The Electric Power Research Institute (EPRI) has announced a $1.8 million award from the U.S. Department of Energy (DOE) to develop and demonstrate new methods to operate power systems with high penetrations of solar.

The award is part of the DOE’s Solar Forecasting 2 funding program to advance predictive modeling capabilities for solar generation, says EPRI. Solar Forecasting 2 projects are designed to enable electric utilities to better manage the variability and uncertainty of solar power and improve grid reliability.

EPRI’s project, “Operational Probabilistic Tools for Solar Uncertainty,” will use solar forecasts to capture the uncertainty inherent in solar power output. Using actual data from three energy companies, the research will develop a platform that enables new power system operating methods and tools.

The project has three objectives:

  1. Develop improved probabilistic solar power forecasts for both utility-scale and distributed solar.
  2. Design advanced use cases for probabilistic forecasts through detailed simulation of power system operations for three energy companies.
  3. Develop and demonstrate a scheduling management platform that enables the integration of forecasts into operations.

“With improved solar probabilistic forecasts integrated into utility scheduling and reserve processes, utilities could improve reliability and reduce solar integration costs,” states Aidan Tuohy, principal project manager for transmission operations and planning at EPRI. “If successful, the research could help system operators better manage solar variability and uncertainty – not only for the three demonstration utilities but for the broader industry, as well.”

The three energy companies – Hawaiian Electric, Duke Energy and Southern Co. – offer diverse operating practices at various stages of solar installation and integration, including specific system characteristics such as the size of the region; current and expected solar penetration; daily and seasonal load shape; generation mix; and other factors, says EPRI. These diverse experiences with solar may allow for combined results from the project to provide a broad range of lessons for solar integration across the entire power industry – while providing specific results for the three companies.

Hawaiian Electric, Duke Energy and Southern Co. are providing an additional $760,000 for the project in the form of cost share, bringing total funding for the research up to approximately $2.6 million.

PRINEVILLE, Ore. — Facebook and Pacific Power said Wednesday they are teaming up to construct solar projects that will produce enough power to offset what the social media giant consumes at its data centers in Prineville, Ore.

The solar projects — two near Prineville and four in Utah — will generate 437 megawatts of power when completed by the end of 2020.

Data centers use large amounts of energy to run and cool the computers inside. The solar power for Facebook’s Prineville campus is roughly equivalent to the energy use of 100,000 Northwest homes. The company declined to say how much it will cost to build the solar projects or how the cost of the clean energy will compare to what it pays now, The Oregonian/OregonLive reported.

The companies along with Oregon Gov. Kate Brown announced the deal at an event in Prineville.

“This partnership bolsters Prineville’s 21st century model for a small town,” Brown said. “With projects like these, we continue to demonstrate that Oregon is ready for the clean energy economy of the future.”

Facebook, drawn by tax breaks, has three data centers in the Central Oregon community and is adding two more.

“It’s great to be seeing green energy development happening in places like Prineville,” Cesia Kearns, a deputy director of the Sierra Club’s Beyond Coal campaign, told The Bend Bulletin. “Pragmatically speaking, it’s the cheapest power option right now. Hopefully this will continue to be a trend Pacific Power will embrace.”

Thursday, July 19, is a great day for energy democracy.

On Buffalo’s West Side, neighbors are cutting a ribbon on a once-abandoned public school, and reopening it as a freshly renovated and energy-efficient building, partially powered by solar panels on the roof. School 77 now houses 30 units of affordable housing for seniors, meeting space for the community and offices for local nonprofits.

A few years ago, neighbors feared gentrification might claim the building. Instead, community members – low-income and working-class people of color – decided they wanted affordable, attractive, energy-efficient housing for the neighborhood. They wanted community solar power. They wanted a building that would serve the community. They joined forces with us at PUSH Buffalo, raised money, worked hard and delivered exactly what they wanted.

School 77 is a textbook example of energy democracy, which aims to advance equitable and sustainable economic development that includes everyone, regardless of how much they make or where they live, as we move to 100 percent renewable energy. The world is facing a new energy era. The technology for producing energy from the sun, the wind and other clean sources is getting cheaper and cheaper.

Renewables’ share of electricity generation is growing fast, while centralized fossil-fueled power plants are becoming less viable. In that energy transition lies opportunity, and it’s important to make sure that its benefits don’t just enrich corporations and utilities, but also flow to regular, everyday New Yorkers like the people behind School 77.

School 77 is also a great example of a community solar project. Residents can subscribe to power generated from the rooftop panels, and save money on their electric bills. Community solar offers a way for renters, low-income residents and others who don’t own a roof suitable for solar panels to benefit from the clean energy revolution. By joining community leadership with support from the state government, the City of Buffalo, nonprofits and businesses, School 77 has shown that community solar energy projects can work.

There’s one problem with School 77: It’s too rare. A state grant program to help community solar projects get started could help them proliferate. And a commitment to 100 percent clean, renewable energy could be a game-changer. Just think of all the vacant buildings and unused land, in Buffalo and across the state, that energy democracy could turn into productive community solar projects.

