Wind production during the second quarter was below normal across most of the western U.S. and Mexico, according to Albany, N.Y.-based AWS Truepower’s quarterly wind bulletin.According to AWS, winds were below normal across most of the western U.S., Mexico, India and the Philippines but above normal across most of Central and South America, Europe, and the Pacific Ocean and vicinity.Overall wind speeds across much of the U.S. rounded out the quarter well below normal – continuing the pattern from the previous winter, according to AWS, which notes that the Northeast through Midwestern and Appalachian states experienced higher-than-normal wind speeds through the quarter.As for Mexico, AWS notes that most of northern Mexico experienced winds less than 10% to 20% below the norm. Strongly above-normal wind speeds persisted to the south from the Yucatan Peninsula down through South America and into northern Brazil as well as the extreme south of the continent.

A silver inverter box in the basement of First United Methodist Church in Great Falls will take direct current from electricity generated by photovoltaic solar panels on the roof and turn them into alternating currents suitable for the power grid and powering the church.
Excess energy the system generates will cause the meter to spin backward, and NorthWestern Energy, the state’s largest utility, will purchase it from the church. Ken Thornton, an early backer of solar energy and the church’s building manager, led the project, with the PV panels installed in the summer. It will begin working next month.
“It’s funny, this is where they used to store the coal,” said Thornton one day last week, pointing out a nearby room where circles still remain on the ceiling indicating manholes where coal from wagons was once dropped into the facility and burned in boilers.
Power generation at the church is evolving thanks in part to net metering, a billing system in which surplus energy generated by a customer’s solar, wind or hydro-power system goes back on NorthWestern’s electric system with the customer receiving credit at retail rates. The 8-kilowatt rooftop solar system at First United will save an estimated $1,500 a year in energy costs.
Net metering has been around in Montana since 1999. It’s designed to encourage rooftop solar and other small renewable power generators that are easier on the environment. In Montana, customers of investor-owned utilities, such as the church can take advantage of it.
Expanding it to spur even more solar, wind and hydro projects at residences, farms and ranches, housing, businesses and even neighborhoods is a hot topic at the 2015 Legislature, spurred in part by the plummeting cost of solar.
“Renewable energy standards are kind of old hat,” said Kyla Maki, clean energy program director for the Montana Environmental Information Center, of the green power standards that dominated past energy policy discussions at the Capitol. “We’re now talking rooftop solar.”
The benefits of increasing net metering, Maki added, will go to the increasing number of people who are interested in investing in renewable energy systems on their property.
Some Republicans are joining conservation groups and companies in the renewable energy business in supporting an expansion of net metering in Montana.
“This is a freedom bill,” said Rep. Art Wittich, R-Bozeman. “It would allow for energy freedom, so you don’t have to buy power from a monopoly utility that decides how they are going to generate it. You can decided how you are going to generate your own power.”
Wittich is sponsoring a bill that would increase the allowable output of a renewable energy system eligible for net metering credits from the current 50 kilowatts to 1 megawatt.
Businesses that sell solar and wind systems see an opportunity to boost their businesses, create jobs and install more renewable systems at farms and ranches and multi-unit housing.
“You have to strike while the iron is hot,” said John Foster, a community wind specialist for Moodie Wind Energy in Great Falls, a subset of Moodie Implement, who sells wind and solar systems. “That’s really it. And net metering hasn’t been upgraded here in Montana since its inception.”
The legislation would provide incentive for farmers and ranchers to install larger systems that generate more power, making upfront investments more economical, Foster said. And allowing larger turbines will open up new geographic markets for him because they are more cost-effective even in areas with less wind, he said.
Foster also is a big supporter of a bill that would allow a customer generator participating in net metering to carry forward remaining unused kilowatt-hour credits from a solar or wind system and apply excess credits to separately metered accounts.
This bill is important to farmers and ranchers who often have several meters on their land for their home, out-buildings or water pumps for irrigation and stock water, Foster said. Right now, only a single meter can receive credits.
Efforts to expand net metering were shot down in 2013, Foster noted, but the “political climate is right” this session with more conservatives on board.
NorthWestern Energy, which has 345,000 electricity customers in Montana, sees the expansion as corporate welfare, said John Fitzpatrick, chief lobbyist for NorthWestern Energy.
