Distributed Solar: Cleaner and Smarter than Oil

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/distributed-solar-cleaner-and-smarter-oil/

A delightful infographic from 1BOG, residential solar aggregators who are driving down the cost of solar PV across America. 

They also note that the cleanup cost for the oil spill – $32 billion – would buy enough solar to power all of Los Angeles county for 30 years, for less than 15 percent of what Los Angeleos are expected to pay through 2040.

Cash Incentives for Renewables Cost Half as Much as Tax Credits

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/cash-incentives-renewables-cost-half-much-tax-credits/

Using the tax code to support wind and solar power significantly increases their cost.  I wrote about this problem last year because project developers were selling their federal tax credits to third parties at 50 to 70 cents on the dollar.

Along these lines, the Bipartisan Policy Center released a study [last week] showing that simply handing cash to clean energy developers is twice — yes, twice — as effective as supporting them through tax credits. [emphasis added]

The problem is that all but the largest renewable energy developers or buyers can’t capture the full value of the federal tax credits.  So, prior to the economic collapse, a number of enterprising investment banks (and others) started buying up tax credits to reduce their tax bills. 

This was great for big banks, but lousy for taxpayers and electric ratepayers.  In fact, using tax credits instead of cash grants for wind and solar projects increased the cost per kilowatt-hour produced by 18 and 27 percent, respectively.  (Wait, why not 50 percent?  Because even though the tax credit is only half as good as cash, the cash payment only covers up to 30 percent of a wind or solar project’s costs.  So cash in lieu of tax credits can only improve that portion of a project’s finances.)

Seen another way, if the $4 billion spent on renewable tax incentives in 2007 had been given as cash instead, it could have leveraged 3,400 MW of additional wind power and 52 MW of additional solar power.  This would have increased incremental installed wind capacity in 2007 by 64%, and installed solar capacity by 25%. 

The increased costs come from higher prices that utilities pay for wind and solar power (and pass on to consumers) as well as the the cost to taxpayers of passing half of the tax credit value to investment bank shareholders instead of wind and solar projects.

The problem isn’t solved, but has simply been postponed.

When the economy tanked, so did profits (and tax liability) for big banks.  Wind and solar producers had no one to buy their tax credits and the entire industry was in danger of collapsing.  The adjacent chart illustrates the idiocy of relying on the tax code for energy policy.

Congress stepped in with a temporary fix, allowing project developers to receive a cash grant in lieu of the tax credit.  The temporary cash grant (currently extended through 2011) kept the wind and solar industry running during the recession and has saved taxpayers and ratepayers billions of dollars. 

It’s also helped level the playing field, allowing for local ownership of wind and solar projects, rather than requiring complex tax equity partnerships.  It’s meant more revenue from wind and solar staying in the local community.  And this means a larger, stronger constituency for renewable energy.

The cash grant option will expire at the end of 2011, but hopefully the climate hawks and fiscal hawks in Congress will take note: we can support wind and solar at half the price with smarter policy.

Grid on Hawaiian Island of Oahu Can Handle 25% Wind and Solar

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/grid-hawaiian-island-oahu-can-handle-25-wind-and-solar/

A new study released in February adds evidence that utility grids can handle high levels of renewable energy penetration.  The latest study examined adding 500 MW of wind to the electric grid on the Hawaiian island of Oahu (home to Honolulu).  The result would be a grid with 25% of the energy coming from wind and solar power.

Results of this study suggest that 400 MW of off-island wind energy and 100 MW of on-island wind energy can be integrated into the Oahu electrical system while maintaining system reliability. Integrating this wind energy, along with 100 MW of solar PV, will eliminate the need to burn approximately 2.8 million barrels of low sulfur fuel oil and 132,000 tons of coal each year. The combined supply from the wind and solar PV plants will comprise just over 25% of Oahu’s projected electricity demand. [emphasis added]

By its nature, the wind and solar power will be largely distributed generation, although much of the wind power reaching Oahu would arrive via undersea transmission.  Regardless, it’s a promising opportunity for Hawaiian energy self-reliance.