Gov. Andrew M. Cuomo’s Reforming the Energy Vision strategy rightly calls for building a clean, more resilient and affordable energy system for all. Community solar and energy democracy are key tools for realizing this vision. As we cut the ribbon on School 77, we hope for countless more ribbon-cuttings on projects like this one, in community after community, all across the state.

Rahwa Ghirmatzion is incoming executive director of People United for Sustainable Housing (PUSH) Buffalo.

A new study from Rutgers University New Brunswick could hold the key to boosting renewable energy and fighting climate change. Scientists have created a new method for producing hydrogen from water that is significantly more effective than previous methods. This technology could play a significant role in increasing the use of renewable energy and fight against some of the effects of climate change.

“Instead of using ultraviolet light, which is the standard practice, we leveraged the energy of visible and infrared light to excite electrons in gold nanoparticles. Excited electrons in the metal can be transferred more efficiently into the semiconductor, which catalyzes the reaction.”

Laura Fabris, associate professor in the Department of Materials Science and Engineering in the School of Engineering who led the work with Fuat Celik, assistant professor in the Department of Chemical and Biochemical Engineering

Gold nanoparticles shapes like stars are coated with a semiconductor. Once this happens the nanoparticles can use water to produce hydrogen over four times more efficiently than other methods. The researchers used a method of harnessing sunlight in order to make faster or cheaper reactions. This process is known as photocatalysis. Traditionally titanium dioxide illuminated by ultraviolet light is used a a catalyst; unfortunately, this method is fairly inefficient.

Scientists tapped visible and infrared light. This allowed the gold nanoparticles to absorb the light more quickly. Some of the electrons generated by the light absorption are then transferred to nearby materials, such as titanium dioxide. The gold nanoparticles were coated with titanium oxide before being exposed to visible, infrared, and UV light. Scientists discovered that as a result, electrons could produce hydrogen from water far more efficiently. The hydrogen could then be used to store solar energy. When the sun is not shining, the hydrogen can simply be combusted.

The results of this work provided scientists with a far deeper understanding of the mechanics of such technology. Additionally, the researchers were able to use use extremely low temperature synthesis to coat the gold particles with crystal titanium.

This research is far form over. The team of scientists is still investigating exactly how this material operates and interacts with others. Once the fully understand it, researchers will be able to create a variety of different materials with applications in an assortment of different fields. Scientists are confident that they can next convert carbon dioxide into a usable resource, which would increase the versatility of sunlight as a power source and help to combat the growing concern of global warming.

NORTH ADAMS — The city has seen the light: Its 3.5-megawatt solar array is producing enough energy to meet all its municipal electricity needs.

In North Adams, that has not come as a surprise to anyone who helped plan the array. But the fact that the 6,000-panel installation — it was built in 2015 and covers 14 acres on a capped landfill — consistently is producing beyond original projections has forced city officials to make a few adjustments.

After covering its own electric bills, the city is sitting on unused net-metering credits valued at about $200,000 that it hopes to unload on other municipalities, according to City Administrative Officer Michael Canales.

“It’s a good problem to have in that we can sell [excess credits] back into the market. … It is just a procedural challenge to work through,” said Mayor Thomas Bernard.

At current electricity rates, the landfill array results in the city saving about 25 percent on its annual electric bill, which is now budgeted at about $380,000 annually. The credits cover everything from streetlights to the city’s skating rink.

The savings are courtesy of the net-metering process that allows a solar installation like the city’s to feed the energy it produces into the grid and receive credits in return.

In the case of the landfill array, Syncarpha Capital covered the $9 million cost of installation. Per a 20-year purchasing agreement, the city pays Syncarpha for the energy that is generated by the array at a rate cheaper than the standard commercial rate.

Currently, the city is buying electricity at a rate of $0.099 per kilowatt-hour, compared with the commercial rate of $0.1475 per kilowatt-hour.

Though the savings are real, the city’s budget hasn’t always immediately reflected them.

Because the city agreed in 2015 to buy all the credits produced at its landfill solar array, it has spent more than $500,000 on its electric bill in a single year.

“Any savings we would have seen in the budget [last year] were evaporated by too many credits,” Canales said.

The excess has been consistent enough for the city to reach out to other municipalities in hopes of finding a new home for unused credits. It cannot sell the credits to private entities.

“It’s not as though it’s a seamless situation like the household where you just run your meter backward and [excess] goes out into the market automatically,” Bernard said.

The city recently sold credits valued at $20,000 to the Hoosac Water Quality District for $14,776.

One partner, Methuen Public Schools, has bought credits valued at $94,000 in the past. The city now is hoping to strike a deal with the Methuen school district to sell it $100,000 worth of credits every year.

For North Adams, these deals offer a chance to recapture the money it spent buying credits it won’t use. For the partnering municipality, the deal is a chance to save 25 percent on a portion of its electricity costs.

Though the credits never expire, city officials are wary of allowing them to accumulate.

The city also bought into two 650-kilowatt installations erected in North Brookfield and Westminster that account for about 85 percent of the school department’s electricity usage, according to Canales.

