U.S. Military Sees Great Value in Distributed Renewable Energy

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/us-military-sees-great-value-distributed-renewable-energy/

There’s no better illustration of the value of distributed renewable energy than the U.S. military.  In Iraq, the 50,000 U.S. troops (as of August 2010) use 600 million gallons of fuel per year at a cost of dozens of lives of U.S. soldiers who die protecting fuel convoys and financial cost of nearly $27 billion for fuel and security ($45 per gallon!).  New distributed renewable energy systems can help combat brigades reduce fuel consumption, saving lives and money.

One Marine company – Company I, Third Battalion, Fifth Marines – field-tested the Ground Renewable Expeditionary ENergy System (GREENS) system in August 2010 and found that it saved 8 gallons of fuel per day for each of the company’s 150 men.  Complemented with other renewable energy systems, the Marines powered their combat operations center without using the diesel generator for eight days.

The renewable technology that will power Company I costs about $50,000 to $70,000; a single diesel generator costs several thousand dollars. But when it costs hundreds of dollars to get each gallon of traditional fuel to base camps in Afghanistan, the investment is quickly defrayed.”

It takes approximately 200 GREENS (1,600 kilowatts of solar modules with battery storage for 300 Watts of continuous power) to replace a single 60 kilowatt diesel generator, but it saved the Marine company 1,200 gallons of fuel per day.  In Iraq, that fuel would have cost $45 per gallon, including transportation and security costs.  That’s a savings of $54,000 in a single day.  If priced at $70,000 each, the 200 GREENS will pay back in 260 days, less than 9 months. 

If every U.S. company serving in Iraq made use of GREENS, it would reduce fuel consumption by U.S. troops by 25%, saving 146 million gallons of fuel and $6.5 billion per year. 

There are benefits besides saved fuel and money.  Marines appreciated that the solar-powered base systems are quiet, and also don’t require constant refueling.  The no-fuel requirement also benefits security, as 72 U.S. soldiers died protecting convoys in Iraq in 2009.

The military provides a great illustration of the utility and cost-effectiveness of distributed generation, and one that should inform state-side strategies for energy deployment.

New Montana PSC Commissioners Scapegoat Wind for Higher Electricity Costs, but Coal is Costlier

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/new-montana-psc-commissioners-scapegoat-wind-higher-electricity-costs-coal-costlier/

You can’t make this stuff up. 

Montana’s two newly elected Public Service Commissioners put out numbers, during their campaigns, purporting to show that electricity from renewable energy sources – specifically, wind – is more expensive than electricity from fossil fuels like coal.

Problem is, the truth is the exact opposite.  And these two people now regulate the electricity industry in Montana.  Kudos to citizen Ben Brouwer of AERO and the Billings News for getting to the truth:

Here are the comparative wholesale prices for electricity that [the state's largest private utility] NorthWestern Energy [NWE] acquires from different sources:

• Colstrip Unit 4 (coal): $56.05 per megawatt hour (MWh)

• PPL (mix of coal & hydro): $48.75 per MWh

• Judith Gap (wind): $29.25 per MWh, plus $8-13 per MWh for “integration” costs

• Energy Efficiency: $4.80 per MWh

Turns out the most expensive power acquisition for NWE is coal, with wind and energy efficiency being the least costly.

Feed-in Tariffs: a Renewable Energy Solution in an Era of Tight Budgets

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/feed-tariffs-renewable-energy-solution-era-tight-budgets/

Most states had to cut spending to close budget gaps in the 2009 fiscal year, and many face additional shortfalls in 2010. These cuts often mean shorter library hours and larger class sizes, but tax credits for renewable energy frequently emerge unscathed.

The cuts in government services tend to fall hardest on the middle and working class, while the energy tax incentives tend to benefit wealthier members of the community. The good news is that it doesn’t have to be this way. Wind turbines and solar panels don’t have to compete with schools and hospitals.

The fix is before Congress and many state governments, and it’s called a renewable energy feed-in tariff. It’s a “plug and play” policy for renewable energy, guaranteeing a grid connection to anyone with a wind or solar project, a long-term contract with your utility, and a price for electricity generation sufficient to make a small profit. It means that many more can be clean energy producers rather than just consumers, spreading the economic benefits of renewable energy over the widest possible area. A good feed-in tariff policy says, “It’s not just for rich folks anymore.”

Here’s how it works. A homeowner buys a solar power system and has it installed on her roof. The local utility connects it to the grid and signs a 20-year contract to buy her solar electricity. The price it provides will give her a small return on investment (say, 6 percent). If the homeowner’s electricity adds any cost to the system, the additional cost (amounting to pennies per month) is spread over all the utility’s ratepayers.

