Faster-than-Expected Data Center Load Growth May Cause Increased Regional Short-term Fossil Fuel Generation and Wholesale Electricity Prices

LCG, March 18, 2026--The EIA released a new "In-depth Analysis" of the potential impact of faster-than-expected near-term growth in data center power demand on power generation and wholesale prices on March 12. The analysis models the lower 48 states through 2027 and compares results to its base case scenario. Key takeaway from this sensitivity analysis is the potential increase in fossil fuels in some regions and potentially a significant increase in wholesale prices in ERCOT.

Spanish Regulators Due to Rule on Endesa-Iberdrola Deal

LCG, Jan. 10, 2001Spanish regulators were to rule today on the planned acquisition of Iberdrola by Endesa, a combination which if left alone would result in a company controlling more than 80 percent of Spain's power supply.

People familiar with the Spanish competition tribunal say that its criterion will be that the combined company control a maximum of 40 percent of the separate sectors of the country's electricity business. The companies have expressed willingness to cut back their combined generating capacity to 40 percent of the market, but they had planned to keep at least half of their 8 million retail customers and almost two-thirds of the Spanish transmission and distribution business.

In making its offer for Iberdrola, Endesa trumped a bid by Gas Natural, an affiliate of Repsol YPF, and now Repsol is the most vocal critic of the Endesa-Iberdrola combination. Repsol want the deal blocked until the companies provide a list of the businesses they are willing to divest and a timetable for disposing of them.

Endesa and Iberdrola have both said that government conditions imposed on the merger could scotch the deal if they were too severe. Iberian observers pooh-pooh such talk as rhetoric aimed at speeding up the approval.
