Renewable energy has muscled its way onto the 2009 Legislature's agenda. As of Wednesday, lawmakers had introduced 16 bills to amend Initiative 937, the voter-approved 2006 measure that requires utilities to ramp up their purchase of solar, wind and geothermal energy beginning in 2012. The reason for the intense interest: This is the first session since its passage that the law can be amended by a simple majority vote.

If approved, I-937 would require the state's utilities to produce 15 percent of the their electricity from renewable energy sources, such as wind and solar power. Hydroelectric power, which supplies about two-thirds of the state's power, isn't included as a renewable energy source under I-937.

Chicago-based Invenergy Wind North America applied on Wednesday with Kittitas County to construct a $250 million, 69-turbine wind farm sandwiched between Vantage Highway and Interstate 90 southeast of the existing Wild Horse Wind Power Project on the east end of the county. ...By utilizing the county's pre-identified wind farm zone, the company will likely expedite the approval process. "I'm estimating that public hearings before the county commissioners on the project could come as early as December," Piercy said.

On Aug. 21, when afternoon temperatures in Washington state soared, Avista Corp.’s (AVA) utility division asked customers to cut their electricity use while it scoured the region for power supplies. Utility operators were frustrated, in part, because the company’s supply of wind power was producing nothing, thanks to a lack of wind. Avista wasn’t alone. Throughout the West during that August heat wave, a growing fleet of windmills met triple-digit temperatures with impotence. California’s grid operator was serving up a record amount of power that afternoon, too, while its 2,850 MW of wind turbines were churning out just 112 MW.......What can all these windmills do to help prevent a blackout in a heat wave? Utilities’ estimates of that range widely. When figuring out how to keep the lights on during the coming summer’s hottest day, PJM pencils in 20% of wind capacity for serving peak load. The California Independent System Operator figures 5% will be there. For Texas, which has more windmills than any other state, Ercot counts on just 2.6% of capacity. Avista, like many utilities operating their own grid, doesn’t count on any wind power during the summer peak. As more windmills come on line, overestimating could mean a blackout, while underestimating could mean paying a lot of money for unneeded standby generators.

Cost issues aside, Avista has no choice but to add new renewable sources of electricity to its portfolio. Initiative 937, approved by Washington voters in 2006, requires utilities to acquire new renewable energy resources or to buy so-called renewable energy "credits" from others so that they supply at least 15 percent of their retail load with renewable energy in 2020. I-937 requires utilities to meet biennial conservation targets beginning in 2012, and because wind-turbine farms take only about six months to build after construction begins, Avista doesn't have to erect its wind turbines right away, Silkworth says. "Our needs don't really start until 2012; so, we're not thinking of building this thing for a few years," he says.

Wind energy and hydropower have a see-saw-like relationship: When one goes up the other goes down. But the Bonneville Power Administration is hoping a small device that looks like a model rocket and weighs a few pounds can help ease the tricky synergy. BPA on Wednesday installed an anemometer to help the power-marketing agency better forecast oncoming wind at the Horse Heaven substation just west of Paterson.

The Bonneville Power Administration in the Pacific Northwest has run smack into an issue that may well be repeated elsewhere as wind power gains a larger share of the electric power generation mix. The issue is wind integration and, more to the point, how to manage operational and cost allocation issues that arise as wind power projects come into service. It also touches on public perceptions about wind and what role it can and can't play in meeting electricity demand.

A series of factors -- including increasing demand for wind farms, rising costs for materials and the weakening U.S. dollar -- have driven up construction prices. At the same time, Northwest dams don't have enough remaining flexibility to supplement and smooth the up and down generation patterns of new wind farms.

But partly because hydroelectric power is not included as a renewable resource in the proposed initiative's current form, several of the state's public utilities worry that the initiative could drive up costs and hurt rural economies.