A feed-in tariff helped Germany get 16 percent of its electricity from wind and solar in 2010, with half its renewable energy systems locally owned, bringing economic benefits to every corner of the country. It did so at a lower price than other policy options, because having a guaranteed price lowered borrowing costs for renewable energy developers. And Germany didn’t have to argue for renewable energy tax incentives at the expense of health care, transportation or education.

A well-designed feed-in tariff can replace the maze of government rebates, grants and tax credits with the simple requirement that electric utilities pay producers for the full cost and value of renewable electricity. This strategy results in at least three significant benefits:

The policy can create a more democratic, decentralized electricity system because it removes most of the barriers to local energy generation. This dispersion of renewable electricity production will help maximize the use of the existing electrical grid (transmission and distribution). Locally owned projects return three times the economic benefits to communities that absentee-owned projects do.

The feed-in tariff also means transforming individuals from energy consumers to producers. Unlike traditional renewable energy incentives that target large-scale developments, the feed-in tariff lets anyone become a renewable energy producer. And when people make the shift from consumption to production, their energy use becomes a conscious effort to find equilibrium, rather than simply writing a check for the electric bill.

Finally, the feed-in tariff takes renewable energy incentives off the government balance sheet so that legislatures don’t have to choose between children and clean energy. It may even increase government revenues as hundreds of new renewable energy producers pay taxes on their electricity earnings. Furthermore, since these producers won’t be corporations with legal departments dedicated to reducing their tax payments, there will be more revenue per project.

State and federal budget problems recur regularly, but there’s no reason these shortfalls should pit energy independence and economic development against schools, libraries, or health care — especially when there’s a better solution for promoting renewable energy development.

This is an opinion piece I wrote this spring, published on Minnesota Public Radio’s website.

Economic Development is more than Electricity Prices

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/economic-development-more-electricity-prices/

The bottom line is that Frame and other critics of the plan seem to think that electricity policy alone is what determines the survival of Ontario industry. It’s an important component, but the price on a bill doesn’t reflect other programs and initiatives in place to help alleviate the economic strain. Sure, looked at in isolation it may seem scary, and it’s easy to criticize something in isolation of other facts, but it’s not constructive to the debate…

Historically there have always been U.S. states and Canadian provinces with lower — in some cases much lower — electricity rates. Have we seen a mass exodus of industry into Quebec, or Manitoba, or Wyoming? No, because electricity rates are one of many factors that are weighed by companies. Ontario is still very much competitive with many of the states that count, including Michigan and Pennsylvania, and we’re far cheaper than New York State, New Jersey and California. The claim that our industries are going to pick up and run is scaremongering.

Renewable Energy Economies of Scale are “Bullshit”

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/renewable-energy-economies-scale-are-bullshit/

I had a conversation with a wind developer yesterday and was talking about the difference between putting together large projects (over 80 MW) compared to distributed generation wind projects (80 MW and under).  I mentioned that we have a deep interest in understanding the economies of scale of renewable energy projects and he replied, “economies of scale are bullshit.”  He noted that large wind projects require significant development costs that smaller projects don’t encounter (including many more landowner negotiations and permits) and that installation and maintenance services are sufficiently widespread for any sized project to find services. 

It’s not entirely true that bigger projects have no economies of scale, but these two charts illustrate the larger point: Most economies of scale in solar PV and wind power are captured at a relatively small size.

The first chart is from the California Solar Statistics website, and draws on data from over 70,000 solar PV installations in California since 2005. 

Clearly, solar PV installations of 10 kW have captured more of the economies of scale for solar PV.  Costs may fall slightly for much larger projects, but the smaller number of projects makes it hard to see trends (interesting note: there seem to be as many > 100 kW solar projects costing over $10 per Watt as there are under $8 per Watt).

The second chart comes from the 2009 Wind Technologies Market Report by Ryan Wiser and Mark Bolinger (which is a must-read). 

The wind data is even more striking, with the lowest average project cost found in the projects with just a handful of turbines (5-20 MW of capacity), with costs steadily rising for larger projects.  Certainly there’s an advantage to having more than one turbine, but less so for growing the project much larger than 10 turbines. 

This data should inform renewable energy policy.  If modest-scale, distributed renewable energy projects capture most (or all) economies of scale, then the opportunity to place these projects close to load may reduce the need for new, long-distance, high-voltage transmission lines.   It means more renewable energy can come online faster and with fewer political battles. 

These smaller-scale projects are also the appropriate size for local ownership (which provides twice the jobs and 1-3 times the economic impact of absentee ownership), allowing more the economic benefits of renewable energy development to accrue to the host community.

Provincial Feed-in Tariffs Spurring Community Power

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/provincial-feed-tariffs-spurring-community-power/

With its feed-in tariff, the Canadian province of Ontario is set to become the leading community renewable energy center in North America. 