Colorado Solar Permitting Fees May Fall With New Legislation

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/colorado-solar-permitting-fees-may-fall-new-legislation/

A few weeks ago we posted on the adverse impact of solar permitting fees on residential and other small-scale distributed solar PV projects.  Vote solar provides an update and progress in Colorado:

Vote Solar recently teamed up with COSEIA to collect and evaluate the current state of [solar] permitting in 34 local jurisdictions throughout the state.  Survey says? In practice, solar permitting requirements vary widely from one jurisdiction to the next due to different permitting plan review processes and other extraneous fees. This has resulted in piecemeal local permitting practices that are often costly, complex, non-transparent and time-intensive. The process is arduous for solar installers and increases costs to consumers. Among the 34 cities and counties surveyed, Breckenridge, Colorado Springs, and Denver are doing permits on the fast and cheap. On the slower, more expensive end are Arapahoe County, Aurora and Commerce City…

The findings reinforce the need for Colorado’s juridications to adopt standardized, streamlined solar permitting practices. The Colorado Fair Permit Act (HB 11-1199) has passed out of the House on a 64-1 vote and now moves on to the Senate. Stay tuned!

Solar permitting remains a looming cost barrier to distributed solar, so it’s great to see that Vote Solar’s Project:Permit is gaining traction.

UK Solar Incentive Cuts May Also Distribute Solar Rewards More Widely

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/uk-solar-incentive-cuts-may-also-distribute-solar-rewards-more-widely/

A proposed revision to the United Kingdom’s feed-in tariff program may have created an uproar, but it may also help spread the economic benefits of solar more widely. 

The proposed changes, announced last week, would reduce solar payments for large solar projects (50 kilowatts and larger) by 50 percent or more, but leave payments for smaller projects largely intact.  The following tables illustrate:

Old Tariffs Price paid per kilowatt-hour
GBP USD Size
£0.41 $0.66 < 4kW retrofit
£0.36 $0.58 4 to 10 kW or <4 kW new build
£0.31 $0.51 10 to 100 kW
£0.29 $0.47 100 kW to 5 MW
 
New Tariffs Price paid per kilowatt-hour
GBP USD Size
£0.41 $0.66 < 4kW retrofit
£0.36 $0.58 4 to 10 kW or <4 kW new build
£0.31 $0.51 10 to 50 kW?
£0.19 $0.31 50 to 150 kW
£0.15 $0.24 150 to 250 kW
£0.09 $0.14 250 kW to 5 MW

The new tariffs will help redistribute more of the feed-in tariff (FIT) program revenue to smaller projects.  The most likely manner is simply by giving less money per kilowatt-hour (kWh) to the large projects, leaving more for the small projects.  The following charts will illustrate. 

Let’s assume that under the old FIT scheme, each project size tranche provided 25% of the solar PV projects under the program (see pie chart).

However, since a 2 MW project produces many more kWh than a 3 kW project, the revenues will skew heavily toward the larger projects.  For the sake of simplicity, I assumed that the midpoint of each size tranche was a representative project and that they all produced the same kWh per kilowatt of capacity. 

The revenue distribution can be seen in the second pie chart:

Essentially, all the FIT Program revenue was going to the largest projects.  Even if three-quarters of projects were under 4 kW, they would still only represent 3 percent of program revenue, with 93 percent accruing to the projects over 100 kW.

Under the new FIT scheme, the prices paid to larger solar PV projects are sharply reduced. With projects evenly distributed between the now six size tranches, much less of the program revenue goes to large projects.

The projects under 100 kW have roughly tripled their share, from 3 percent to 10 percent of revenues. 

Of course, the lower prices for large solar projects could have another impact: killing large solar projects completely.  Let’s assume that the new prices for projects over 50 kW (that experienced the steepest revenue decline) are simply too low and that all development ceases. 

The first pie chart shows the project allocation in the FIT program without any projects over 50 kW.  As described, we have an even distribution (# of projects) between the smallest three size categories, and no projects 50 kW or above.

The next chart shows the revenue allocation of the FIT program under this assumption.  Now, nearly 30 percent of program revenue accrues to projects 10 kW and smaller. 

If we assume that instead of an even allocation of projects, we have an even allocation of capacity between the size tranches (e.g. 30 MW, 30 MW, 30 MW), then the revenues would be split evenly between the remaining size categories and two-thirds of the solar FIT program would be flowing to solar projects 10 kW and smaller.

While it’s unlikely that the government plans to eliminate the large solar PV market with its price revisions, the overall effect is likely to be a transfer of program revenues to smaller projects.  The advantage in this strategy is that these revenues will be spread over a much larger number of projects and project owners, creating a larger constituency for supporting solar power and solar power policies.

Utilities in Ohio Claim They Can’t Meet State’s Solar Standard

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/utilities-ohio-claim-they-cant-meet-states-solar-standard/

Vote Solar reports that Ohio utility First Energy is claiming for the second straight year that it can’t meet the state’s solar carve out. 

