Galp's Oil Production Surges 23% as Electricity Prices Plunge 67%

Galp Energia, Portugal's flagship oil and gas company, has reported robust operational performance for the first quarter of 2026, delivering a 23% year-on-year jump in oil and gas production to an average of 129,000 barrels per day. The company's refining margin more than doubled from $5.60 to $14.80 per barrel, significantly boosting profitability. However, the quarter also revealed a sharp tension in Galp's business model: while refining margins soared, electricity prices plummeted 67% to €23 per megawatt-hour, directly pressuring revenue from the company's renewable energy assets.

Upstream Production Climbs to Multi-Year Highs

Oil and gas extraction remains Galp's primary earnings driver. Crude accounted for 87% of total output in Q1 2026, reflecting the company's strategic focus on hydrocarbon assets. Production climbed 14% sequentially from Q4 2025, underscoring operational efficiency gains and steady performance in the company's core fields.

Galp's upstream portfolio supports stable cash flows, which the company reinvests across its business segments, including renewable energy and industrial operations.

Refining Margins Double, Boosting Short-Term Profitability

The standout performance came from Galp's Sines refinery, where margins surged to $14.80 per barrel—far above prior expectations and nearly triple the $6.90 recorded in Q4 2025. This margin expansion reflects tighter global diesel markets, reduced European refining capacity, and favorable crude oil pricing differentials.

Raw material throughput at Galp's industrial and midstream segment reached 18.7 million barrels of oil equivalent, while petroleum product deliveries hit 3.5 million tonnes, a modest 1% year-on-year decline but 16% higher than the previous quarter, signaling recovering demand as spring travel season begins.

For Portugal, the Sines complex remains the country's sole large-scale refinery and a strategic asset for fuel supply security. Stronger refining margins improve the economic viability of continued operations and support employment in the industrial corridor south of Lisbon.

Natural Gas and Electricity Sales Expand

Galp's natural gas and LNG operations recorded 18.0 terawatt-hours (TWh) in supply and trading volumes, a 42% jump compared to Q1 2025. Gas sales to end customers rose 1%, while electricity sales advanced 14%, reflecting the company's expanding retail footprint in the Iberian Peninsula.

For Portuguese households and businesses, Galp's ability to trade larger gas volumes provides supply stability and may moderate price volatility in the retail market.

Renewable Capacity Grows While Revenue Faces Headwinds

Galp's renewable energy segment reveals a core challenge facing the company. Installed renewable capacity reached 1.7 gigawatts (GW) at the end of Q1, an 8% increase year-on-year, and renewable generation sold climbed 21% to 471 gigawatt-hours (GWh). Yet the average selling price for electricity crashed 67% to just €23 per megawatt-hour, driven by surplus solar and wind generation across the Iberian Peninsula and subdued industrial demand.

This price collapse creates a direct business challenge for Galp: despite generating more renewable electricity, revenue from these assets has declined significantly. The company's strategy to mitigate this involves vertical integration, where renewable output feeds its own industrial operations, including the Sines refinery. Galp also pursues Power Purchase Agreements (PPAs) to lock in more stable prices, though the extent of hedging coverage remains undisclosed pending the full quarterly report on April 27.

What Lower Electricity Prices Mean for Portuguese Residents

The 67% collapse in wholesale electricity prices should benefit Portuguese consumers as lower wholesale rates gradually filter through to retail tariffs. However, the speed and scale of these savings depend on regulatory decisions by the Portuguese Energy Services Regulatory Authority (ERSE) and the pricing strategies of retail energy suppliers.

Lower electricity costs also create opportunities for Portugal's industrial competitiveness, potentially attracting energy-intensive manufacturing and data center investments seeking cost advantages.

Yet sustained low power prices present a challenge: they threaten the financial viability of new renewable energy projects unless developers secure long-term contracts or government support mechanisms adapt to the new market environment.

Outlook

Galp's full Q1 2026 results, due before market open on April 27, will clarify how upstream and refining strength offsets renewable revenue pressure. The coming quarter will be critical for understanding the company's strategy for balancing fossil fuel earnings with the low-margin renewable energy landscape that now defines Portugal's power market. For investors and policymakers, Galp's performance underscores the volatility inherent in Portugal's energy transition and the importance of strategic hedging and long-term contracts in a rapidly shifting market.
