Requesting Transparency for Transmission

Below is the text of a statement provided by Jim Windsor (retired Assistant Director of Utilities) at the City Council meeting on January 6, 2020.  If we want a more open and honest discussion of our electric service issues, we will have to continue to ask for it.

“Recently, five members of the Columbia City Council signed a letter that stated in part “we expect open, honest and transparent government.” As a citizen, I commend the concept; however, as a ratepayer of the electric utility, I question its validity.

Over 10 years ago, the first interested parties meeting regarding a new substation and the first Council work session on a proposed transmission line were held. That was followed by multiple interested parties meetings; council work sessions; reviews of multiple Option A routes; the development of Option B routes; more input from
residents; more council work sessions and discussions; a community review and
selection process; and, of course money being paid to consultants.

This lengthy process resulted in the purchase of property for the substation and the
selection of a route, called Option A, to connect the new substation with the Perche
Creek substation.

It also resulted in a bond proposal that was presented to voters in April of 2015.
Approximately half of the total bond proposal, as outlined in the information presented to voters, was related to the transmission and substation projects.The April 2015 bond proposal was approved by 68% of voters, bonds were initially sold
worth about half of the total bond authority and rate payers received a 3% rate increase to pay for the principal and interest on the bonds.

City staff moved forward with purchase of the required substation transformers and
other equipment needed to build the new substation and connect to the Grindstone and Perche Creek substations. City staff also brought forward an authorization to proceed with the transmission line.

It was at that point that a group, unhappy with the results of the lengthy public process, came to the Council in opposition to the transmission project. In January of 2016, four years ago, the Council placed the transmission line on hold. What has happened in those four years?

The mayor suggested a different route called Option E.

Burns & McDonnell was paid $100,000 for an in-depth study of Option E and that study was completed in July 2018. Public presentation to Council was part of the contract scope-of-work but never occurred. The study shows Option E would cost a minimum of $10 million more than Option A and included a list of multiple issues that could drive the cost much higher.

Quanta was hired for an electric distribution study and was also paid $100,000. That
study was completed in July 2018 and included a public presentation as part of the
contract. That presentation never occurred. The study shows that five substations
exceeded 100% of their capacity should they lose one of their transformers. Perche
Creek substation is the most in danger at 160% and that occurs at 97 degrees.

Staff sent Council a synopsis of the Quanta report after I raised the issue earlier this year. When a member of Council asked when the last time a substation transformer had failed, staff indicated it doesn’t happen often and it had been several years. That’s true, the last time it occurred was in 2012, when the summer temperature was over 100 degrees. Summers have only reached 97 since then.

The fact that the two reports were not publicly discussed can be blamed on the previous city manager. In the spirit of open, honest and transparent government, I ask the City Council and new city manager to require those consultants to complete their contracts and publicly explain their studies.

In early 2019, the Council approved the Westbury Village development which could add over 2 megawatts of load to the already overloaded Perche Creek substation. In June 2019, the Council accepted the Climate Action Plan. That plan predicts higher summer temperatures, while also encouraging switching motor vehicle fuels and natural gas equipment to electricity. It also states that more frequent extreme weather
events increase the risk of longer, sustained power outages for the City’s electric
customers.

So, after four years, where are we –

  • we have yet another citizens committee and yet another consultant with a report due in September 2020. Let’s hope this summer doesn’t exceed 97 degrees.

Reports based summer temperatures at 97 degrees, really don’t address the issue. The
real issue is “what will happen to the electric distribution system when the summer
temperature reaches 105 degrees?” That was the temperature in 2011 when the last
system peak occurred.

Since policy will be developed that is based on the climate report then perhaps the
question should be “what will happen to the electric distribution system when the
summer temperature exceeds the previous Columbia record temperature of 113
degrees?”

I look forward to open, honest, and transparent government addressing these questions.”

Vision Lights On! More on Transparency and Transmission

Following various public comment and expressions of concern, Council requested a “report on the electric capacity and load serving reliability of the Perche Creek substation” which it received at its meeting on October 7, 2019. The report does not focus on the specific loads in the area, although it notes those are being studied.  The report does note that

“There is some concern that recent load patterns may not be representative of a ‘worst-case’ for the City.  The City has not experienced extended temperatures of 105 degrees or greater since it set its all-time peak in the summer of 2011.”

Even though the report focuses on potential loss of only one transformer and does not address a complete outage at the substation, it does reference its “Load Shed Plan” for certain contingencies.  Under that plan “[r]esidential customers are targeted to be shed first while critical services such as hospitals, fire stations and the water and wastewater treatment plants are shed last.”

At least two citizens with extensive experience in the field have submitted responses to the Council pointing out issues ignored in the report. You can review those responses here (first response) and here (second response).

