State Energy Self-Reliance Potential

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/state-energy-self-reliance-potential/

The following map was the headline graphic to our 2009 report, Energy Self-Reliant States, the report that inspired this blog.  I re-created the map for web viewing, so it’s now even easier to share how each state can meet its electricity consumption with in-state renewable energy resources. 

The renewable resources considered include on- and off-shore wind, rooftop solar PV, hydro, combined heat and power, and high-temperature geothermal.  Read the Energy Self-Reliant States report for more details.

Solar PV Pays for Itself on California Homes

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/solar-pv-pays-itself-california-homes/

For many improvements (e.g. kitchen, bath), you can capture a significant fraction of the value back when you sell your home.  For solar PV, you can get it all back:

This premium sales price was slightly higher than the installation cost, the study determined: “These average sales price premiums appear to be comparable to the investment that homeowners have made to install PV systems in California, which from 2001 through 2009 averaged approximately $5 per DC watt… homeowners with PV also benefit from electricity cost savings after PV system installation and prior to home sale.” [emphasis added]

As the article goes on to illustrate, the homeowner also receives the free electricity from the PV system. 

Go solar: it’s one heck of a money back guarantee!

Solar market moving toward distributed generation

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/solar-market-moving-toward-distributed-generation/

We think over the next three to five years the solar business will migrate heavily from a utility-sized solar business to a more of a distributed solar model driven by consumer demand not by government largesse.

Boulder Colorado Charts Course for Energy Self-Reliance

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/boulder-colorado-charts-course-energy-self-reliance/

When is it time to break up with your utility?  Perhaps it’s when they come to ratepayers for $30 million in cost overruns on a “free” smart grid project.  Or when they fail to meet deadlines to propose a new franchise agreement.  Or when they cite national security in an effort to avoid sharing load information.  Or when they crash your office with 9 employees to present their delayed franchise plan.  Or perhaps when the propose raising rates again to keep up with rising fossil fuel prices.

The citizens of Boulder, CO, have put up with a lot from Xcel Energy, the investor-owned utility that spans several states and currently provides the city’s mostly-coal-powered electricity.  So it was energizing to be invited to Boulder by Clean Energy Action last week to share how the city could move forward.  (my presentation below)

 

The city’s saga began in 2003, when it first began studying the option of municipalizing their electricity system, to have more control over the grid and increase clean energy production.  The city dropped the plan in 2007 when Xcel offered to build a free smart grid network, called SmartGridCity, a program that deployed advanced meters and fiber optic cables to improve information flow on the local electricity grid.  However, with a dubious cost-benefit ratio from the Xcel program and a desire for more clean energy, the city leaders are once again considering their options.

In 2010, the city of Boulder chose not to renew its franchise agreement with Xcel, essentially a monopoly charter that gives Xcel the exclusive right to serve Boulder’s customers for an annual fee.  The citizens of Boulder voted to tax themselves to replace those funds for five years, giving the city time to evaluate alternatives.  They’re taking it seriously.

For one, their current electricity costs keep going up, according to Anne Butterfield of the Boulder Daily Camera:

In Colorado, plunging costs for renewables are furled against the steady upward march of fossil fuels. In March, Xcel filed for an 18 percent increase in the “electric commodity adjustment” (the ECA on your bill) which allows fuel costs to get passed through to customers. This hike would increase a typical monthly bill by about $3 — with a resultant boost to the RESA of only six pennies. Every buck paid to fossils on Xcel’s system leads to two pennies sent to cost-saving renewables.

For another, they’ve already learned about options to dramatically increase the portion of electricity from renewables.  At a Clean Energy Slam, one company proposed providing 50% of Boulder’s energy from renewables by 2014, up to 80% by 2025.  Their planning process has also revealed new ways of thinking about the grid.  Freed from the paradigm of big, centralized baseload coal power plants, they’re looking at electricity from the “top down.”  They start with a load curve, throw in renewables and storage, and then see what gaps need filling, a process that prioritizes renewable energy instead of trying to shoehorn wind and solar into the gaps where fossil fuels fall short.

City officials aren’t just interested in clean, reliable electricity.  They also want to learn more about the potential for generating electricity locally.  While any new energy generator can add jobs and grow the economy, locally owned renewable energy creates job and economic multipliers. 

Local activists are also strongly committed to changing the status quo.  They’re not only looking for ways to green the local electric grid, but for ways for citizens and businesses to finance significant energy efficiency improvements as well as distributed renewable energy generation.

Boulder may end up joining the 2,000 existing municipal utilities in the United States and chart their own energy future or perhaps Xcel will finally bring them an attractive offer.  But by taking the issue into their own hands, Boulder will definitely do better than before.

Nevada Senate approves feed-in tariff

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/nevada-senate-approves-feed-tariff/

By a vote of 13 to 8, the Nevada Senate earlier this week approved a feed-in tariff to boost renewable energy develoment in the state.  The bill, SB184, now heads to the House where it is expected to pass.  Unfortunately, a gubernatorial veto is also expected, so supporters are hoping for a 2/3 majority in favor.