Fourteen solar-powered vehicles are racing 1,700 miles from Nebraska to Oregon as part of the American Solar Challenge.

The solar cars will loosely follow the path of the Oregon Trail to honor its 175th anniversary, as well as the 50th anniversary of the National Trails System.

Competitors from national and international schools have entered their vehicles, each built in a different style and using a variety of techniques. Some of the cars are single-occupant, while others are multi-occupant. All of them were built to last, and are proof that solar power is a reliable source of energy.

Watch the video above to learn about how some of the cars were built, and to see them in action.

SouthPoint Bank in Birmingham, AL has solar

Daily, it is estimated that over 100,000 people travel Highway 280. Many have likely noticed the highway’s newest neighbor, SouthPoint Bank, in place of the former Kobe restaurant. What they cannot see while driving is the solar power that SouthPoint Bank is harvesting. 

 

Eagle Solar & Light recently installed a 60-kilowatt solar system on the new bank. This system consists of two hundred and eight solar panels, or modules, and is designed to produce over 73,000 kilowatt hours of power annually. Solar power is not only good for the environment; it is also projected to save SouthPoint Bank over $10,000 per year on their utility bill. 

“When we began the design process for our new headquarters, we knew this building needed to not only serve our need for space, but also to better our efficiency. Early on we decided to incorporate modern,  to decrease our energy costs and make our contribution to environmental sustainability,” says SouthPoint Bank’s CEO Steve Smith. “At SouthPoint Bank, our goal is to look to the future and point forward with continuous improvement in technology. Utilizing solar energy within our corporate headquarters is one step toward achieving that goal.”

The solar panels selected by Eagle Solar & Light are produced in Jackson, Mississippi by Seraphim Solar. The use of American made solar panels defies the trend of using cheaper imported panels. Eagle Solar and Light trusts the quality of Seraphim Solar panels and backs their manufacturer’s 25-year warranty. Other American made components in this system are provided by SolarEdge and Snap’N’Rack.

“We were also able to meet our goal of supporting local companies by using a local contractor Eagle Solar & Light, plus using American solar panels rather than sourcing them from Asia,” says Smith. 

“Using American made products means a lot to us and our customers, and that is why whenever possible we source our products from American companies,” says Eagle Solar & Light CEO, Sam Yates. “We strive to meet the goals of every customer we serve.”

As one of the first solar companies to open in the central Alabama region, Eagle Solar & Light provides architecturally advanced, aesthetically designed solar electricity, LED lighting solutions and energy saving products that offer long-term economic benefits.

PRINEVILLE, Ore. — Today, officials from Pacific Power, Facebook, Crook County and the City of Prineville joined Oregon Governor Kate Brown to announce that Facebook’s Prineville Data Center will be supported by 100 percent renewable energy from new solar developments. This collaboration helps fuel Prineville’s growing data center industry, supports the city’s economic growth, and brings new cost-effective resources onto Pacific Power’s system while fulfilling Facebook’s long-term sustainability goals.

The Pacific Power and Facebook partnership will result in 437 megawatts of new solar developments, including two projects totaling 100 megawatts in the Prineville area. The joint effort puts Oregon and the City of Prineville at the center of a solution that both supports development of new renewable resources and provides economic development benefits for the state and local community.

“This partnership bolsters Prineville’s 21st century model for a small-town,” Governor Brown said. “With projects like these, we continue to demonstrate that Oregon is ready for the clean energy economy of the future.”

For Facebook, leveraging renewable resources to power its data centers and finding strong partners to help develop these solutions, have been a priority.

“Our work with Pacific Power to develop new solar resources represents a significant milestone for our hyper-efficient Prineville Data Center. We are committed to supporting 100{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} renewable energy, and we are thrilled to have found a solution for our first data center,” said Peter Freed, Facebook’s energy strategy manager. “We are proud to be a part of the Prineville community, and look forward to a continued partnership with the city and the state of Oregon.”

Since 2011, when Facebook opened the doors to its first data center in Prineville, the unemployment rate has decreased from 17 percent to 6.5 percent today. Along with job growth, stronger infrastructure has come to the area, including new roads, parks and an elementary school. Education benefits have come from grants, including support from Facebook, and upgrades to school curriculums, including more STEM education opportunities.

“We are expanding from our timber roots to a future with greater business diversity and a workforce with broader skills,” said Prineville Mayor Betty Jean Roppe. “It is through contributions and support from organizations like Facebook and Pacific Power, that Prineville is growing new jobs and strengthening our schools with programs that meet  the skills needs of tomorrow. This inspires new paths and opportunities for future generations, right here in town.”

As a company serving Oregon’s rural communities, Pacific Power seeks out opportunities to power innovation and ideas that bring strength to the cities and customers it serves and provide support for the future.

“At Pacific Power, we believe in the power of partnership. As a 100-year company with a long history of serving smaller communities across Oregon, we believe progress is best achieved when business and community come together,” said Stefan Bird, president and CEO of Pacific Power. “We view this partnership as a way for Facebook to meet its sustainability goals and for Prineville and its neighboring Central Oregon communities to grow and thrive, while delivering cost-effective resources to all of our customers.”
