Smart Grid City-PUC Decision Withholds $16 Million from Xcel

Submitted by Leslie Glustrom

On February 8, 2011, the Colorado Public Utilities Commission published Decision C11-0139 withholding $16 million from Xcel until the utility is able to demonstrate a “coherent and valuable future” for the Smart Grid City (“SCG”) project in Boulder, Colorado.

Decision C11-0139 is attached below.

In particular, the PUC asked Xcel to demonstrate:

  • A strategic plan for the use of the Smart Grid City investment
  • A credible promise of consumer and utility benefits sufficient to justify the cost overruns
  • The ability of customers to make practical use of the Smart Grid City on their side of the meter through in-home devices.
  • (See paragraph 19, page 6 Decision C11-0139, Colorado PUC)

The Commission summarized its position on the Smart Grid City project saying:

In summary, this Commission believes that the Company needs to re-boot the SGC project and restore some of the promise this concept originally held. (Paragraph 23, page 7, Decision C11-0139, Colorado PUC).

Xcel has 20 days to contest the decision through the PUC appeal process.

Windsource–Xcel’s Latest Filing Still Inscrutable

Submitted by Leslie Glustrom

On December 14, 2010 Xcel filed an update on its calculation of the Windsource premium. It is attached below.

Once again, the method used to determine the Windsource premium is still largely inscrutable–particularly the first step of determining the incremental cost of the additional renewable resources. A motion describing the concern and asking the PUC to exercise its oversight on this issue is also attached below.

Xcel is expected to file a Renewable Energy Standard Compliance Plan for 2012 in the spring of 2011. This will be another opportunity to bring additional transparency to the Windsource calculation.

Xcel’s Ballooning SmartGrid Costs Get Partly Deflated at the PUC

Submitted by amyguinan

When implementation of Boulder’s SmartGrid City began in 2008, it was one of the first and most comprehensive experiments in the nation with smart-grid technology, which uses computers to manage electricity distribution and allows for communication between utilites and consumers.  At the time, the total cost for SmartGrid implementation was estimated at $100 million and Xcel’s share at $15.3 million. The remainder would be paid by companies partnering in the pilot.

By last year, however, Xcel’s share had ballooned to $44.5 million.

In an unexpected move in January, The Colorado’s Public Utilities Commission ruled Xcel could include only two-thirds of the $44.5 million cost of the smart-grid test in its rate base. The remaining $16.6 million will be off limits until Xcel can show the Boulder-based project’s benefits to Colorado ratepayers, the commission said.

“I’m struggling with how quickly those costs have escalated,” said PUC commissioner James Tarpey. Tarpey noted in testimony that an Xcel official had said that if there had been a cap on expenses, the utility would not have conducted the pilot. The message, Tarpey said, was: “Yeah, we really want to do it, but not with our money.”

Update–Windsource Transparent Recalculation Postponed

Submitted by Leslie Glustrom on December 28, 2010 – 12:50am

Many supporters of Clean Energy Action are subscribers to Xcel’s “Windsource” program. In recent years, the “Windsource” program has been modified to include not just  wind but also solar and other clean energy sources that are used to meet Xcel’s Renewable Energy Portfolio standard under Colorado law. Consequently, the quotations around the “Windsource” name reflect that “Windsource” can also be providing solar or other non-wind clean energy sources.

The cost of Windsource is approximately $2 per 100 kwh–or about 2 cents/kwh. This is close to a 20% bill impact (on a 10 cent/kwh) charge while Xcel is meeting the Renewable Portfolio Standard with less than a 2% bill impact, as called for in Colorado law. The reason why Windsource has a 20% bill impact while meeting the Renewable Portfolio Standard has only a 2% rate impact are unclear.

In Docket 09A-772E I worked hard to understand how the Windsource premium was calculated. Despite numerous questions (called “Discovery Requests”) to Xcel and many days of hearing and cross-examination, the basis for the $2 per 100 kwh charge was still completely unclear.

Both the Administrative Law Judge and the full Public Utility Commission agreed that the “Windsource” calculation was not clear and in two separate decisions Xcel was directed to recalculate the “Windsource” premium as part of its 2011 Renewable Energy Standard filing.

After the issuance of these decisions calling for Xcel to recalculate the “Windsource” premium, Xcel asked the Commission to excuse it from filing a 2011 Renewable Energy Standard plan and the Commission granted Xcel’s request. As a result, the recalculation of the “Windsource” premium in a transparent fashion has again been postponed until at least Xcel’s 2012 Renewable Energy Standard filing expected in May 2011 with testimony and hearings expected to last through much of 2011.

Xcel was directed to make a “compliance” filing of the Windsource calculation, which it did on December 14, 2010 and that filing is attached. Once again, the numbers in Attachment B of this compliance filing are completely unclear–particularly Columns 2 and 3 which are the incremental costs and the incremental GWh (Gigawatt hours) for the Windsource program–but which do not have any supporting spreadsheets or calculations.

Xcel’s compliance filing from December 14, 2010 shows (on Attachment B) that the Windsource premium should be about $1.86 per 100 kwh (instead of the $2.12 per 100 kwh that is being charged) but since the difference between the two rates is less than 20%, Xcel does not have to make a change to its “Windsource” premium.

The key decisions in the 09A-772E docket are attached and the key “Windsource” provisions are summarized below. All documents in the 09A-772E docket can be found by searching the PUC website for the 09A-772E docket number and specifying that it is for the electric industry.

Recommended Decision R10-0586 (June 11, 2010)–See Paragraph 135 on page 32 for the Adminstrative Law Judge’s decision that Xcel should recalculate the Windsource premium.

Decision C10-1033 (September 23, 2010)–See Paragraph 12 on page 5 and Paragraph 43 on page 14 for the full Commission’s decision requiring Xcel to “clearly explain how the Windsource premium is calculated”  in the 2011 Renewable Energy Standard filing.

Decision C10-1221 (November 10, 2010)–See Paragraphs 8-11 on pages 3-4 allowing Xcel to not submit a 2011 Renewable Energy Standard filing and allowing Xcel to recalculate the “Windsource” premium in a “compliance filing.” Compliance filings are not typically subject to questioning or cross-examination.

At this time it appears that it will likely be late 2011 before the Commission will once again rule on whether the “Windsource” premium has been calculated in a transparent and proper fashion.

Limits on what Xcel can charge customers for Boulder Smart Grid

Submitted by Lili Francklyn on November 10, 2010 – 6:34pm

Under the settlement Xcel would be entitled to full cost recovery from 1.4 million ratepayers across Colorado – not exceeding $44.5 million.

The utility’s SmartGridCity, originally estimated at roughly $15 million – and not to be incurred by Boulder ratepayers – has seen costs rise to more than $44.5 million since its 2007 inception.

If no protests are lodged within 20 days, the PUC will adopt the recommendation and pass the cost of Xcel’s SmartGridCity onto ratepayers.  Email the PUC with protests or complaints;
