Black and Veatch has started work on four massive solar plants for Florida Power and Light, which will bring the utility to over 1.2 GW-AC of installed solar some time next year.

Today utility Florida Power and Light (FPL) announced the beginning of construction on four new solar projects spread across the state of Florida, which will total around 450 MW-DC of capacity when complete. Black and Veatch is building these projects as the engineering, procurement and construction contractor, and expects to have the plants put online some time in 2019.

• FPL Interstate Solar Energy Center, St. Lucie County
• FPL Miami-Dade Solar Energy Center, Miami-Dade County
• FPL Pioneer Trail Solar Energy Center, Volusia County
• FPL Sunshine Gateway Solar Energy Center, Columbia County

These follow four other projects of similar capacities which Blattner began work on last year.

The four new projects will each be around 112 MW-DC in capacity, and mounted on fixed-tilt racking, which FPL says offers a cost advantage. The utility notes that for projects of this size a variety of module suppliers are used, however Jinko Solar will supply at least some of the modules used, including some from its new Jacksonville PV module factory which is currently under construction.

Jinko Solar signed the world’s largest PV module supply agreement with FPL parent company NextEra in March, at 2.75 GW.

The plants will have a 1.5 DC-to-AC ratio, giving each one a 74.5 MW-AC rating. The company has not mentioned any plans to integrate battery storage at this time, but notes that it owns the nation’s largest solar-plus-storage project, and cites the benefits of solar and storage for improving the economics and operational flexibility of these projects.

This has also been cited by NextEra, which in its latest quarterly results call estimated that the including energy storage is adding an average of only 1.5 cents per kilowatt-hour to the solar and wind projects which it is building.

FPL currently owns or is buying power from 14 utility-scale solar projects. When this 298 MW-AC of solar is complete the utility will be at 1.233 GW-AC of installed solar capacity, and the utility expects solar to make up nearly 5{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} of its electricity generation by 2020. This is part of a boom of solar in Florida, which is currently the second-largest state solar market after California.

The company is doing this while reducing its already low customer rates. FPL notes that these projects are all being built at no net cost to its customers, and company spokesman Stephen Heiman estimates that FPL customers will save $40 million over the life of the projects.

With election season just around the corner, environmental advocates and local leaders gathered at the Dr. John W. Coleman Greenergy solar park to share ideas for accelerating Massachusetts’ transition to 100 percent renewable energy.

The 100{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} Renewable Energy Agenda, developed by the Environment Massachusetts Research & Policy Center, includes more than 30 policies that the winner of this fall’s gubernatorial election can implement to reduce energy consumption and rapidly re-power all sectors of the economy with clean energy.

“For decades, the Commonwealth has led the nation in preserving the environment, protecting public health, and reducing global warming pollution,” says Ben Hellerstein, state director for the Environment Massachusetts Research & Policy Center. “Now more than ever, Massachusetts must lead the way. With support from our state’s top leaders, we can power our homes, our businesses, and our transportation system with clean, renewable energy.”

Advocates described how Massachusetts’ solar and wind resources, combined with emerging
technologies like electric vehicles, air source heat pumps, and battery storage, will enable us to meet our energy needs with clean, renewable power at all times of the day and night.

After discussing the recommendations in the 100{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} Renewable Energy Agenda, local leaders
took a tour of the Greenergy Solar Park, which was built in 1981 as part of an initiative by
President Carter, it is the only installation from that period that is still operating. Since that
time, the park has added a wind turbine, and still provides energy for the adjacent Beverly High
School.

Fred Hopps, the director of the Coleman Greenergy Park, says, “Since 1981 the Photovoltaic site in the City of Beverly, known as Dr. John Coleman Greenergy Park, has been an historic technological monument to the durability and effectiveness of solar energy. Recently Beverly was one of the first cities to endorse the Pathway to 100{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} Clean Energy. The first step towards that goal is to develop as much solar capacity as possible. Renovating and upgrading Greenergy Park will continue the legacy as a beacon for the future of solar power.”

Speakers also pointed to the urgent need for action before the end of the legislative session. In June, the Massachusetts Senate passed a bill that would eliminate caps on solar net metering and increase renewable energy to 50 percent of Massachusetts’ electricity consumption by 2030 and 100 percent by 2047.

Last night, with just over 24 hours remaining in the legislative session, House and Senate negotiators agreed on compromise language for a clean energy bill. While the legislation takes some positive steps to increase clean energy, it falls short in other areas. In particular, it does not address caps on solar energy that are already holding back solar energy in more than 200 communities.

Jeff Cohen, a representative from Salem’s Sustainability, Energy and Resiliency Committee says, “Salem has been a clean energy leader, exemplified in our 100{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} Renewable Energy resolution, municipal aggregation program, and municipal solar investments. With all of this action, we know we need to work with our neighboring communities and we need statewide action to achieve a goal which is imperative for our environment, public health and our economy.”