Last week, Fitzpatrick told a legislative committee that net metering had grown to industrial proportions in other states with big box stores such as Walmart becoming the largest beneficiaries.
“Net metering is not a business plan,” Fitzpatrick said. ‘It’s a welfare program, and it’s the worst kind of welfare Democrats hate.”
About 1,200 residential and small business customers of NorthWestern currently have net meters, and the utility has been instrumental in the installation of net-metered systems in Montana over the past two decades, NorthWestern spokesman Butch Larcombe said.
“If anybody says we’re opposed to net metering, that just isn’t accurate,” he said.
Each customer of the utility pays a universal system benefits (USB) charge as a result of the original net metering legislation in 1999, he said, and that funding is used for a number of programs, including providing grants to those who install renewable energy systems, he said.
As a result, many of the people who have installed solar panels on their roof, or a wind turbine, are being subsidized by other NorthWestern customers, Larcombe said. Moreover, he added, when they use the electricity they generate to get a credit, it reduces what they pay to maintain the power grid even though they continue to use it, shifting the costs to other customers.
He also noted that NorthWestern is overpaying net metered customers because it buys the power at retail, which is a higher cost than the cost the utility would pay for the power on the market or the cost of generation.
A broader conversation is in order about the state’s net metering policy to make sure it’s fair to everybody, and that’s why NorthWestern opposes the legislation, Larcombe said.
Gary Wiens of the Montana Rural Cooperatives’ Association also brought up concerns about cost shift to a legislative committee last week.
Wittich doesn’t buy the cost shift argument.
Increasing the net meting cap means people could build larger renewable systems and get credit for them, he said. And ore people want to use solar at business, apartments, neighborhoods and residences, yet the criteria to take advantage of the credits is arbitrary, Wittich said. Right now, he said, only a fraction of the electricity produced in the state is “homegrown energy,” and that’s low compared to other states.
Wittich’s bill increasing the cap on the size of the home grown energy systems that could receive credits is just one of 10 or so bills aimed at expanding net metering in one form or another.
Based on lobbying for and against the bills, Wittich says net metering is among the top 10 issues of the legislative session.
The bill that would allow credits to be applied to separate meters is sponsored by Sen. Jennifer Fielder, R-Thompson Falls.
Fielder told members of the Senate Energy and Telecommunications Committee that she had taken an interest in homegrown renewable energy systems because they help Montanans become self-reliant.
“It promotes self-realization and energy independence for the little guy,” she said.
Mike Huber, a 45-year-old rancher who lives south of Great Falls, said he’s investigated putting up a wind turbine. But he’s refrained because right now he could only receive credits for one meter if he invested in a renewable system. But he has six meters alone at one address and “obviously I can’t afford to put a solar or wind generator at each one.”
He supports legislation allowing excess credits to be applied to additional meters.
Rep. Randy Pinocci, R-Sun River, is sponsoring legislation that also would increase the cap on the size of renewable systems that could receive credits in territories served by rural electric cooperatives.
Pinocci said he decided to take action in the Legislature because he wanted to put a larger wind turbine on his property, but couldn’t because of a cap under the current rules. He called the cap “a joke” because smaller turbines do not produce enough energy for farming and ranching operations to justify the investment.
“The bigger your wind turbine, the easier it is to pay for it, and the more money you make,” he said.
Renewable energy has been seen a Democratic issue, Pinocci said, but Republicans are getting involved now and he doesn’t care whether it’s a Republican of Democratic issue. In his view, limits on the size of renewable energy projects in areas served by rural electric cooperatives is discouraging investment in renewable projects in rural areas. Pinocci, a freshman, said lawmakers shouldn’t be influenced by lobbying from NorthWestern or rural cooperatives.
“If any representative votes against my bill, I believe the constituents are going to say, ‘No way, what you did was a mistake,’” said Pinocci.
Conservation groups such as MEIC, the Northern Plains Resources Council and renewable energy organizations are rallying the troops in support of the legislation. The Helena-based Alternative Energy Resources Organization, or AERO, put out an “action alert” about a hearing today in the Senate Energy and Telecommunications Committee about a bill from Sen. Mike Phillips, D-Bozeman.
The Montana Neighborhood Net Metering Act would allowed neighborhood energy facilities to connect to a utility’s distribution system. Businesses and individuals could then buy into the system.