In other developments worth noting, the Integrated Electric Resource and Master Plan Task Force, which was appointed by the Council, issued an RFP requesting, as part of the scope of work, a review of the existing standards of reliability. This tracks the concern we noted in an earlier post that the City might look to justify the deferral of needed investment in its transmission infrastructure by simply changing the methodology traditionally used to ensure reliability.  In July of this year the Council also approved a Climate Action and Adaptation Plan (CAAP) which includes the following recommendations: (i) “moving towards 100% renewable electricity generation”, (ii) elimination of the current limits on rate increases caused by the purchase of more expensive renewable sources, and (iii) using storage batteries and community microgrids to support grid resilience and promote reliability (see pp. 48-49). The plan did not include any analysis of the costs or effects of these recommendations. The first two of these recommendations were among the CAAP priorities that were also reviewed by the Council on October 7, 2019.

So where are we going with our electric service?  Will we have an true open discussion of the trade-offs between cost, reliability, and available options or will some options like the transmission line simply remain off the table?  What is our risk tolerance?  And will we have a full accounting of the costs associated with the Council’s hasty decision to “pause” the transmission line in 2016, including an accounting of costs associated with opportunities lost when a project that was approved by the voters, on-time, and on-budget, was simply set aside.

 

Vision Lights On! Transparency, Transmission, and Summer Heat

Although the words “transparency” and “infrastructure” were used a lot in the recent mayoral election, there was little discussion of the inadequate electric infrastructure on the southwest side of Columbia. June was thankfully cool.  But as the summer heats up, the risk of outages returns.  As we have noted before, we have an aging substation serving much of the southwest side and more than one transmission line at risk (lacking needed redundancy) in the summer heat.

Most of us are used to purchasing insurance or taking proactive, protective steps when faced with a significant risk of loss.  That is essentially what voters approved in 2015 when voting for bond funds that were to be used to fix our inadequate electric infrastructure in south Columbia.  That is what the City Council was doing when it first approved the construction of a new, strategically located, substation and transmission line, and then issued bonds, and approved a related increase in rates. The new substation and connected lines were to have been finished by now.

Unfortunately, in January 2016 the Council chose to “pause” construction with no alternative plan in place.  In effect, the City Council canceled our insurance even though we have continued to pay the bills through the increased rates.  We also paid approximately $200,000 for studies which confirmed both the substation overloading and the fact that delays are costing us significantly.  Yet these studies and their implications were never publicly addressed.

Instead, the Council has added additional load by approving construction of the Westbury subdivision, sidelined our experienced staff on planning issues by referring these to a citizen commission whose members are appointed by the Council, and allowed an exodus of experienced line workers (who work to restore service when outages occur) by not paying competitive salaries. These actions only increase the risk and the need to find solutions.

What the Council does like to talk about is renewable energy.  Although renewable energy resources serve an important role in our electric system, they do not eliminate the need for investment in our transmission facilities. Ensuring adequate and reliable electric service presents many complex issues and easy answers are usually wrong. Accurate information and attention to engineering realities are needed if we are to find a way forward.

As we meet the candidates for City Manager, consider the following:  Is there a candidate who is willing to challenge the Council when it fails to consider issues that affect our health and welfare?  Or when it oversteps the bounds of our Council – Manager form of government? Or when it works to undermine our professional staff? Who is willing to talk openly and honestly to the public about both costs and risks associated with infrastructure needs and failures?  Who might move us forward?

 

Vision Lights On! Ignoring Reality

On February 4, 2019, the City Council voted for yet another development on the Southwest side. That development would place additional stress on already overloaded electric infrastructure in this part of town. Before voting, they received the warning copied below from a retired Water & Light executive.  Of course it was ignored.

Why should we be concerned about our electric infrastructure?  Keep reading! And join in Vision Lights On!

Good Morning,
Because the City Council has failed to address the electric load issue in the south part of Columbia, further development puts all southern Columbia residents at risk of outages, particularly during the summer peak season.  All development should be stopped until that issue is addressed.
I do not live in the area impacted by this overloading (or development) and I can not attend the Council meeting tomorrow night but I wanted to make you aware of this issue since it is not being addressed.
The proposed development would receive power from the Perche Substation.  That substation is loaded over 150% of design capacity.  The electric system requires redundancy.  Substations should never be loaded to the point that if one transformer fails, the load can’t be switched to another transformer.  At the Perche Substation, that point was reached several years ago and if something happens now a prolonged outage would occur.
The bond issue, that citizens passed by a large majority in 2015, would have addressed the issue by building a new substation in south Columbia; off-loading the current overloading; and, built a second transmission line to the Perche Substation (currently there is only one transmission line to Perche).  The original plan would have had the work completed by late spring 2017.
Currently there is no decision on what is to be done to address the overloading across south Columbia, yet development continues without addressing the consequences.   A study was completed several months ago that showed that the “Option E”, proposed by the mayor, would have cost nearly double the original Option A; however, that report has not been publicly discussed and nothing is being done to address the issue.
The only way this development could be serviced without attaching to the Perche Substation would be to build an “express” feeder from the Harmony Substation.  That would cost hundreds of thousands of dollars (maybe over a million) more than connecting to Perche.
I am retired now, but was responsible for forecasting electric system load.  Some Council members insist that the load hasn’t grown and therefore there isn’t an issue in southern Columbia.  There are two major flaws in that argument:
1. The historic system load occurred when the actual temperature reached 105 and the nighttime temperature never got below 80.  The recent highest summer temperatures have not exceeded 100.  Until similar high temperatures occur the actual system load can only be projected.
2. The forecast is for the “system” not for individual substations.  To be connected to the larger national grid, electric utilities have to forecast how much energy will flow into their system (transmission system) during peak conditions (subject to fines for failure).  Forecasting loads on individual substations (the distribution system) is not regulated and was not done.  As I stated previously Perche is well beyond design criteria that allows redundancy in the system.
This development should not even be discussed until the City Council addresses the electric system overloading in south Columbia.

