First Time in History that Solar Installations (36.5 GW) Greater than Wind Power Installations (35.5 GW)

Clean Edge predicting that solar PV will experience double-digit growth yearly and that by 2023 revenue growth in the PV industry will be $158.4 billion despite installed prices will continue to fall. The figure shows the projected gains in energy. Renewable Energy Trends 2013 to 2023

The Clean Edge report predicts an installed PV system price as low at $1.21 per watt by 2023. (maybe sooner) Clean Edge believes that in 2014 we will start to see “enlightened utilities begin to embrace distributed generation assets.” As rooftop solar continues its steady march towards adoption, utilities will continue to grapple with how to maintain healthy businesses in the face of declining electricity sales. “Some forward-looking utilities, if not fully embracing a distributed energy future, are making investments, forming partnerships, and acknowledging that the threat of DG might also be a business opportunity,” the report states. Clean Edge points to some examples of this that took place in 2013, such as Edison International’s purchase of SoCore Energy, a Chicago-based rooftop solar developer that does work in the commercial space. It also uses Duke Energy’s investment in Clean Power Finance as another example of utilities starting to think about profiting from distributed PV.

Could Minnesota’s “Value of Solar” Make Everyone a Winner?

Until now, those under TVA Green Partners program have been producing on-site energy from a solar panel has been treated much like any other activity reducing electricity use. Effectively the energy produced from solar is subtracted from the amount of energy used each month, and the customer pays for the remaining amount of energy consumed. The nations utilities are fearful of the financial effects of a reduced distributor income from the energy produced by solar. Increasing evidence suggests that the overall economic benefits to the utility’s electric grid may outweigh the loss of revenue. Xcel Energy, the Minnesota’s largest electric utility, shared estimations for the value of solar in its comments (to reduce the value) to the Public Utilities Commission in mid-February.

Value of solar to electric power distributors


The solar market price includes eight separate factors, but the largest four account for the lion’s share of the value: 25 years of avoided natural gas purchases, avoided new power plant purchases, avoided transmission capacity, and avoided environmental costs.
The value of avoided fuel cost recognizes that utilities cannot buy natural gas on long-term contracts the way they can buy fixed-price solar energy, and it internalizes the risk of fuel variability that utilities have previously laid on ratepayers.
The avoided power plant generation capacity value recognizes that sufficient solar capacity allows utilities to defer peak energy investments (like Xcel’s recently requested three natural gas peaking power plants that an administrative law judge discarded in favor of distributed solar).
Avoided transmission capacity costs rewards solar for on-site energy production, saving on the cost of infrastructure and energy losses associated with long-range imports.
The environmental value may be the most precedent setting, because it means that when buying solar power under Minnesota’s value of solar tariff, a utility is for the first time paying for the environmental harm it had previously been socializing onto everyone else. This value is based on the federal “social cost of carbon” as well as non-carbon externality values adopted by the Minnesota Public Utilities Commission. The preliminary market value of solar estimate by Xcel Energy (14.5¢ per kilowatt-hour) for Minnesota. Here in Tennessee we have a better solar exposure and can expect the solar estimate will be larger. The cost of electricity for the homeowner is now 10 cents per kilowatt-hour. The estimated levelized cost of energy from rooftop solar presently is between 16 and 20 cents per kilowatt-hour.
Distributors with their buying power can reduce the levelized cost of energy from solar. Interestly Best Buy in partnership with SolarCity that’s now coming out of its pilot phase, roughly 65 Best Buy shops in the U.S. now offer solar arrays to their customers. The company’s solar-as-a-service offerings allow homeowners to go solar with little or no up-front costs.

The Red Faces of the Solar Skeptics

For years, these critics — of solar photovoltaics in particular — have called renewable energy a boutique fantasy. A recent Wall Street Journal blog post continues the trend, asserting that solar subsidies take money from the poor to benefit the rich. this year the total photovoltaic capacity in the United States is projected to reach 10 gigawatts, the energy equivalent of several nuclear power plants. (By one estimate, photovoltaic costs crossed over to become cheaper than electricity generated by new nuclear plants about four years ago.)