Really, Really Astonishingly Low Distributed Solar PV Prices from German Solar Policy

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/really-really-astonishingly-low-distributed-solar-pv-prices-german-solar-policy/

Last week I shared a graphic illustrating the dramatic fall in distributed solar PV prices in Germany, down to $4.11 per Watt installed, for rooftop systems under 100 kilowatts.  As it turns out, the graphic was out-of-date.  In Germany, the average installed cost for rooftop solar PV under 100 kW is $3.70 per Watt (update 7/13/11: $3.40 per Watt).  It’s a 50% drop in price since 2006, an average of 13% per year.

For comparison (as in the first post), here’s the average installed cost for under 10 kW rooftop solar PV in the United States, by state.

Chart is from page 19 of the brilliant report, Tracking the Sun III: The Installed Cost of Photovoltaics in the U.S. from 1998-2009 (large pdf).

Also from the previous post:

Did I also mention that the German policy (a feed-in tariff) driving solar costs down only costs German ratepayers the equivalent of a loaf of bread per month?  In the U.S., the federal renewable energy incentives cost $4 billion in 2007, or about $3.17 per household per month (or about the same price as an Italian baguette).

There’s only way to describe this German success: wunderbar!

FERC’s High Voltage Gravy Train

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/fercs-high-voltage-gravy-train/

Even as distributed generation shows economical and political advantages over centralized renewable energy, the Federal Energy Regulatory Commission (FERC) is running a high voltage gravy train in support of expanded transmission.  FERC’s lavish program is expanding large transmission infrastructure at the expense of ratepayers and more economical alternatives. Since 2007, FERC has had 45 requests… Continue reading

Astonishingly Low Distributed Solar PV Prices from German Solar Policy

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/astonishingly-low-distributed-solar-pv-prices-german-solar-policy/

Most renewable energy advocates are familiar with feed-in tariffs, also known as CLEAN Contracts.  They offer standard, long-term contracts for renewable electricity with prices sufficient to allow producers to get a reasonable return on investment (in Germany, it’s 6 to 8 percent). And research has shown that they tend to drive prices down more effectively… Continue reading

Oregon Town Gets a Lot of Solar for a Little Money

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/oregon-town-gets-lot-solar-little-money/

The upfront cost has always been the biggest barrier to solar PV adoption, and one Oregon town has found an innovative way to help its citizens buy down that cost.

The city borrowed from the sewer account to offer no-interest loans of $9,000 each. The repayment schedule, over four years, is tied to residents’ tax returns each spring, when they receive refunds of state and federal renewable energy tax credits.

All told, Lehman estimates the program will cost the city only $10,000 in lost interest over four years.

While the loan terms are short (4 years), the repayment plan is tied to the state and federal tax credit schedule, essentially allowing interested home and business owners the chance to finance solar directly with those credits, rather than having to put their own money up front.

The loan program spurred over 50 solar PV installations in 2010, in a town of just 16,500 residents.  The residents not only received discount financing, but the city helped aggregate the purchase of the solar panels to get participants a “group buy” discount.  Assuming a system size of 3 kilowatts and installed cost of $6.00 per Watt, the city’s $10,000 investment got their residents approximately $1 million worth of new solar power.

The increase in solar installation activity had an effect even for those who didn’t use the town’s financing option:

Ken Abbott, a retired postal employee, didn’t use the loan program but took advantage of the lower installation prices that resulted from the large number of buyers.

Pendelton’s lesson to cities is that you don’t need a lot of money to make it a lot easier to go solar.

Colorado Town Considers “How Much Renewable Energy is Feasible” – 80% by 2025?

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/colorado-town-considers-how-much-renewable-energy-feasible-80-2025/

A great story of a city looking to – literally – take ownership of its energy future:

The Colorado Renewable Energy Standard, as amended last year by the state Legislature, requires Xcel Energy to get 30 percent of its electricity from renewable sources by 2020.

 …Boulder leaders — who let the city’s 20-year franchise agreement with Xcel Energy lapse at the end of 2010 — are now considering whether they can get an energy mix for their residents with a larger percentage of renewable energy than what Xcel is offering.

…At the “Clean Energy Slam” event in February, which gave participants two minutes to pitch a vision for Boulder’s energy future, a representative of Southwest Generation told the crowd that he believed his company could provide Boulder with an energy mix of 50 percent renewables and 50 percent natural gas by 2014. And by 2025, the company could provide up to 80 percent renewable energy to the city, the representative, David Rhodes, said.

…Jonathan Koehn, the city’s regional sustainability coordinator, said adding more renewables is only part of the equation.

“We’ve heard a lot of concern that, perhaps, more clean energy is driving this analysis,” he said. “But this is about long-term economic stability. When we talk about what our portfolio might look like in the future, we don’t have a predetermined notion of a certain percentage of renewables. What we want is to be able to analyze how we can have long-term stable rates.”

It’s not just about clean energy and stable rates, however.  The decision to eschew a utility franchise was also about localization, described on a city website as “taking more control in determining:

  • Where the energy supply comes from – Locally produced
  • What types of energy are provided – Renewables over fossil fuels
  • How much we pay for it – Rate control

Local generation of renewable energy will add more to Boulder’s economy than importing clean electrons, and if those projects can also be locally owned (perhaps via a community solar project like the Clean Energy Collective is doing in Carbondale, CO) then the economic benefits multiply significantly.