Speak Up For Basic Services

It’s more than 72 hours since the snow started to fall on Friday and our street isn’t plowed.  Is yours?  On Friday the City reported that 7 of its plows were inoperable for “mechanical reasons”.  This morning (Monday) it reported that approximately 40 to 50% of residential streets had been cleared.  That means significant numbers were not cleared. At some point on Saturday over 8,000 people were without power.  If you have been reading the news, then you know Columbia has been losing the workers who operate garbage trucks and snowplows, and electric linemen because of a failure to pay competitive salaries.  If you have been reading this blog, then you know that the City has also been failing to make adequate investment in its electric infrastructure. And if you drive our roads you are familiar with potholes.

Every resident’s quality of life, and the economic health of our businesses, is affected by the City’s ability to effectively and affordably deliver basic services including road maintenance, electricity, water and sanitation, and trash pick up.  It’s past time for the City Council to dedicate more time and attention to our basic services.

Later this month, the City is holding three Strategic Plan Focus Groups: January 23rd, 24th, and 28th.  Those attending will be asked to comment on the City’s top priorities for its 2019-2022 Strategic Plan.  They will also be asked about policies and funding priorities.  Please consider signing up and advocating for our basic services.

All three meetings will be held at the Activity and Recreation Center, 1701 W. Ash St. at the following times.

  • Wednesday, January 23rd, dinner at 5:30 pm, focus group from 6:00 – 7:30 pm
  • Thursday, January 24th, dinner at 6:00 pm, focus group from 6:30 – 8:00 pm
  • Monday, January 28th, dinner at 6:30 pm, focus group from 7:00 – 8:30 pm

Dinner will be served, childcare will be provided, transportation is available, and each participant will receive a $25 gift card.

Vision Lights On! Revisited

As a recent report from KOMU illustrates, Columbia is stuck in infrastructure limbo with respect to needed investment in its transmission lines and substations.  The report shows the council members who helped stop Option A, and who championed and then quietly abandoned Option E, deflecting questions by misquoting Water & Light and punting to a recently established committee whose chairperson stated it was not looking at transmission needs.

As has been explained in prior posts, we do need to strengthen our electric infrastructure now and also develop a clear plan for the future.  Ignoring this issue is like putting off buying auto insurance because there hasn’t been a crash “yet”.  Citizens deserve — but have not been getting — straightforward information, ongoing updates, and solutions that will keep the electrical infrastructure of Columbia up to par.

We invite those of you who are concerned and interested in finding a solution to join us in pursuing Vision: Lights On!  Follow this blog for future updates.

Keeping An Eye On Our Electric Service

We have previously discussed the Council’s ongoing failure to address the overloading of the substations that serve the South and Southwest and also affect power downtown. The overloading has only gotten worse. In 2015 the Perche Creek substation exceeded its loading goal by 22%. In 2017, that number was 29%. In July of 2018, it was 48%. Perche Creek was not the only substation to exceed its loading goals in July. Blue Ridge, Rebel Hill, and the Power Plant all exceeded 100% of their loading goals. Hinkson Creek was at 99%.

Electric systems must have reserve capacity for times of high loads and/or problems with the system such as those caused by storms, to avoid outages. This overloading is a current issue, not one for future planning. We were lucky this year. What might have happened had we had longer stretches of extreme heat as we did in 2011?

Until put on hold by the City Council, installation of the Mill Creek substation was part of Water & Light’s contingency plan to keep the system up and running under adverse conditions. (Compare these 2016 maps which show the system without Mill Creek, and with its addition.)  Load shedding” is a focus of the current plan. This was explained to the City Council in January 2018, although it did not draw much discussion. Where would outages occur? Depending on where the load needed to be dropped, outages would start with the circuits tied to that particular substation and after that, would occur on circuits identified “from a priority or community impact relationship.” (Minutes, January 2, 2018, pp. 13 and 14.)

How would your business, residence, or our community be affected by an extended outage? Is this a risk we are willing to simply live with? If not, speak up! Electric infrastructure takes time to plan and install. We have 11 months before next summer. This is an urgent issue that needs ongoing attention.  Can we develop an action plan for Vision: Lights On!?
