Connecting Electric Vehicles to the Grid
A sustainable transportation future will rely on innovative systems connecting vehicles, utilities, renewable energy sources, and buildings.
NREL is working with partners to develop electrified transportation systems that allow electric vehicles (EVs) to interact with the power grid, providing the opportunity to shift transportation energy demands from petroleum to electricity.
This animation depicts a potential future transportation scenario in which EVs are charged via electrified roadways (e-roadways).

Truck Platooning Delivers Fuel Savings

Semi-automated truck platooning reduces aerodynamic drag by grouping vehicles together and safely decreasing the distance between them via electronic coupling, allowing multiple vehicles to accelerate or brake simultaneously. NREL's initial test results indicate that platooning improves gas mileage at all speeds, but travel at 55 mph results in the best overall fuel economy. A number of conditions impact the savings, including ambient temperature, distance between lead and trailing truck, and payload weight.

Businesses Install Charging Stations for Workers' Electric Vehicles

Plug-in electric vehicles (PEVs) are playing a growing role in the country's transportation future. U.S. employers are recognizing that more employees are driving PEVs, and access to workplace charging can double a PEV driver's daily commuting range and bolster an organization's sustainability efforts. In addition, workplace charging can provide incentives to workers considering buying a PEV. To date, more than 160 employer partners have joined the U.S. Department of Energy's Workplace Charging Challenge, a program that aims to increase the number of employers offering workplace charging tenfold by 2018 and invites employers to pledge to provide workplace charging.

New Tool Helps Optimize Battery Lifespan

While upfront costs of lithium-ion batteries need to be dramatically cut for electric vehicles (EVs) to reach a wider audience, lifespan optimization and synergistic business approaches offer additional ways to make EVs more affordable. NREL's new Battery Lifetime Analysis and Simulation Tool (BLAST) suite makes it possible to predict long-term performance of batteries in a wide range of business strategy, use, and infrastructure scenarios—including fast charging, wireless charging, and battery swapping—and identify possible improvements. It has also been paired with NREL's Battery Ownership Model (BOM) to evaluate lifetime battery costs in conjunction with performance, longevity, and new value propositions.

Evaluation Focuses on Utility Vehicle Capable of Exporting Power to the Grid

NREL has teamed with Pacific Gas and Electric (PG&E) and Efficient Drivetrains Incorporated to evaluate the performance of a unique Class 5 plug-in hybrid electric bucket truck. The innovative utility vehicle is equipped with batteries and an electric generator that can export up to 120 kW of power—enough to power a neighborhood while repairs are being made by electric crews. NREL test results will help PG&E fine-tune the design of such vehicles and assist with expanding their use.

Offshore wind power means better business, better beaches | TheHill

The push by some politicians and the oil industry to expand offshore drilling to the Atlantic is the wrong way to create jobs and lower gas prices. In fact, offshore wind development off the East Coast could produce twice as many jobs and energy as offshore drilling while alleviating the risk of catastrophic oil spills.
Oceana's recent report, Offshore Energy by the Numbers, An Economic Analysis of Offshore Drilling and Wind Energy in the Atlantic, considered the amount of economically recoverable oil and gas in the Atlantic and made conservative estimates of offshore wind development to compare these two activities. We found that offshore wind development in the Atlantic would produce roughly 91,000 more jobs and could generate enough energy to power over 115 million homes in the next 20 years, which is almost double the job creation and energy potential of Atlantic oil.

NREL Reports Examine Economic Trade-offs of Owning versus Leasing a Solar Photovoltaic System

From NREL:


NREL Reports Examine Economic Trade-offs of Owning versus Leasing a Solar Photovoltaic System


Wednesday, January 21, 2015


Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.
The first report, "Banking on Solar: An Analysis of Banking Opportunities in the U.S. Distributed Photovoltaic Market," provides a high-level overview of the developing U.S. solar loan product landscape. The analysis covers the range of consumer and commercial loan products available for financing solar in the United States, discusses the potential and active market players in the distributed solar loan space, and provides qualitative and quantitative analyses of how solar loans of varying maturities stack up against third-party financing. Key findings include:
  • The levelized cost of energy (LCOE) for residential systems with solar loans was lower than the LCOE for residential systems with power purchase agreements (PPAs) by 19-29 percent (varying by the term of the loan), because of the higher cost of capital necessary for the sponsor and tax equity in a PPA transaction.
  • There are additional operational and financial risks associated with owning a solar asset, and many of the savings calculated depend on market environment and the specific situation of an individual homeowner or business. For example, changes in a homeowner's credit rating and the term of the loan can more than double the interest rate payments on the loan.
"Market interest rates on solar-specific loans currently range from 2 percent with special provisions to 8 percent," said Travis Lowder, an energy analyst and coauthor of the report. "Compare this to a weighted average cost of capital of 9-10 percent for third-party systems financed through tax equity investments. Using the lower cost rates provided by the loans could help to make solar power more affordable to more consumers, and more competitive with utility rates in more states."
The second report, "To Own or Lease Solar: Understanding Commercial Retailers Decisions to Use Alternative Financing Models," examines the tradeoffs between financing methods for businesses installing onsite PV systems. The authors present case studies of PV financing strategies used by two large commercial retailers that have deployed substantial PV capacity in the United States: IKEA, which owns its PV, and Staples, which leases its PV through PPAs. In addition to carrying out in-depth interviews with both organizations for the report, the authors analyze the considerations that influence any company's choice of PV-financing strategy using corporate and solar industry data. The report's goal is to clarify the economic and institutional costs and benefits of financing strategies and to inform other companies that are considering launching or expanding similar PV programs. Key findings include:
  • The LCOE for the modeled self-financed system is approximately 30 percent lower than the LCOE for the PPA-financed system, given a commercial customer's pre-tax discount rate of 10 percent; however the LCOEs are equivalent when the discount rate rises to 23 percent.
  • Companies may view the risks of ownership differently than those for a PPA-financed system. If a company assumed a 10 percent pre-tax discount rate for a PPA versus a 23 percent pre-tax discount rate for self-financing, then the LCOE would be 14 percent lower using the PPA.
"The most appropriate PV financing option for a particular business depends on the characteristics and circumstances of that business," said David Feldman, a senior financial analyst and lead author of the report. "A company must work across its different business groups to decide what is most appropriate for its situation. With that said, if a company has less expensive sources of financing and is comfortable with the risks, it can often save on its energy bills by owning a PV system."
The research was supported by funding from the Energy Department's Office of Energy Efficiency and Renewable Energy, in support of its SunShot Initiative. The SunShot Initiative is a collaborative national effort that aggressively drives innovation to make solar energy fully cost-competitive with traditional energy sources before the end of the decade. Through SunShot, the Department supports efforts by private companies, universities, and national laboratories to drive down the cost of solar electricity to $0.06 per kilowatt-hour.
