AEP Electric Rates

AEP Ohio

On April 3rd 2024, AEP Ohio received approval of its Electric Security Plan (ESP) from the Public Utilities Commission of Ohio (PUCO). The ESP outlines AEP Ohio's commitment to continue making reliability-focused improvements to the electric grid, support economic development, and create new programs that allow customers to manage their energy use and save money. The order also makes enhancements to the Standard Service Offer (SSO) auction process. These process changes are designed to produce more stable generation rates for customers who do not choose an energy supplier or who do not participate in a governmental aggregation program. Based on recent auction results, customers who receive their power supply through the SSO will see a reduction in the generation portion of monthly electric bills by approximately $30 beginning on June 1st.

Kentucky Power

An order was issued by the Public Service Commission on January 19, 2024, which approved a partial rate increase in the Kentucky Power rate case (2023-00159). Kentucky Power was granted an Order by the Kentucky PSC on January 10 for the securitization portion of their pending rate case. Securitization is beneficial for customers since it spreads approved costs over a more extended period and at lower financing costs. The process of securitization takes a few months to implement, and customers will not see the new securitization financing line item on their bill until later in the year. The expected impact from the recent Kentucky rate case, effective for billing on and after January 24, 2024, is a 12-13% increase.

Public Service Company of Oklahoma (PSO)

Recovery of February 2021 storm costs through a rider will cause customers to see an increase of approximately 2% - 3% spread over 20 years.

PSO filed and has received approval of updated fuel rates with the Oklahoma Corporation Commission that will be effective in May 2024. The total bill increases for this change range from 5 - 12% for commercial and industrial customers. This update represents a FCA (Fuel Cost Adjustment) rider rate period of May through October 2024, and includes actual FCA expense through February 2024 with forecasted costs for March through October and this adjustment reflects market conditions.

Drivers for the factor change include:

• FCA rates include $124.8M under-recovered balance compared to $87.6M included in current FCA rates (prepared in August 2023), the increase due in part to the extremely cold temperatures experienced in January. The under-recovery balance is being amortized to be fully recovered by the end of 2024 rather than the end of this rider rate period.
• Rider rate period includes benefit of $45.8M for Production Tax Credits (PTC's) grossed up for taxes, and $9.2M of Renewable Energy Credits (REC's) from PSO's portfolio and purchases of wind and renewable resources. The Rock Falls wind facility and associated renewable benefits is included in this forecast beginning in August 2024 to coincide with interim rates in PSO's current base rate Case No. PUD 2023-000086.

On November 3, 2023, the Oklahoma Corporation Commission (OCC) approved new rates for PSO customers. The new rates are effective with the first billing cycles in January 2024 and replace interim rates that began May 22, 2023. New fuel factors announced in November 2023 are also effective with January 2024 billing. PSO national customers can expect a combined billing reduction estimated at 13-19% beginning in January 2024.

The Oklahoma Corporation Commission (OCC) approved the Public Service Company of Oklahoma's (PSO) Fuel-Free Power Plan (FFPP), allowing PSO to add 995.5 megawatts of energy to its generation mix on May 5, 2023. As a result, PSO customers will see their monthly bills go down starting in early 2026.

Southwestern Electric Power Company (SWEPCO)

In September 2023, the Louisiana Public Service Commission (LPSC) approved SWEPCO's request to complete its Advanced Metering System deployment plan. The LPSC approved an AMS surcharge for customers that is effective beginning on September 28, 2023. The monthly surcharge for commercial and industrial rate classes is $6.40 and expires after four years. Deployment of smart meters will continue across the state through 2025.
