On Q1 investor calls, 40% of utilities see expansion opportunities driven by connecting data center load

May 7, 2025
Utilities nationwide are feeling the effects of the AI revolution. Forty percent of utility Q1 investor presentations touted load growth potential from data centers.  Many are noting inquiries from  Google, Amazon, and Meta.  Others demonstrated a track record and pipeline of new connections.  Ameren, BlackHills, Evergy, and WEC Energy have proposed special large load tariffs to accommodate these customers. One should expect similar conversations to the discussions around special tariffs for connecting cryptocurrency miners, where there has been a hesitation to build out electrical infrastructure for electrical load that may go away, leaving customers holding the bag.  Designed properly, these tariffs can work for all parties involved.  Let’s see how we sort out the competing demands for new load from both AI applications and the electrification of transport and heat.

Kicking the can down the road 

March 27, 2025

As seen on LaReg Corp’s docket tracker Kentucky Power Company (KPC, an AEP company) has filed an application with the Kentucky Public Service Commission, Case #2025-00031, requesting approval to defer approximately $11 million in extraordinary operations and maintenance (O&M) expenses resulting from two major storms on January 5 and February 15, 2025. Without this deferral, KPC would need to expense these costs in the first quarter, potentially impacting its financial metrics and credit ratings, which could lead to higher financing costs and affect customers. Similarly, Southwestern Public Service Company (SPS, an Xcel company) filed a request in Texas to defer accounting treatment of excess liability insurance expanses, docket 57856. These accounting requests were typically uncommon.

Accounting orders, offer a more expedient alternative to traditional base rate cases, which can take up to a year to conclude. For instance, in Massachusetts, NSTAR Electric Company (now part of Eversource) filed for an accounting order on November 28, 2002, in D.T.E. 02-78, to address a potential $200–$300 million write-off related to pension costs influenced by stock market fluctuations and interest rate forecasts. The Massachusetts Department of Telecommunications and Energy approved the order by December 31, 2002, allowing NSTAR to implement a pension tracker mechanism to equitably manage pension expense volatility between the utility and its customers.

AEP and Xcel’s current request aims to mitigate the immediate financial impact of the recent storm-related expenses by deferring them as a regulatory asset, subject to regulatory approval. This approach is intended to preserve the company’s financial stability and maintain favorable credit ratings, ultimately benefiting customers by avoiding potential increases in financing costs.