Solar subsidies are dwarfed by historical taxpayer support of both fossil-fuel and nuclear-generated electricity. The International Energy Agency warns that continuing fossil-fuel subsidies contribute significantly to global environmental problems. The President has suggested that the 30% tax benefit for solar PV be eliminated or severely reduced. My reply is sure, when you remove all the subsidies for electric power of any type. Especially nuclear and fossil fuels.

To answer the critics that solar will depend on energy storage for it to be considered a dispatchable resources for electricity. Then why did TVA build one of the largest pumped stores before solar was on the horizon? It is simple, it is to balance supply and demand of electricity. it is the same reasoning for coal and nuclear plants where the plant says on line and the extra energy is sent to the store for use later. It is the same deal for solar.

An investment analysis by the financial services company UBS contends that an “unsubsidized solar revolution” has begun that could eventually supply as much as 18 percent of electricity demand in Germany, Spain and Italy. The report goes on to suggest that electric utility companies serving these markets may see their profits take a hit. The UBS analysts say that consumer-supplied solar electricity tends to reduce the spikes in electricity demand on the power grid (so-called peak load) from which these utilities have traditionally derived much of their revenue.

Apply now for 2014 Rural Energy for America Funding

solar farming2Farmers, ranchers and rural small businesses can apply now for grants and loan guarantees for clean energy projects under the Rural Energy for America Program – or REAP. REAP was renewed in the 2014 Farm Bill and supports a wide range of energy efficiency and renewable energy technologies, including wind, solar, biogas, biomass, small hydroelectric, geothermal, tidal, wave, and hydroelectric technologies.

An official notice of funding availability is expected in early April, with an application deadline 60 days later. This notice would be for funds from the 2014 appropriation plus funds carried over from previous years (total about $28 million). When the final REAP rule is announced, possibly in June or July, a second funding announcement will be issued for the 2014 mandatory funding ($50 million) from the new Farm Bill. Applications submitted but not funded in the first round will be considered in the second round.

Applicants should also be sure to check in early with the state staff of USDA rural development. They can answer questions, provide useful advice and may need to visit the project during the application process.

Natural Resources Defense Council calls for compensation for customers with solar PV

NRDC

The Natural Resources Defense Council and the U.S. utility industry’s trade group are jointly calling for a new rate structure to account for customers that generate their own power with rooftop solar systems. “We need the grid and need to improve it in ways that support clean energy and distributed resources,” says Nathanael Greene, director of renewable energy policy at the NRDC in New York. Owners of rooftop solar panels “must provide reasonable cost-based compensation for the utility services they use,” says both groups. In exchange, utilities must simplify the process of connecting systems to the grid and compensate owners “fairly for the services they provide.”

Under the current policy, known as net metering, utilities must purchase excess electricity generated by customers’ solar panels. Both groups want that policy to continue, with a new mechanism that would cover utilities’ fixed costs. Still, they agree that changes to utility rate structures would improve energy-efficiency programs and expand rooftop solar. They recommend allowing utilities to recover the costs of maintaining and improving the grid in a way that’s not tied to the amount of electricity they deliver to consumers.

“We want regulators to decouple grid charges from volumetric consumption,” Greene said. “Then the utilities can’t use net metering as an excuse for the high fixed-cost charges they want.”

Comment from S. Levy:
It is my personal belief that ratepayers are going to be supplied by smart metering in the near future. As a result of smart metering, the electric utility industry will begin setting different rates based on their peak loads during the day and evening hours. The purpose being to lower the peak demand that occurs between the hours of 5 pm and 9 pm. So, they will charge the consumer more during the peak hours to reduce the peak load and with it, the resources to produce and deliver that higher power level.

It’s all about demand charge management and that demand charge management can result in a 10 percent to 20 percent bill savings. That is if the homeowner controls the use of high wattage appliances and home electric heating and cooling of the home and their water heater. Automation is available today that can control these energy users.

Biggest Cost Reduction for Rooftop Solar Installations

According to a recent time-and-motion study of rooftop solar installations, the biggest opportunity for cost reductions are with integrated racking, and in eliminating the array of little nuts, bolts, wires, clips, pieces and parts that don’t add any functional value to the system, but still need to be assembled on the rooftop.

