Alabama PSC Approves Renewable Energy Proposal

0

The Alabama Public Service Commission unanimously approved a proposal by Alabama Power to secure up to 500 MW of renewable generation over the next six years.

The plan provides options for the company to work with customers who’ve made renewable generation a priority while protecting other customers from bearing additional costs.

“This allows Alabama Power to offer renewables where they make sense for our customers,” said Nick Sellers, the company’s vice president of Regulatory and Corporate Affairs. “We are pleased that the Public Service Commission has reviewed and approved this filing. We look forward to working with those customers who have interest in more renewable energy.”

The company filed the proposal with the commission in June, and a public hearing on the plan took place in August. A number of organizations — including the Southern Environmental Law Center, the Southern Alliance for Clean Energy, the Alabama Environmental Council, JobKeepers Alliance, Alabama Industrial Energy Consumers, and the Gulf States Renewable Energy Industries Association — participated in the hearing. The state attorney general’s office also took part in the hearing.

Alabama Power devised the proposal following months of conversations with customers about the kinds of renewable options they would like to see, beyond the company’s existing hydro, biomass, and wind resources.

Under the proposal, the company can either build its own renewable projects or secure purchase-power agreements for renewable energy. Each project can be no larger than 80 MW, and the first project must be under construction within a year.

The commission approved the plan with some modifications. One requires the company to issue a request for renewable proposals every two years, beginning in 2016. Also added was a requirement that the commission vote on each individual project.

All the renewable projects will be reviewed by the PSC and the attorney general’s office and must provide positive economic benefits to all Alabama Power customers, such as putting downward pressure on rates.

Five hundred MW of solar can supply enough renewable energy to serve up to 100,000 homes during an hour of peak sun intensity on cloudless days.

Alabama Power has 1,600 MW of hydro resources across Alabama and 404 MW of purchased wind generation from projects in Kansas and Oklahoma. Alabama Power has the ability to resell the energy from its purchased wind generation and the associated renewable energy credits (RECs) — together or separately — to third parties to help keep rates low for customers. The company will have the same flexibility with qualifying projects under the just-approved renewables proposal.

Alabama Power customers already have the option to buy RECs, which represent the renewable energy attributes of energy the company is producing or purchasing. Customers can purchase RECs for as little as $1.25 per month. They can purchase as many RECs as they like — enough to match all their energy use or more.

Noel Cain, regulatory policy manager for Alabama Power, said during last month’s public hearing that renewables could help further diversify the company’s energy sources, giving the company greater flexibility in choosing the most cost-effective option for customers. Solar energy, for example, could potentially help offset higher-cost energy sources during the hottest part of the day. She also said that some renewables could potentially assist the company in meeting future mandates for reducing carbon emissions as proposed under the recently unveiled federal Clean Power Plan.

Amelia Shenstone from the Southern Alliance for Clean Energy praised the proposal during the hearing, describing the company’s goal of securing renewable projects that would help put downward pressure on rates as “excellent.”

Vestas Receives First Order from Xcel Energy for 200-MW Project in North Dakota

0

Vestas has received a firm and unconditional order in the U.S. for 100 V100-2.0 MW turbines to power the Courtenay wind power plant in Stutsman County, North Dakota.

The order, placed by Xcel Energy Inc., includes supply and commissioning of the wind turbines as well as a 3-year Active Output Management (AOM) 4000 service agreement, which delivers full-scope service to maximize turbine availability. Installation and commissioning of the turbines is expected in 2016.

The Courtenay project was originally developed by Minnesota-based Geronimo Energy and purchased by Xcel Energy in April 2015.

“We’ve been the nation’s No. 1 utility wind provider for 11 consecutive years, and we are pleased to partner with Vestas,” said Kent Larson, Xcel Energy’s executive vice president and group president of operations. “When complete, the Courtenay Wind Farm project will boast 100 Vestas turbines. This will generate enough electricity for about 105,000 homes, making use of North Dakota’s abundant renewable resource.”

“Xcel Energy is a national leader in wind power,” said Chris Brown, president of Vestas’ sales and service division in the U.S. and Canada. “We welcome them as a new Vestas customer and are confident our highly proven V100-2.0 MW turbine will ensure Xcel delivers clean, reliable power to their customers at a competitive cost.”

