Electricity consumers are increasingly shifting away from variable pricing in favor of long-term cost certainty, driving a rapid expansion of fixed-price electricity supply contracts over the past year. The pace of switching has accelerated to around 73,000 new fixed-rate agreements per month, putting the market on track to approach two million contracts in early 2026.
This trend has proven remarkably resilient, even during periods when adjusted green tariffs have become cheaper or remained unchanged. December offered a clear illustration, as fixed-price options continued to gain market share despite stable variable pricing, signaling a structural change in consumer behavior rather than a short-term response to price fluctuations.
Data published by the national energy regulator RAAEY show that blue tariffs exceeded 1.5 million contracts during the first ten months of the year, accounting for nearly 26% of the market. Major suppliers now expect fixed-price plans to reach around 1.7 million contracts by year-end and to surpass two million in the first quarter of 2026.
The contrast with last year is striking. Just twelve months ago, fixed-rate electricity contracts barely exceeded 800,000. As these products expanded rapidly, variable green tariffs moved in the opposite direction, steadily losing customers. Providers forecast that green variable contracts will decline to around 3.4 million by the end of 2025, down from 4.3 million in December 2024.
Over the past year alone, nearly 900,000 customers have exited green variable plans — a monthly outflow almost identical to the inflow into fixed-price contracts. This parallel movement highlights a clear substitution effect, as households and businesses increasingly trade pricing flexibility for predictability.
By the end of the year, fixed-price electricity deals are expected to command close to 28% of the market, more than double their share a year earlier. December’s figures reinforced the momentum, underscoring that consumers now place greater value on stable bills than on the potential short-term savings offered by fluctuating tariffs.