First United Methodist Church installed the 8-kilowatt PV panels this past summer . In the future, Thornton hopes to put more panels up to increase the output to 25 to 30 kilowatts, which would cover the church’s yearly electricity bill of $5,000. The cost of the first phase was $15,000.
Over the past five years, the price of solar panels has dropped 80 percent as the result of the recession and competition from China, Thornton said. That and innovations in the manufacturing processes has resulted in less expensive and more efficient solar panels, he said.
“I’ve been doing this for 30 years,” said Thornton, 60, who holds a mechanical engineering technology degree from Montana State University. “So at this point, it’s becoming real economical to put solar panels on buildings.
The church’s roof sits at a 45-degree angle, and it faces south. The ideal slope for catching the sun’s rays in Great Falls is 47 degrees.
“Oh, it’s perfect, Thornton said.
The amount of electricity generation allowed under the current net metering system for NorthWestern customers is adequate, he said. The church does not need to install a larger system to meet its electricity needs, Thornton said. He wants to make sure Montana doesn’t lose the net metering it already has for residential and small commercial systems.
But Thornton supports the neighborhood net metering legislation, and the bill that would make it easier for net metering projects in rural areas.

North American Windpower: Alberta Breaks Wind Power Record, Then Does It Again

Alberta Breaks Wind Power Record, Then Does It Againin News Departments > New & Noteworthyby Joseph Bebon Tuesday July 29 2014print the content itemCanadian province Alberta broke its wind generation record not once, but twice, last week. Between 11 a.m. and noon on Thursday, July 24, Alberta produced an average of 1,188 MW of wind power. The province then surpassed that on Friday, July 25, peaking at an average of 1,255 MW between 9 a.m. and 10 a.m. Before last week, the previous record was set on May 29, with an average of 1,134 MW.Angela Anderson, a spokesperson for the Alberta Electric System Operator AESO, explains that the most recent records were due to a combination of very windy days and new wind farms. Specifically, she says the 300 MW Blackspring Ridge project, which went online in Vulcan County in May, “allowed the system to produce more wind than ever before.”According to the Canadian Wind Energy Association CanWEA, Alberta is home to over 1.4 GW of installed wind capacity and ranks third among the country’s provinces. Tim Weis, the association’s Alberta regional director, says the new wind production records are certainly noteworthy.“This is significant, not only because it was just this past April that Alberta broke the 1,000 MW plateau for the first time, but [also because] Alberta’s electricity system is showing that it can integrate large amounts of wind energy seamlessly,” states Weis.He also mentions that the AESO lifted a 900 MW threshold for installed wind capacity in Alberta in 2007, and now wind production has peaked at over 30% more than that original limit.Furthermore, it appears wind power is poised for growth in Alberta. “There is a lot of interest in wind development in the province, and that’s expected to continue over the coming years,” comments Anderson. She says the AESO currently has 15 active wind projects totaling about 2.1 GW in the grid operator’s connection queue.Overall, the AESO anticipates wind capacity to nearly double over the next 20 years from approximately 1.4 GW to 2.7 GW. “In fact, by 2034, we are forecasting Alberta will have more wind power than coal-fired generation on the system.”Nonetheless, Weis says most new power generation in the province will likely come from natural gas, not wind. “Alberta is facing two issues simultaneously,” he explains. “First of all, federal regulations require that coal units retire when they reach their 50th birthday. Alberta’s market is over 60 percent coal, and the first units will start to hit their 50th birthday this decade.“At the same time, Alberta’s system operator is forecasting significant growth in electricity demand over the next two decades, largely as a result of the growing oil sands industry. Several independent forecasts suggest that the vast majority of new electricity supply will come from natural gas to fill this gap.”Weis points out that the price of wind power isn’t the reason, though, as the AESO estimates wind energy within 7% of gas costs. The truth is, natural gas is simply easier to build in Alberta’s electricity market because “it can more easily bid into the market and respond to changes in future costs.”But there’s a problem: Weis says forecasts suggest a big switch to natural gas will eventually undo the environmental benefits gained from closing down coal plants, with greenhouse-gas emissions starting to increase again in just over a decade.Weis argues that although the AESO has proven it can handle more and more renewable energy on its grid, the province still needs “a new policy framework that recognizes the benefits of renewables so that we can continue to see wind grow in Alberta.”
