This Monday, the electric market shows a modest recovery, with prices hovering just above 251 euros per megawatt hour, driven by adjustments paid by gas cap beneficiaries based on wholesale market auction results and aimed at reimbursing facilities relying on this energy.

It marks the fourth consecutive rise that breaches the 200 euro per MWh level, reflecting data compiled by Efe and stands as the highest value since late September, approaching the mid to high 290s per MWh range.

Data from the Iberian Electricity Market Operator and the Iberian Gas Market indicate that the wholesale electricity price translates into the consumer rate for those on regulated tariffs. In this context, prices are about 10 euros lower than the 261.38 euros per MWh that would apply without the gas cap.

As investigations continue into Baltic Sea gas pipeline incidents and the broader energy market tensions echo across major European economies, demand dynamics remain a key driver this week. The situation contributes to ongoing volatility in wholesale prices and consumer expectations.

Leaders of the European Union are scheduled to discuss critical infrastructure security at the upcoming informal summit in Prague on October 6 and 7, underscoring the geopolitical backdrop to energy pricing.

On Monday, the market averages around 346.73 euros per MWh for electricity, with notable regional variations. In Italy prices show a rise in the 20:00 to 21:00 window, while France experiences peaks near 466 euros and around 209.35 euros in the late afternoon. In Germany, similar dynamics apply, and within Portugal, where gas caps also influence generation costs under the Iberian exception, the price aligns with Spain due to shared market conditions. Outside the European Union, prices could reach approximately 256 euros per MWh when translated from pounds.

If the analysis focuses solely on wholesale auction results, excluding the gas cap adjustment, the MWh price would revert to roughly 200.38 euros, highlighting the impact of policy interventions on perceived wholesale costs.

Time-of-day effects remain pronounced, with the highest prices typically posted between 20:00 and 21:00 and the lowest observed in the early afternoon window, roughly between 15:00 and 16:00, depending on hourly demand and supply conditions, yielding a broad spread in euro per MWh.

The gas price adjustments tied to the system’s needs vary with volume requirements and have downstream effects on households and businesses that participate in regulated tariffs. Monday’s estimated average adjustment stands near 50.86 euros per MWh, producing a final consumer price around 251.24 euros per MWh, which is roughly 35 percent higher than the first Monday in October of the previous year.

This overview reflects ongoing market mechanics and policy responses shaping consumer costs in the Iberian region and its connected markets, with ongoing analyses from market operators and energy authorities informing settlements and forecasts for the week ahead.
