Electricity Deregulation Burns Ratepayers, Again

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/electricity-deregulation-burns-ratepayers-again/

A new report about electric grid deregulation in Texas shows (yet again) that deregulation of electricity leads to much higher ratepayer costs:

In 2009, the report found 93 percent of Texans served by deregulated electric companies were charged above the national average. By comparison, 81 percent of customers outside deregulation paid less.

A 2007 story in USA Today examined state electricity deregulation policies and also found that they hadn’t ended well for ratepayers:

While average prices rose 21% in regulated states from 2002 to 2006, they leapt 36% in deregulated states where rate caps expired, according to a study by Ken Rose, senior fellow at the Institute of Public Utilities at Michigan State University.

Texas apparently didn’t learn the lesson from its hometown team and deregulation poster boy – Enron – which manipulated California’s deregulated market to precipitate the 2000-01 California electricity crisis.

Southern California Edison Buys 250 MW of Distributed Solar PV for Less Than Electricity from Natural Gas

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/southern-california-edison-buys-250-mw-distributed-solar-pv-less-electricity-natural-gas/

Updated 3 PM: Preliminary numbers had suggested that Southern California Edison’s distributed rooftop solar PV purchase would be among the most cost-effective solar projects in the world, and data released yesterday confirmed that:

Southern California Edison has selected 250 MW worth of solar bids from companies able to produce solar electricity for 20 years for less money annually than the 20 year levelized cost of energy of a combined-cycle natural gas turbine power plant.

SCE’s bidding process for smaller renewable projects is smart. These small projects do not face the multi-year bureaucratic delays for extensive reviews, like most utility-scale solar, so each small unit can be built as quickly as normal commercial rooftop solar projects. They are made up of multiple distributed solar installations of under 20 MW, which in combination total a power plant-sized 250 MW.

…The requirement is that the renewable energy has to be priced to cost no more than the Market Price Referent (MPR) – which is an annual calculation of the 20 year levelized cost of energy of a combined cycle gas turbine.

The MPR has recently been around 11 cents per kilowatt-hour, so the solar PV projects will produce electricity for less than the retail rate in southern California.  There’s indication of enormous distributed PV demand, because SCE received bids for up to 2,500 MW of projects, but only accepted 250 MW.

In-State Renewable Energy Development and the Commerce Clause

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/state-renewable-energy-development-and-commerce-clause/

Can a state with a renewable energy mandate require green jobs to stay at home?  Litigation has made states into tepid defenders of their job rights, but states have the legal ground to go great lengths to keep more of the economic development from their renewable energy industry inside their borders.

No renewable energy mandate passed a state legislature without the promise of thousands of new jobs, but many states have shared the recent experience of Massachusetts: the state’s largest solar manufacturing plant announced that it is moving production to China.  Evergreen Solar is moving despite the state’s commitment of $44 million in subsidies to support the plant and its manufacturing jobs.  The state is losing out on manufacturing jobs despite its citizens’ commitment to (if necessary) pay more for electricity from renewable sources.

In contrast, last week I wrote about Ontario’s clean energy program, well on its way to 5,000 megawatts of new renewable energy production and supporting over 40,000 new jobs.  Over 20 new manufacturing plants have been announced.  The keystone of this program is a ‘buy local’ rule that requires wind and solar power projects who want the province’s attractive power payments to be constructed with at least 60 percent of their materials ‘made in Ontario.’  Ontarians are getting cleaner electricity and significant economic development for their clean energy commitment.

U.S. states can do much more to secure the economic benefits of their clean energy mandates, even if they can’t copy Ontario’s law verbatim (see our recent report on Ontario’s program for more on the international trade controversy).

Traditionally, U.S. states have limited their economic development policy to subsidy programs, offering grants, loans, and tax breaks to manufacturers to locate within the state.  Businesses let states bid against one another for scarce jobs.  The result is a repeat of Massachusetts’ experience with Evergreen Solar.  Manufacturers accept subsidies and then leave when it suits their bottom line.

Some states have tried more.  Ohio and Illinois require part of their renewable energy standard to be meet with in-state projects.  Other states provide greater credit toward compliance with their renewable energy standard for in-state projects.  One state, Washington, offers multipliers to a state tax credit for projects with “made in Washington” parts. 

Massachusetts tried to require its utilities to sign long-term contracts with in-state renewable energy suppliers, but the state backed down in the face of a lawsuit from renewable energy supplier TransCanada.

No state has gone as far as Ontario to require local purchasing of components, partly because more robust policies to require in-state development have often been threatened with lawsuits under the Supreme Court’s Dormant Commerce Clause. 

