Alliant Energy, called Interstate Power and Light (IPL) in Iowa, is proposing a nearly 25 percent increase in its basic service rate. Since Alliant divides its charges to customers into energy, transmission, and basic service, the total bill increase will not be that large but it is a pretty big increase.
Since electric utilities are monopolies, some entity needs to “regulate” their actions. In Iowa this is the role of the Iowa Utilities Board (IUB), which must decide on the rate increase. The IUB can certainly reduce the proposed rate and can change the way IPL wants to charge individual customers.
Several electricity users in the Decorah area (the city of Decorah, Luther College, Winneshiek Energy District, and others). formed the Decorah Area Group (DAG) and intervened before the IUB to challenge the proposed rate increase. I wrote testimony on rate design for the DAG, and the following is the conclusion of my testimony:
It is apparent to me that IPL’s overriding desire is to sell more electricity at exactly the wrong times. The Company proposes in this case to:
• Raise the Basic Customer Charge, which is already much higher than that of the other investor-owned electric company in the state; [$13.00 compared to $8.50 charged by MidAmerican Energy. Low-income customers use less electricity so boosting this charge hits them hardest.]
• Reintroduce declining block rates during the summer peak period, which will likely cause IPL to add capacity for its system; [few utilities give large residential users a break for using more electricity in the summer and so again the smallest users — low income and conservationists are hurt again by this proposal.]
• Discourage the production of solar power, when encouraging development of solar generation might help IPL to avoid adding generation do accommodate the super peak days; and,
• Refrain from introducing a “super” off-peak rate that could redirect demand away from peak periods. [Their new meters allow them to make electricity really cheap around midnight so customers could charge electric cars or big capacity water heaters, but they aren’t doing it.]
These proposals, combined with IPL’s actions to convince the Iowa General Assembly to completely bypass the Board and greatly dismantle the state’s energy efficiency programs [in 2017], compels the conclusion that IPL wants to sell more power — not less — especially during the times of the day when IPL’s system is more costly to operate so that IPL will reap more profits.
As noted in the testimony, the Alliant/IPL proposal goes backward on both equity and energy efficiency, which are responsibilities of the IUB to ensure.
IUB’s own mission states that it “regulates utilities to ensure that reasonably priced, reliable, environmentally responsible, and safe utility services are available to all Iowans.” Note — “all Iowans.” This is IUB’s own assurance to even the least-powerful among us that they will be protected in the monopoly marketplace for electricity.
State law [476.1(5)] demands that the IUB “promote the use of energy efficiency strategies by gas and electric utilities required to be rate-regulated.” The Alliant proposal, by contrast, is a recipe for energy inefficiency.
The IUB has limited latitude to deny this rate increase. However, this rate increase is such a sweeping denial of equitable treatment of customers and a rejection of environmental responsibility that they might. The decision will only come after months of more filings and hearings. Stay tuned.
