the next several months, BPA’s wind generator customers made significant improvements. Due in part to the wind fleet’s improved scheduling accuracy, the Final ROD sets the wind integration rate at approximately $5.70/MWh—less than half the rate in the Initial Proposal. This rate is subject to Federal Energy Regulatory Commission approval and varies somewhat depending on a project’s capacity factor.
The rate ultimately set by BPA has been criticized as not being cost-based, partly as a result of the way in which BPA allocated its embedded costs and its decision to also charge wind generators for lost "surplus" sales as a result of holding generation in reserve. BPA's wind generator customers argued that BPA's cost allocation violates Federal Energy Regulatory Commission policy. The wind generators also pointed out that BPA has been slow to implement the operational advances that would significantly lower the cost of wind integration. Despite the disparate views of BPA and its wind generator customers, the Final ROD echoes some of the arguments made by the wind generators in bringing the rate down from the initial $12/MWh and demonstrates a willingness by BPA to continue to work with the wind industry on improving its wind integration services.
Stoel Rives represented the Northwest Wind Group, a coalition comprised of Renewable Northwest Project and five major wind energy developers—BP Alternative, Columbia Energy Partners, enXco, Horizon Wind Energy, and RES America Developments Inc.—in this proceeding. We will be sending out an Energy Law Alert discussing the Final ROD and its implications for the wind industry shortly.

Show me the Money: $24 million Funding Opportunity for Wind Energy Research and Development
On June 2, 2009, the Department of Energy ("DOE") issued a Funding Opportunity Announcement ("FOA") providing $24 million for the development of consortia between universities and industry to focus on critical wind energy challenges.
DOE intends on awarding two to three grants of $8-12 million. The grants will be used to address two areas:
- Partnerships for Wind Research and Turbine Reliability. Universities in wind resource areas are encouraged to apply with industry partners to study major challenges facing today's wind industry. DOE is highly encouraging research in turbine reliability, but projects are eligible if they meet one or more challenges described in the 20% Wind Energy by 2030 report.
- Wind Energy Research & Development. Universities are encouraged to apply with industry partners for grants to fund R&D to advance material design, performance measurements, and analytical models related to wind energy development. The goals of this research shall be to improve power systems operations, wind turbine and/or component manufacturing, and interdisciplinary systems integration.
Applicants interested in either area must file a letter of intent by June 16, 2009 and FOA applications are due by July 29, 2009.
*****UPDATE******
On June 19, 2009, DOE announced an extension to the deadline for submittal of a letter of intent for this program. Letters of intent must now be submitted by June 29, 2009. Applications are due on July 29, 2009.
FERC Technical Conference on Wind Integration
From our colleague Jason Johns:
The Federal Energy Regulatory Commission will host a technical conference on March 2 to discuss the challenges of integrating large amounts of variable generation into wholesale markets and the grid. The Commission is also asking for innovative proposals that will help accomplish such large integration. Notably, the conference could hardly occur at a more appropriate time, as wind installation grew by 8,358 MW in the US in 2008 (more than gas-fired capacity) and certain regions of the country are hotly debating the costs of putting wind on the grid. Conference panelists will include Don Furman (Iberdrola Renewables), Brian Parsons and Brendan Kirby (National Renewable Energy Laboratory), Bob Kahn (Northwest & Intermountain Power Producers Coalition) and Steve Oliver (Bonneville Power Administration, which put its first wind integration charge in place in 2008).