First Energy Corp – which is parent company to Toledo Edison, Ohio Edison and Cleveland Electric Illuminating - reports that they were unable to find enough solar renewable energy credits in Ohio needed to satisfy their 2010 benchmark for solar energy. First Energy has filed for  force majeure for the second year in a row claiming that it was a circumstance beyond their control, a legal ‘act of God’,  that prevented the company from buying the needed SRECs….it’s awfully suspect that an Act of God would occur twice in a row.

It is, for two reasons. First, as we detailed in our 2009 report – Energy Self-Reliant States – Ohio is like many states in having sufficient rooftop space for solar PV to supply 20 percent of the state’s electricity.  There’s no shortage of sunshine.

Additionally, it’s far less expensive for the utility to buy solar than to pay the alternative compliance payment.  In 2011, utilities must either acquire the necessary solar renewable energy credits (RECs) or pay $400 per megawatt-hour (MWh) that they fail to acquire. 

However, a large-scale solar PV system in Ohio with an installed cost of $6 per Watt only needs 22.6 cents per kWh ($226 per MWh) to break even over 25 years (if they use federal incentives).  With a long-term contract with a known price for solar RECs (something they have yet to offer), First Energy can surely find a solar developer willing to help them out.

After all, that’s exactly what other Ohio utilities are doing:

First Energy could have followed the example of AEP Ohio, a neighboring utility that has successfully entered into a long term PPA with a 10 MW solar farm and is in development for another 49 MW solar facility as we write. If AEP can do it, so can First Energy.

First Energy’s problems with solar have little to do with God or their state’s solar resources, and everything to do with giving up.

How Community Ownership Can Save Wind Power

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/how-community-ownership-can-save-wind-power-2/

Community ownership may provide the solution for increasing resistance to wind power in the United States. 

Wind power has expanded rapidly in recent years, but the new wind farms have a common characteristic: absentee ownership.  These large wind farms promise a broad expansion of clean energy production, but not a commensurate expansion in local economic benefits.  True, every wind power project will create some jobs and ripple effects in the local economy, but with absentee ownership most project benefits will leave the community (whereas locally owned projects have significantly higher rewards).

Without a say or stake in the turbines remaking their local skyline, communities have raised red flags.  The result is more restrictive wind siting policies and opposition to new high-voltage transmission lines that may carry wind power from remote areas to major cities. 

The wind industry’s initial reaction to local resistance seems to attempt an end-around, looking for states to pre-empt local siting authority and the federal government to pre-empt state transmission planning authority.  Unsurprisingly, such moves win few friends for wind power.

There’s an alternative.

Some wind developers have learned that gaining local acceptance means rewarding not just the landowners who host project turbines, but neighbors who will also be affected by the turbines’ proximity.  In the United Kingdom, state policy is requiring wind farms to pay into community funds (perhaps inappropriately, as a tool to offset severe budget cuts).  But this policy has two drawbacks.  For one, it only buys off the opposition, it doesn’t transform them into wind advocates.  Second, it fails to take advantage of a community’s capital and the interest of residents in owning a stake in local wind power, rather than simply observing.

Community wind projects typically find a warmer welcome:

“In local communities, there’s been little to no opposition to wind projects,” said Eric Lantz, a wind policy analyst at the Renewable Energy Laboratory and a co-author of the study. “There’s more pride taken when you’re able to participate with an ownership stake.”

Several studies reinforce the idea that a local ownership stake is key to acceptance of wind projects.

Community ownership not only eliminates most local opposition, but makes locals into stakeholders in the success of wind power.  A new 25 megawatt wind project in southwestern Minnesota will feature significant community ownership.  Just listen to the heartfelt pride in wind power from these members of a wind power cooperative in the United Kingdom:

Community wind projects are also more likely to reduce demand for long-distance transmission, because gaining local acceptance means wind farms can be built closer to cities and because communities lack the capital to build that largest-scale wind farms.  This is a key issue, since there’s yet to be a community-owned transmission line.

While community wind could save the wind industry, it won’t be without some better rules.  Community wind projects still require financial acrobatics, largely because the federal incentive for wind power (the Production Tax Credit) can only effectively be used by big banks and investment firms.  And utilities tend to favor a few negotiations with large wind projects rather than many negotiations with smaller projects to meet their renewable energy obligations.  Laws like Minnesota’s Community-Based Energy Development statute or CLEAN contracts can pave the way for more community-based wind projects.
 