A report by the Applied Economics Clinic found that increasing the renewable portfolio standard by 3 percent per year, along with other clean energy policies, would result in 600,000 fewer metric tons of greenhouse gases per year by 2030 (equivalent to taking 128,000 cars off the road) at little to no additional cost to the public.

Since 2007, Massachusetts has seen a 246-fold increase in the amount of electricity it gets from the sun. Wind energy generation in Massachusetts is set to increase dramatically in the coming years, with a commitment to install 1,600 megawatts of offshore wind capacity.

Massachusetts’ offshore wind potential is equivalent to more than 19 times the state’s annual electricity consumption. According to the National Renewable Energy Laboratory, rooftop solar installations alone could provide 47 percent of Massachusetts’ electricity.

“In Gloucester, the wind has always powered our economy. Historically, this was in the sails of fishing vessels, and now it serves as a source of energy for our town’s three wind turbines,” says Dick Prouty, of Town Green 2025. “Wind energy, and other renewable energy sources are the future for this state, and we are proud that Gloucester is a leader in this transition.”

Earlier this month, 16 academics, researchers, and clean energy industry leaders sent a letter to state officials affirming that “there are no insurmountable technological or economic barriers to achieving 100 percent renewable energy.”

“Now is the time for us to go big on clean energy,” says Hellerstein. “The legislation under debate today moves us in the right direction, but we need to go much further. Come January, we’re ready to work with whoever occupies the corner office on Beacon Hill to help Massachusetts go 100 percent renewable.”

A group of scientists from France, Russia and Kazakhstan has developed a fluorination technique which provided a significant efficiency boost to solar cells based on organic polymer material.

The team worked with polymer:fullerene solar cells, and found that the process of incorporating fluorine atoms into the polymer increased cell efficiency from 3.7{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974} to 10.2{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974}.

The researchers note that while this efficiency is still well below current commercial standards, the size of the improvement gained here demonstrates their potential: “Perhaps with further tweaks organic solar cells could outperform their polysilicon based counterparts,” says the release from  Moscow Institute of Physics and Technology, which participated in the study alongside University of Strasbourg, University of Lyon, Institut de Sciences des Matériaux de Mulhouse, Synchrotron SOLEIL in France, and Kazakhstan’s Nazarbayev University.

Their study, ‘Face-on orientation of fluorinated polymers conveyed by long alkyl chains: a prerequisite for high photovoltaic performances,’ Published in the Royal Society of Chemistry’s Journal of Materials Chemistry A, concludes that fluorination and ‘functionalization by bulky alkyl side chains’ are both necessary to achieve efficiencies above 10{0b7da518931e2dc7f5435818fa9adcc81ac764ac1dff918ce2cdfc05099e9974}, at least with the polymer being studied here.

The polymer was produced in a number of different configurations, and then its structure was again changed by adding fluorine atoms. According to co-author Dimitri Ivanov, the challenge was to “optimize solar cell efficiency by picking the right molecular energy levels of the donor and the acceptor, while also creating the appropriate supramolecular structure that would facilitate charge transport to the electrodes.”

DANVILLE – A new petition will be before the Danville Area Planning and Zoning Commission this week after some additional proposed changes have been made to the Danville Zoning Ordinance pertaining to solar and wind energy regulations.

The city has requested solar and wind energy systems be added to district use regulations in the zoning ordinance.

After additional resident and commission discussion after the city council sent the zoning petition back for further discussion, there were “only a couple small parts that changed,” said Danville Planning and and Urban Services Manager Chris Milliken.

For the section on solar energy, there are more clarifications on setbacks from any residential district. There must be a buffer or separation of 100 feet, Milliken said, which can include a type of screening such as landscape or fences.

A section also was added to address the quality of the solar panels, and meeting state and federal requirements in recycling or disposing of them if abandoned and no longer used.

Regarding wind energy systems, there is clarification to the height and how they’re measured, Milliken said. Language was added to refine the definition of small systems to ensure size is capped and setback distance from residences also is outlined.

At a recent city council meeting, commission members were appointed to serve on the newly reduced seven-member body.

Six returning commissioners are: Tracy Taylor, Katasha Butler, Ted Vacketta Jr, Adam Brown, Dale Carlton and Pete Goodwin. A new commissioner is Troy Savalick who works at Watchfire Signs.

The zoning commission also continues to talk about other possible zoning ordinance revisions and projects, such as downtown uses and parking, and agriculture zoning regulations.

Coming Up

The Danville Area Planning and Zoning Commission meets at 5:15 p.m. Thursday at the Robert E. Jones Municipal Building, 17 W. Main St.

ITHACA, NY (WSKG) – On Monday, NYSERDA, a New York State agency that works on energy research and development, announced a new tech product completely manufactured in the Southern Tier.