The linchpin to a commerce clause dispute is whether the law in question discriminates against out-of-state economic interests and, in particular, whether it burdens them while benefitting in-state interests.  Enacted in a U.S. state, Ontario’s buy local requirement would likely trigger than discrimination clause, requiring the state to prove that the law “advances a legitimate local purpose that cannot be adequately served by reasonable nondiscriminatory alternatives.” (Source: Richard Lehfeldt, Woody N. Peterson, and David T. Schur.  Commerce Clause Conflict.  (Public Utilities Fortnightly, December 2010)).   Success in this situation is rare, and yet clean energy economic development may meet the requirements.  A recent article in Public Utilities Fortnightly magazine on the Massachusetts case highlights how states could move beyond jobs subsidies:

First, be explicit about the incentives being offered for in-state investment.  In particular, “The opportunity to enter into a long-term PPA should be one of the benefits offered to successful bidders as part of the state’s development initiative, not the starting point.”  In fact, the article notes, this is exactly what happens in regulated electricity markets, where the state provides a utility franchise and the exclusive right to build and rate-base new power generation.  The PPA follows from the commitment to local development.

The state must also be explicit about the functional difference between a power plant developed in-state as opposed to out-of-state, with specifics about the technology and the site.  For example, redeveloping a brownfield site in state is much more valuable than simply importing clean electricity. 

Finally, states have legitimate environmental objectives for in-state power generation.  “A state that seeks new in-state renewable power plants may increase its reserve margins, improve its air quality, displace fossil-fuel based generation, avoid transmission congestion charges that may apply, and may also avoid or defer the need to build new transmission lines.”  All of these are “legitimate local purpose[s] that cannot be adequately served by reasonable nondiscriminatory alternatives.”

In other words, under the strict discrimination clause there is room for states to favor local development.  But there are also several nondiscriminatory strategies that can also pass legal muster.

States that favor in-state production without placing an “excessive burden” on out-of state entities have nondiscriminatory policies.  There are several illustrations of this at work.  In Minnesota, an ethanol producer incentive provided 15 cents per gallon of ethanol produced in-state and nothing for out-of-state suppliers, who were still allowed to sell in Minnesota.  The state of Washington provides a significant multiplier to its solar PV incentives for domestically produced inverters and solar modules. 

If U.S. states fear the legal conflict over a discriminatory clean energy policy, they could instead emulate Turkey.  Turkey provides renewable energy producers a standard offer, long-term CLEAN contract for anyone who builds in the country, but they provide bonus payments for renewable energy projects that are “made in Turkey.”  These payments increase the per kWh contract anywhere from 32% to 146%, depending on the renewable technology. 

Over thirty states have committed themselves to renewable energy and potentially higher electricity costs.    In exchange, states should consider their legal authority to keep those jobs within state borders and to the economic advantage of its citizens.

FERC Affirms that CLEAN Contracts (Feed-in Tariffs) are Legal

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/ferc-affirms-clean-contracts-feed-tariffs-are-legal/

Overruling a utility challenge, the Federal Energy Regulatory Commission (FERC) affirmed today that states have the right to set prices for mandated renewable energy purchases and that these prices may vary by technology:

“[W]here a state requires a utility to procure energy from generators with certain characteristics,” the state may set the wholesale rate (known as ‘avoided cost’) for that specific type of energy.  Id. at para. 30. Therefore, a state can require utilities to purchase electricity generated from differentiated technologies (wind, solar, wave, etc.) and set the rate for purchases from each of these generators.

EV Charging Station Charges Cars and Supports the Grid

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/ev-charging-station-charges-cars-and-supports-grid/

The batteries and the solar cells themselves are something like shock absorbers for the grid. If drivers want to charge up their cars during peak periods on the grid, the charging station’s batteries will meet part of that demand so that the impact on the grid is milder. Likewise, the solar cells will chip in with some energy, lessening the load on the grid.

“If with new technologies we can control these resources on the distribution side, we can eliminate the need for potentially very expensive upgrades to the distribution system,” said James A. Ellis, the senior manager for transportation and infrastructure at the T.V.A.’s Technology Innovation Organization.

A Look at Electric Vehicle Economics

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/look-electric-vehicle-economics/

The blog Camino Energy has a very detailed analysis of the payback on an electric vehicle (Nissan Leaf) compared to a conventional Toyota Camry.  The author looks specifically at Northern California, where off-peak electricity prices are low enough that utilities could offer electric vehicle (EV) charging at 5 cents per kilowatt-hour (kWh).  At that rate, with solely night-time charging of the EV and driving 12,000 miles a year, a Nissan Leaf pays back in 5 years. 

The author provides a sensitivity analysis against higher electricity prices, and his entire post is worth reading.

