Should Solar Grid Parity Include Tax Credits?

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/should-solar-grid-parity-include-tax-credits/

In recent weeks, I wrote a Solar Grid Parity 101 and published an animated map of the year when major U.S. metro areas will reach solar grid parity.  The most frequent criticism was “you didn’t include tax incentives!” 

Yes, there is a 30% federal tax credit on the table until 2016 (barring Republican control of Congress and the White House) and it makes a substantial difference. Mouse over the following map to see the impact of the federal Investment Tax Credit on solar grid parity in 2016.

 

Solar Grid Parity

 

My one thought: if the ITC expires as scheduled, the 2017 map will have a lot more red than the 2016 one if we measure grid parity with incentives.

But you’ve seen the difference (from 3 states to 21 states with grid parity!), now vote in the comments:

Should the tax credit be included in a calculation of grid parity? Why or why not?

Note: This is a revision of the same post from last week, with an updated time-of-use pricing plan from Los Angeles. What if electricity cost more when the sun was shining? Many utilities are using new electronic “smart meters” to adjust the price of electricity as often as every 15 minutes, to reflect supply and… Continue reading

Solar Grid Parity 101

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/solar-grid-parity-101/

Solar grid parity is considered the tipping point for solar power, when installing solar power will cost less than buying electricity from the grid.  It’s also a tipping point in the electricity system, when millions of Americans can choose energy production and self-reliance over dependence on their electric utility. But this simple concept conceals a… Continue reading

Distributed generation needs less backup than centralized power generation

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/distributed-generation-needs-less-backup-centralized-power-generation/

 

One doesn’t need 540 MW of reserve to back up 540 MW of small-scale distributed generation, but one does need it to back up a single critical 540 MW unit.

The Challenge of Reconciling a Centralized v. Decentralized Electricity System

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/challenge-reconciling-centralized-v-decentralized-electricity-system/

As Americans transition their electricity system to the 21st century, they should ask this question.  Does it make sense to pursue strategies such as accelerating the development of new high-voltage power lines that reinforce an outdated paradigm of electricity delivery, or should scarce energy dollars be spent to add new clean, local energy to the… Continue reading

Utility Fights Dirty in City’s Battle for Clean Local Energy

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/utility-fights-dirty-citys-battle-clean-local-energy/

Banner from Boulder's Clean Local Power campaignIn just three weeks, citizens of Boulder, CO, will vote on whether to begin a big, formal process to unplug from Xcel Energy’s system and plug into local energy self-reliance.  The vote to form a municipal electric utility could set a precedent for communities across the United States to keep millions of dollars local instead of sending them to remote electric utilities each year. 

The vote on ballot measures 2B and 2C is the culmination of a multi-year struggle by the city of Boulder meet the Kyoto greenhouse gas emission targets by getting less coal power and more renewable energy from its investor-owned utility. 

At every turn, the utility has stalled local efforts.  

When the city first considered municipalization, Xcel offered to finance and build a local smart grid but has since been allowed by the state’s public utility commission to charge Coloradans for significant cost overruns.  When the city asked Xcel to bring in more clean energy, the utility offered to build a new wind plant and import its power from across the state only if Boulder citizens agreed to pay more when the wind blew and pay when it didn’t, too.  Despite the ill nature of the offer, the city offered to put it on the ballot along with a vote to municipalize, but Xcel refused, demanding that the city also offer citizens a separate “status quo” measure.

In contrast, a Boulder-owned utility offers enormous clean energy and economic opportunity without having to beg a big, private company.  The city could increase renewable energy production by 40% from multiple, local sources without increasing rates, according to a citizen-led peer reviewed study.  The economic value of local energy ownership would multiply within the city’s economy to as much as $350 million a year, according to research by the National Renewable Energy Laboratory.  

But with $100 million a year in revenues from Boulder ratepayers on the line, Xcel’s fight is getting as dirty as its nearby Cherokee coal plant.  Xcel has dumped over $450,000 into a vote no campaign, 10 times the expenditures of the grassroots groups supporting the municipalization ballot measure.  The utility’s front group has flogged a web advertisement that falsely asserts that electricity will be unreliable if the city has control, even though 1 in 7 Americans gets their (reliable) electricity from municipal utilities.   Xcel has posted job notices on light poles offering residents up to $12 an hour to work as “grassroots” utility flaks.  And in a purely spiteful move, Xcel also succeeded in banning Boulder resident Leslie Glustrom from participating at the Public Utilities Commission, where she had asked tough questions about Xcel’s new coal power plants and proposed rate increases.

Locals are fighting back.  Citizens for Boulder’s Clean Energy Future has organized a crack team of technical and financial experts to model the impact of the municipal utility and is pounding the pavement to counter Xcel’s campaign of misinformation.  The coalition has received endorsements from dozens of local elected officials and businesses, two local newspapers, and nearly one thousand residents.   Even President Obama’s former green jobs advisor Van Jones starred in a video endorsing Boulder’s effort for local energy self-reliance.

The battle for local control isn’t just in Boulder.  Recently a number of Massachusetts towns have pursued municipal electric plants when the private electric company took too long to restore power after Hurricane Irene.  And in nearby Longmont, CO, citizens may vote to use their existing fiber optic network to provide better internet broadband services (if citizens can overcome the $250,000 being spent by private providers CenturyLink and Comcast).

The stakes are high.  Buying electricity from Xcel sends $100 million out of the Boulder economy each year, and helps perpetuate a centrally-controlled grid reliant on coal-fired power (and often hostile to wind power).  Ratepayers across America may not have the chance to weigh in on Boulder’s vote this November, but they should watch intently (and donate if they like), because Boulder citizens may be firing the first “shot heard round the world” for local control of their clean energy future.

California Governor to Western Grid: No Imports of Renewable Energy Needed

The content that follows was originally published on the Institute for Local Self-Reliance website at http://www.ilsr.org/california-governor-western-grid-no-imports-renewable-energy-needed/

Western grid operators have been making plans for large-scale renewable energy imports into the California electricity market, prompting the governor’s Senior Advisor for Renewable Energy Facilities to write a “self-reliance” response.

Here are a few highlights of his letter to the Western Electricity Coordinating Council (WECC):

California has plenty of in-state development: “The California Independent System Operator indicates that renewable projects totaling 70,000 MW of installed capacity [nearly enough to meet all of the state's peak summer demand] are seeking to connect to the CAISO-managed grid.”

Transmission costs are up, waaay up.  In particular, “the developer of at least one significant line, TransWest Express, expects the project to cost about 70 percent more than WECC’s original assumptions…we thus appreciate the ongoing efforts of WECC staff to review these and other assumptions and to revise capital cost assumptions upward.”

Transmission line risks: “transmission lines proposed to stretch hundreds of miles over private and public lands face significant permitting and development risk – perhaps most so in the case of DC lines, which offer few electrical benefits to the states they cross.”

In summary, California has a robust in-state market for renewable energy and sufficient in-state renewable resources to serve its entire electricity needs, so Western states would do well to temper their export optimism.