They’re made at Cameron Manufacturing and Design, a company out of Horseheads company and a Texas technology firm have created a new way to produce solar energy for industrial boilers.

Cameron employs about 230 people and expects to be hiring about twenty more over the next year, in part, because of this new project.

The solar arrays can reduce fuel costs by up to 80-percent. The first ones are going to a farm in Rensselaer County, in the capital region.

Arun Gupta is the founder of Skyven Technologies, the company that created the tech that goes into the arrays. He said they chose to manufacture in the U.S. because of costs and skills.

“It makes sense to manufacture here in the United States, and even here in the Southern Tier, for a few reasons,” Gupta explained. “One reason is shipping costs. The other thing is manufacturing expertise. The Southern Tier has tremendous manufacturing expertise in manufacturing. And that’s a big deal for us.”

The project got funding from 76West, a New York State contest that encourages new technologies to reduce greenhouse gas emissions.

(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.)

Darren Lipomi, University of California San Diego

(THE CONVERSATION) The energy-generating potential of solar panels – and a key limitation on their use – is a result of what they’re made of. Panels made of silicon are declining in price such that in some locations they can provide electricity that costs about the same as power from fossil fuels like coal and natural gas. But silicon solar panels are also bulky, rigid and brittle, so they can’t be used just anywhere.

In many parts of the world that don’t have regular electricity, solar panels could provide reading light after dark and energy to pump drinking water, help power small household or village-based businesses or even serve emergency shelters and refugee encampments. But the mechanical fragility, heaviness and transportation difficulties of silicon solar panels suggest that silicon may not be ideal.

Building on
others’ work, my research group is working to develop flexible solar panels, which would be as efficient as a silicon panel, but would be thin, lightweight and bendable. This sort of device, which we call a “solar tarp,” could be spread out to the size of a room and generate electricity from the sun, and it could be balled up to be the size of a grapefruit and stuffed in a backpack as many as 1,000 times without breaking. While there has been some effort to make organic solar cells more flexible simply by making them ultra-thin, real durability requires a molecular structure that makes the solar panels stretchable and tough.

Silicon semiconductors

Silicon is derived from sand, which makes it cheap. And the way its atoms pack in a solid material makes it a good semiconductor, meaning its conductivity can be switched on and off using electric fields or light. Because it’s cheap and useful, silicon is the basis for the microchips and circuit boards in computers, mobile phones and basically all other electronics, transmitting electrical signals from one component to another. Silicon is also the key to most solar panels, because it can convert the energy from light into positive and negative charges. These charges flow to the opposite sides of a solar cell and can be used like a battery.

But its chemical properties also mean it can’t be turned into flexible electronics. Silicon doesn’t absorb light very efficiently. Photons might pass right through a silicon panel that’s too thin, so they have to be fairly thick – around 100 micrometers, about the thickness of a dollar bill – so that none of the light goes to waste.

Next-generation semiconductors

But researchers have found other semiconductors that are much better at absorbing light. One group of materials, called “perovskites,” can be used to make solar cells that are almost as efficient as silicon ones, but with light-absorbing layers that are one-thousandth the thickness needed with silicon. As a result, researchers are working on building perovskite solar cells that can power small unmanned aircraft and other devices where reducing weight is a key factor.

The 2000 Nobel Prize in Chemistry was awarded to the researchers who first found they could make another type of ultra-thin semiconductor, called a semiconducting polymer. This type of material is called an “organic semiconductor” because it is based on carbon, and it is called a “polymer” because it consists of long chains of organic molecules. Organic semiconductors are already used commercially, including in the billion-dollar industry of organic light-emitting diode displays, better known as OLED TVs.

Polymer semiconductors aren’t as efficient at converting sunlight to electricity as perovskites or silicon, but they’re much more flexible and potentially extraordinarily durable. Regular polymers – not the semiconducting ones – are found everywhere in daily life; they are the molecules that make up fabric, plastic and paint. Polymer semiconductors hold the potential to combine the electronic properties of materials like silicon with the physical properties of plastic.

The best of both worlds: Efficiency and durability

Depending on their structure, plastics have a wide range of properties – including both flexibility, as with a tarp; and rigidity, like the body panels of some automobiles. Semiconducting polymers have rigid molecular structures, and many are composed of tiny crystals. These are key to their electronic properties but tend to make them brittle, which is not a desirable attribute for either flexible or rigid items.

My group’s work has been focused on identifying ways to create materials with both good semiconducting properties and the durability plastics are known for – whether flexible or not. This will be key to my idea of a solar tarp or blanket, but could also lead to roofing materials, outdoor floor tiles or perhaps even the surfaces of roads or parking lots.

This work will be key to harnessing the power of sunlight – because, after all, the sunlight that strikes the Earth in a single hour contains more energy than all of humanity uses in a year.