In an Oct. 12, 2010 report, [Ontario Power Authority] said that it has signed contracts for 264 megawatts of community-owned projects, and another 120 megawatts of projects owned by Ontario’s aboriginal peoples. The contracts represent 16 percent of Ontario’s 2,500 megawatts of feed-in tariff contracts to date.

No other jurisdiction in North America has made such a concerted effort as Ontario has to guarantee that a portion of the new renewable generating capacity to be built will be owned by its own citizens and native peoples through the province’s innovative feed-in tariff program.

This is in addition to Ontario’s microFIT program (a small renewable energy project program under the umbrella of feed-in tariff programs), which assures connection for homeowners and farmers wanting to generate electricity with solar panels for sale to the grid. There are 20,000 applications for microFIT contracts.

It’s noteworthy that despite Ontario’s success, Europeans still have significant leads based on their longstanding feed-in tariff policies.

…One-half of all wind generation in Germany, or more than 12,000 megawatts, is owned by local investors. The percentage of local ownership is even higher in Denmark and the Netherlands.

But North Americans are learning.  Vermont recently adopted a feed-in tariff, and the several other U.S. states and the Canadian province of Nova Scotia are also considering it.

Nova Scotia begins hearings Nov. 8, 2010 on the province’s community feed-in tariff program. The Nova Scotia Utility and Review Board will determine feed-in tariffs for large and small wind, biomass, and tidal power that will go into effect on April 4, 2011. Projects in the 100 megawatt program are set aside for Nova Scotians.

Public Utilities Finding Smart Grid Success

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/public-utilities-finding-smart-grid-success/

While there have been prominent news stories of smart grid cost overruns and customer dissatisfaction with programs run by investor-owned utilities, municipal utility smart grid programs are enjoying success.  Earlier this week, Public Power Daily featured three municipal utilities whose smart grid efforts are paying off

In two cases, city-owned fiber optic broadband networks are providing crucial information and revenue to support the smart grid.  In every case, customer satisfaction ranks much higher than rate of return on investment (although every investment will pay back).

EPB, the municipal utility serving the Chattanooga [Tennessee] area, is close to completing its rollout of a fiber optic system that will make the utility the first Internet service provider in the nation to offer 1-gigabit-per-second service (see the Sept. 16 Public Power Daily)…the utility is preparing to install new reclosers on its distribution system that will use its fiber optic network to measure current and voltages, locate faults and open and close switches…The IntelliRupter reclosers and software made by S&C Electric Co. “will play a critical role in helping us reach our goal of a 40% reduction in customer outage minutes,” Wade said. Based on an Energy Department study, outages cost Chattanooga an estimated $100 million a year, he said…The information gathered by the new reclosers should help with transformer load management, cutting down on transformer maintenance and allowing the utility to replace transformers with smaller ones, Wade said.

In 2008, with the help of a consultant, the [Leesburg, FL] utility put together a smart grid business plan that projected operational savings of $900,000 for the city’s electric system and an additional $400,000 for the water system, he said. Then, in 2009, Leesburg became one of 33 public power utilities to win smart grid grants from the Department of Energy under the American Recovery and Reinvestment Act. The utility received $9.75 million (which it must match) for its smart grid project, plus a $1.4 million energy efficiency and conservation block grant…With the grants, Leesburg is installing smart meters for all of its 23,000 customers, plus more than 4,000 energy management systems that will allow customers to program when they operate their electrical appliances such as air conditioners and water heaters. With the goal of reducing peak demand, the utility will look at a variety of incentive rate plans… Leesburg plans to give its customers a guarantee that those opting for an incentive rate will not pay more than the utility’s flat rate, he said. “The folks that want to participate, we want to reward,” he said.

Ponca City has 155 miles of fiber that connects eight towers, a wireless mesh system with 500 WiFi radios, and 28,000 electric and water meters, said Technology Services Director Craige Baird. That robust communications system provides a variety of benefits. After the utility replaced all of its meters, it found a lot of losses and recouped almost $500,000 in the first year in back sales, he said.

Portland, Maine, Borrows Money to Save Energy and Save Money

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/portland-maine-borrows-money-save-energy-and-save-money/

Unlike many cities, Portland, Maine, has forged ahead with a significant energy efficiency plan without federal stimulus dollars.  Simply borrowing money through bonding and investing in energy saving improvements, the city will – over 20 years – reduce operating costs by $700,000 per year and shrink its carbon footprint by 30 percent. Our favorite quote from the news story: "We are spending money to save money," Councilor John M. Anton told critics. "And we are borrowing at historically low interest rates. This is good fiscal management on the city’s part."  Bravo. Continue reading