Wind power is a key element of transforming our electricity system to clean energy and to combatting climate change.  But it’s future may hinge on the willingness of the wind industry to embrace community ownership.

Nuclear – too costly to build

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/nuclear-too-costly-build/

It’s telling that the insurance industry won’t touch nuclear projects unless governments cap their liability. In Canada, the cap is now $650 million on disasters that can cost many billions of dollars to battle, excluding long-term economic impacts. Taxpayers, of course, cover the rest. Without such caps, the industry argues the cost of insurance would simply be too high.

Community Funds for Wind Power

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

Public officials are looking for ways to reduce opposition to wind farms and the United Kingdom is piloting a “community wind fund” program for all new wind projects.  Under the program, each wind project must pay in £1000 per megawatt (~$1600 per MW), per year, for 25 years into a community fund where the project is located.  The funds would help maintain public support for wind power, but also (conveniently for the conservative government) replace reduced government funding for basic services:

“With all the current talk of libraries, community centres and sports halls being closed because of government cuts , here’s a great way for local communities to replace that funding. Local wind projects will from now on not just bring the benefits of local green electricity, but also the funding of vital social projects that government cuts would otherwise shut down.”

The impact for the community is significant.  Compared to the typical land leases (often $5,000 per turbine for the host landowner), the community fund payments would increase local revenue by over 60 percent, with the additional funds spread to the entire community rather than just the lucky turbine hosts.

The impact on turbine owner net revenue is small but not negligible, reducing the net present value of the project by about 3 percent. 

Using community funds to overcome local opposition may be worth the revenue reduction for the wind project owner, but the U.K. government strategy of using wind parks to offset (some) budget cuts represents a strategy that is unlikely to work well in the United States.

Cost, Not Japan Crisis, Should Scrub Nuclear Power

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/cost-not-japan-crisis-should-scrub-nuclear-power-2/
please ignore this image
explosion at Japanese nuclear reactor

The plumes of smoke rising from Japan’s Fukushima Daiichi nuclear reactor create a visceral reaction.  But the crisis should not persuade Americans to abandon nuclear power. 

Instead, Americans should abandon nuclear power for its prohibitive and un-competitive costs.

The wildly escalting costs of nuclear plants under construction in the U.S. are a perfect example.  A pair of proposed nuclear power plants in Florida have “overnight” costs of $3,800 per kilowatt, but since nuclear power plants actually take eight years to construct, the total estimated project costs are closer to $6,800 per kilowatt (kW) of capacity.  This figure is reinforced by an estimate for Progress Energy’s two new units ($6,300 per kW $8,800 per kW), and Georgia Power’s new plants ($4,000 per kW $6,335 per kW), both still incomplete. 

As Mark Cooper notes in his thorough analysis of the so-called nuclear renaissance, this is nothing new.  Most nuclear projects haven’t come in on budget, or even close.

But let’s be generous for a moment and assume the U.S. utilities can hold to their current cost estimates.  What do those costs mean to consumers?  At $6,500 per kW, the expected cost of nuclear electricity is over 15 cents per kWh ($150 per MWh).

At that price, investment bank Lazard estimates that only two technologies are more expensive than nuclear (crystalline silicon solar PV and natural gas peaking plants).  But solar PV has significant near-term cost reduction potential and “gas peaking” only refers to the way we use natural gas, not its inherent cost (see Gas Combined Cycle).  In the time it would take to build a nuclear plant (6-8 years, optimistically), every commercial energy technology could produce electricity for less.

Subsidies can change the picture – the picture most Americans have of nuclear, that is.  The Union of Concerned Scientists recently reported that nuclear subsidies total nearly 7 cents per kWh, twice what a typical wind power plant receives and similar to the federal incentives offered for solar power.  It’s time to let the market pick our winners, not outrageous government subsidies for nuclear power.

Beyond its (escalating) costs and huge subsidies, nuclear power also reinforces a centralized grid paradigm where the financial winners are utilities who pass through cost increases onto the backs of ratepayers (sometimes before the plant begins operations).  Did we mention that Florida Progress will require $3 billion in transmission upgrades to accommodate its new nuclear plants?  Compare that to distributed renewable energy sources that can often interconnect to the grid with a minimum of infrastructure upgrades.

The crisis in Japan is terrible, but we shouldn’t eschew nuclear power for its ability to cause immensely disproportionate harm during natural disasters.  Instead, we should abandon this costly boondoggle for more cost-effective and renewable energy sources.