Obama Commits U.S. Federal Government To 20% Renewable Energy Target By 2020

Obama_in_Georgetown
President Barack Obama has issued a presidential memorandum directing the U.S. federal government to pursue a goal of deriving 20% of its energy from renewable sources by 2020. The document also instructs all federal agencies to take specific steps to better manage building performance, enhance energy efficiency and reduce energy waste.

The missive represents a follow-through on the president’s plan to counter climate change, announced in June. It directs agencies to achieve the renewable energy consumption target through a number of approved actions. The actions, in order of priority, are the following:

Installing agency-funded renewable energy on-site at federal facilities and retain renewable energy certificates;
Contracting for energy that includes the installation of a renewable energy project on-site at a federal facility or off-site and the retention of renewable energy certificates for the term of the contract;
Purchasing electricity and corresponding renewable energy certificates; and
Purchasing renewable energy certificates.
The memorandum sets a number of interim targets for renewable energy usage up to the ultimate 20% by 2020 goal. The first of these is a 10% target for 2015.

4 Factors Driving the Marriage of Solar and Energy Storage

A solar-powered microgrid demonstrates the potential of coupling big batteries with commercial solar. What if you could finance the energy storage equipment, much the way solar panels are financed, and the batteries provided a revenue stream? Modern grid-scale battery systems are only put in place to save money or provide services to the grid. An example is one installation that includes 402 kilowatts’ worth of solar canopies in the parking lot and, in a twist that differentiates it from most commercial solar projects, a shipping-container-sized battery from startup Solar Grid Storage. Here in Knoxville we have a battery enhanced solar powered car-charging station located at the EPRI location off Dutchtown Road. On a daily basis, though, the battery will deliver frequency regulation services to the local wholesale grid. By providing quick bursts of power to keep a steady balance between supply and demand, battery owner Solar Grid Storage will earn money that is normally paid to natural gas power plant operators.

Here are the factors that are driving the combination of commercial solar and energy storage.

1. The technology is there. Better batteries are in development that will lower cost.

2. The economics can make sense. AES Energy Storage, for instance, provides frequency regulation services at a wind farm in West Virginia, buffered by a 32-megawatt lithium-ion battery bank. Revenue comes from reducing demand charges by using stored energy during peak hours. Most of its customers are in California, which has subsidies for distributed energy storage. By contrast, the desire to have emergency power has become a priority in East Coast states hit hard by Hurricane Sandy and other severe storms.

3. Solar installers want storage — if it pencils out. Military bases and island locations that rely on diesel generators are obvious candidates. A battery can smooth out the flow of power that panels provide to the local grid and address issues, such as the drops in voltage that come when clouds pass over. Batteries could also enable solar installations in places, such as farms, which would have required costly upgrades to the grid infrastructure. The contracts to finance a combined solar and storage system are complex and need to become more standardized, as power purchase agreements are, said president Scott Wiater of Standard Solar. Financing these types of systems is still relatively new and developers need to find customers willing to try not only solar, but also relatively new energy storage technology.

4. NRG Energy Inc. and Exelon Corp.’s Constellation unit say interest in combining solar power with battery storage has soared in the year since Hurricane Sandy knocked out power to millions of homes and businesses on the East Coast. They are among more than a dozen solar providers that have introduced or enhanced in the past year systems that combine rooftop solar panels that generate power and batteries that retain electricity to use later.
People with solar-powered homes and businesses were frustrated to discover that losing power from local utilities also knocked out the inverters that connect rooftop panels to the grid, leaving them unable to tap the electricity they were producing. Adding battery storage solves that problem, said Tom Doyle, chief executive officer of NRG’s solar unit.

It’s also a growing threat to utilities.
“When Sandy came along we really didn’t have a product to keep solar power flowing during blackouts,” Doyle said in an interview yesterday at the Solar Power International conference in Chicago. “Now we can install systems that continue operating when the grid fails, and the costs are coming down.”
Battery storage can add more than 20 percent to the cost of a typical 10-kilowatt solar system for a four-bedroom home, Brendon Quinlivan, director of solar development at Constellation, said in an interview.