Nova Scotia Proposes Feed-in Tariffs Solely for Community-Owned Projects

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/nova-scotia-proposes-feed-tariffs-solely-community-owned-projects/

Joining Ontario and several U.S. states, the Canadian province of Nova Scotia has proposed a new twist on a common clean energy program. The policy provides a guaranteed, long-term contract for wind, biomass, hydro, and tidal power producers and offers them the same return on equity provided to utiltiies. Continue reading

Home Solar Cheaper Than Every Concentrating Solar Power Plant

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/home-solar-cheaper-every-concentrating-solar-power-plant/

A residential rooftop solar PV system in Los Angeles, CA, has a cheaper cost per kilowatt-hour of electricity delivered than the most cost effective, utility-scale concentrating solar power plant. 

In 2010, a buying group called Open Neighborhoods openly advertised an opportunity to get a solar PV system installed for $4.78 per Watt (not including any tax credits, rebates, or grants), a system that would produce approximately 1,492 kilowatt-hours (kWh) per year (AC) for each kilowatt of capacity (DC). 

Based on the best available public information about the costs and performance of operational concentrating solar thermal power plants, the PS10 solar power tower – an 11 MW installation in Spain – has the lowest levelized cost of operation of any concentrating solar power plant that produces electricity.  PS10 had an installed cost of $4.15 per Watt and produces 2,127 kWh per kW of capacity. 

However, due to higher operations costs and a higher cost of capital (8% rather than 5%) for a concentrating solar power plant, the levelized cost of the residential rooftop system (17.3 cents per kWh) is less than that of the power tower (19.9 cents per kWh).

This analysis also does not include any transmission infrastructure or efficiency losses, either of which would increase the levelized cost of the concentrating solar power plant.  It also did not include the lower price point from Open Neighborhoods, which advertised a possibility of driving the price down to $4.22 per Watt (driving the levelized cost down to 15.3 cents per kWh).

The Southern California Edison project, also featured in the chart, is another example of low-cost distributed solar PV, with the 250 MW project spread across commercial rooftops in 1-2 MW increments but still achieving large scale. 

Ultimately, this data further confirms that distributed solar can be delivered less expensively than centralized solar power.

California Launches Compromise Small-Scale Renewable Auction

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/california-launches-compromise-small-scale-renewable-auction/

The California Public Utility Commission officially launched its Renewable Auction Mechanism (RAM)* last week, to spur more development in renewable energy projects smaller than 20 megawatts. 

The good and bad news is summarized quite well by the FIT Coalition, with the good news being:

  1. A strong focus on the < 20 MW market segment, also known as Wholesale Distributed Generation if the project connects to the distribution grid.
  2. Recognizes value of “locational benefits,” rewarding projects that site close to load to avoid unnecessary transmission expenditures – “(massive capital expenditures, decade-long build-outs, and significant line and congestion loses)”
  3. Requires utilities to provide specific grid details to help developers select project sites before they commit.

Points 1 and 2 highlight an increasingly recognized issue: meeting the near-term benchmarks in state renewable energy standards may be impossible if states rely on centralized, transmission-dependent projects.  Sub-20-megawatt projects can quickly sum to large quantities of renewable energy, capture most economies of scale, and come online much faster that large, centralized projects.

Point 3 is huge, as well, because it finally addresses a market failure where distributed energy project developers could not get information about grid “sweet spots” for plugging in smaller scale renewable energy without significant infrastructure upgrades.  It’s an issue too rarely discussed, with a rare exception being our 2008 report on Minnesota’s potential to meet its state RPS without significant new high-voltage transmission lines (backed by two state-sponsored studies).

The bad news is that the CPUC missed several opportunities to maximize the potential for distributed generation:

  1. It allows participation by transmission-connected projects, which will not carry the same advantages as distribution-connected projects – “producing energy close to load and avoiding the significant costs, timeframes, and environmental issues associated with transmission.”
  2. It institutes a lop-sided playing field that will favor well-established companies and larger projects.
  3. It perpetuates the high failure rate of solicitation programs: “In general, California’s solicitation-based RPS programs result in more than 95% of the bid capacity to be rejected by the utilities or to be abandoned by developers in the end due to underbidding.”  These rejections lead to enormous stranded development costs, as much as $100 million in one solicitation.

Despite the bad news, it’s a promising “pilot” program that will support 1 gigawatt of distributed renewable energy.   Let’s hope it improves with time.

*And folks suggest feed-in tariff is a lousy policy name…Speaking of which, a number of media stories indicate that this is California’s take on a “feed-in tariff.”  That’s like saying like soccer is Europe’s take on American football.  One is an auction, the other is a standard contract with prices based on the cost of generation.