Siemens Creates New Sales Channel for Local Onshore Wind Energy Projects

0

Siemens is working to build stronger ties with owners of smaller onshore wind projects — the kinds of projects where local knowledge and expertise play a key role. In the future, Siemens will work more closely with partners on wind parks with up to three turbines. These partnerships will ensure that the operators of smaller onshore wind parks have access to local contacts.

Nadeva Wind GmbH, based in Glücksburg, Germany, is one of the first companies to participate in this new partnership opportunity. Partners take delivery of turbines directly at the factory and organize logistics and installation on behalf of the customer. Siemens will continue to offer commissioning and service. Further partnerships are currently being planned.

This new concept will allow Siemens to better meet the demands of many project owners in the German onshore wind market. The new sales channel for up to three wind turbines builds on the successful Siemens D3 product platform and incorporates standard components and proven tower configurations. Sales partners will offer logistics and installation independently. Customers can order project planning and permit authorizations as well as construction of foundations from companies like Nadeva Wind GmbH. This new distribution channel will initially be limited to the German market.

“Regional entities can act more flexibly in the market and they often have closer relations to potential buyers and customers,” said Thomas Richterich, onshore CEO of the Siemens Wind Power and Renewables Division. “With this new approach, we intend to gain customers who are interested in applying our technology in local wind projects. As sales partners, we will select local companies with extensive industry experience and close contacts to the customer base.”

Turbines will be Siemens-branded and will comply with Siemens’ high-quality standards. Therefore, every marketing agreement will be based on a detailed assessment.

New Atlas Could Help Wind Energy Sweep Across Great Lakes

0

By compiling meteorological wind data derived from several sources, Cornell University and the Technical University of Denmark scientists have assembled the first full observational wind atlas of the Great Lakes. The atlas bolsters the chances for developing wind energy in the region.

Accurate wind data lives in a disjointed and disjunctive world. The researchers have meshed these data to create a high-definition atlas using information gathered from weather stations, buoys, QuikSCAT (a NASA satellite that collects wind direction and speed data over water bodies), and satellites equipped with synthetic aperture radar (SAR).

“The techniques that we have employed optimize the strengths of each measurement type while allowing a longtime series of data to be combined with the exceptional spatial resolution of the satellites, corrected for gaps in data due to ice cover in the winter months, using a new algorithm,” said lead author Paula Doubrawa, a Cornell doctoral candidate in the field of engineering.

Doubrawa, her adviser Rebecca Barthelmie, who is a professor of engineering and a faculty fellow in Cornell’s Atkinson Center for a Sustainable Future, and others published, “Satellite winds as a tool for offshore wind resource assessment: The Great Lakes Wind Atlas” in the journal Remote Sensing of Environment in October 2015.

For years, scientists, economists, and environmentalists have touted the potential for wind-energy development in the Great Lakes region as it features a large expanse of exploitable wind resources. The lakes — touching eight states and two Canadian provinces — extend over 150,000 square miles, creating about 84 percent of North America’s surface freshwater and 21 percent of Earth’s total surface freshwater.

Wind resources are difficult to quantify accurately, according to Doubrawa. For example, surface ice formation during winter months precludes retrieval of wind speeds from satellites and warrants removal of buoys. Additionally, offshore observations are sparse, and sometimes wind data derived from satellite scatterometers (microwave radar sensors) and SAR may not be available either in time or at the required location.

“The compilation and analysis of these datasets is very time-consuming, and now the work has been done,” Barthelmie said. “Assembling this atlas and this kind of work helps agencies that plan wind farms or manage where wind farms will be located by identifying optimal locations.

“These maps can be integrated with other GIS-type databases — for example, mapping shipping lanes or recreational areas — to help plan where wind farms might be located as a balance between wind resource and existing constraints.”

In addition to Barthelmie and Doubrawa, the research is co-authored by Cornell’s Sara C. Pryor, a professor of earth and atmospheric sciences, as well as Charlotte B. Hasager, Merete Badger, and Ioanna Karagali of the Technical University of Denmark.

The research was funded by the U.S. Department of Energy (DOE), the National Science Foundation, and the National Renewable Energy Laboratory (NREL).
