Information and Misinformation – 3

In this post we look at three additional claims made by members of the public who questioned the Option A transmission line route during our forums.

The first was the suggestion that W & L was investing in transmission for the benefit of Boone Electric customers. The fact is that one can’t simply eyeball the landscape and determine who is and is not a city customer. We learned that, for the last 30 years, electric service has been governed by a territory agreement between Boone Electric and the City. Although there is a section of southwest Columbia that is served by Boone Electric under that agreement, W & L is required to provide, and does provide, service to customers on either side of that section.

Representatives of W & L further explained to us that the electric distribution systems of Boone Electric and the City are not compatible. This is because they are operated at different voltages, opposite phase rotations, and different phase angles. This makes it practically impossible for the City to serve Boone Electric customers or for Boone Electric to serve City customers.

W & L representatives also noted that although growth in southern Columbia is primarily due to new residential development, there has been a lot of new commercial development as well. This includes all the businesses along Grindstone and Nifong. Some of the biggest commercial loads have been for medical centers which use use a lot of electricity for all their equipment.

The second misconception raised in the forums related to the thought that the City might be able to avoid building new transmission lines through better energy efficiency or conservation. We also asked W & L about that, and here is the response:

In the 2008/2009 time frame we greatly increased our electric efficiency programs according to the utility cost/benefit established in our Integrated Resource Plan. From 2008 through 2015, the cumulative reduction in the electric load was estimated to be 38.86 million kilowatt hours with a total peak reduction of 5,891 kilowatts.

As a result our electric load projections have been modified from a 2% annual increase to a 1.25% annual increase. Renewable resources like solar help lower the electric demand during the day but the production starts dropping off as our electric peak increases (peaks happen around 5 to 7 pm). Note that large amounts of electricity can’t be stored for an economical price.

Although energy efficiency, controlling the demand, and new solar resources are great achievements for our community, they simply won’t solve the problem of a second feed into the Perche Creek substation or the overloading we already have at our existing substations. ”

Third, we asked about the various claims, made during the forums, that “Option A” was the “most expensive” option. “Expense” is actually a complicated issue that requires consideration of different time frames, and benefits gained. W & L shared with us information (also shared with the City Council) indicating that Option A, while initially more costly in nominal dollars, also provides more capacity and resolves issues for a much longer period. That means it is lower cost, or higher value, over time.

You can review this, and other information related to the transmission line issue, on an archive webpage created by Water and Light to help keep the public informed.

  1. Thank you Jim! — first for condensing several questions and concerns into these three and then for following up and getting these responses from W & L. This helps a lot.