The slogans are simple: Clean wind energy or coal-powered plants polluting the planet. Higher electrical bills or utilities free to save ratepayers money. In the muddle of initiatives and measures that clutter the Nov. 7 ballots, those for and against Initiative 937 are hoping to persuade voters with these basic concepts. But that’s only the tip of the wind turbine.

OLYMPIA, Wash. -- A coalition of conservationists and clean energy advocates filed an initiative Wednesday that would require Washington state utility companies to increase the amount of renewable sources in their electricity supply to 15 percent by 2020.

Congressman Doc Hastings told Gov. Chris Gregoire on Friday he's concerned that a final approval by her of a controversial wind farm in Kittitas County will set a negative precedent that says county government's wind power project review process is of no value. Hastings, a Republican from Pasco who represents Kittitas County as part of the 4th Congressional District, sent a letter Friday to Gregoire addressing his concerns centered on the Kittitas Valley Wind Power Project, a 65-turbine wind farm planned for 12 miles northwest of Ellensburg and sought by Houston-based Horizon Wind Energy. Hastings urged Gregoire, a Democrat, to consider "the potential implications of setting aside the lawful policies of locally elected officials - not only for future wind farm development, but also for power project siting in Washington generally," according to a news release and a statement from Hastings.

Increasing commodity costs, the weakening U.S. dollar and government mandates spurring demand all have driven up construction costs of wind farms, the Northwest Power and Conservation Council was told Tuesday. Costs for other kinds of power plants also increased, said Jeff King, a senior resource analyst for the council. In addition, representatives from two Northwest utilities and the Bonneville Power Administration reported that Northwest dams don't have enough flexibility remaining to supplement and smooth the intermittent power supplies generated by new wind farms.

Kittitas County on Wednesday charged a state council that makes decisions on county wind farms with being biased against the county's position and against public testimony from those in opposition to a local project and also alleged the council's chairman violated appearance of fairness rules. Site Evaluation Council (EFSEC) and governor-appointee, Jim Luce, prejudged the 65-turbine Kittitas Valley Wind Power Project before final decisions were made, was biased against the county's stance against the project and expressed disdain for public comment on the project. "Those disclosures ... are startling and undermine basic tenants of how we all believe government should operate," Zempel said in the release.

Looking east into Gilliam County and north into Washington, turbines are strung over ridgelines as far as the eye can see. And there are nowhere near enough of them. ...West Coast utilities and independent power producers are locked in a land rush to secure the best wind sites and the power they produce. Coupled with a worldwide shortage of turbines and a falling dollar, the resulting scarcity is driving up the cost of wind power, a burden electricity ratepayers will shoulder.

Sen. Maria Cantwell (D-Wash.) peddled a Democratic energy bill in her party's radio address Saturday despite the bill stalling over a dispute on renewable energy this week.

Formal adjudicative hearings by the state to examine the proposed Desert Claim Wind Power Project will likely begin the week of July 13 in Ellensburg, according to a tentative scheduled submitted last week. The schedule, including deadlines for pre-filed testimony and rebuttal of that testimony, was suggested to the state Energy Facility Site Evaluation Council, or EFSEC, during the council's day of meetings conducted Thursday in Ellensburg on the Desert Claim project.

The Desert Claim wind farm, planned by French-owned EnXco Inc. for eight miles north of Ellensburg, has been moving slowly since the company filed in November 2006 with the state Energy Facility Site Evaluation Council, or EFSEC, for approval of a scaled-back version of a project that was first sought directly from Kittitas County in 2003. Kittitas County commissioners in April 2005 rejected the older, 120-turbine Desert Claim version saying it wasn't compatible with the surrounding land-use in the project area. That decision was later upheld by a county Superior Court decision.

A clean-energy initiative on the November ballot promises to reduce the state’s dependence on fossil fuels, combat global warming and cut the cost of electricity. Backers of the measure, Initiative 937, also say new wind farms would generate millions in tax dollars for struggling rural communities. Can the initiative deliver on all those promises? It’s unclear.
