Residential electricity consumers choosing fixed (blue)tariffs doubled during 2025, according to RAAEY data.
Specifically, residential meters with fixed tariffs were 867,161 in January last year (14.72% of the total) and increased to 1,653,984 in December (27.83% share). This means that more consumers chose the predictability and protection from price fluctuations that fixed tariffs provide.
The majority of consumers moved to blue, abandoning green tariffs which fell to 3,446,037 (57.98%) from 4,140,451 at the start of the year (70.26%). Despite the significant reduction, green tariffs still cover the majority of consumers. Yellow (floating) tariffs also suffered smaller losses and were reduced to 14.19 % of the market , down from 15.02 % at the beginning of the year.
From the RAEY data it also emerges that PPC remains by far the largest supplier, maintaining its 2024 share in terms of cash flow (71.84 % last year from 71.65 % in 2024).
– In the low trend PPC’s share was 70.96 % (followed by Protergia with 8.78 %, Zenith with 4.85 % and Heron with 4.67 %).
– In the medium trend PPC’s share was 52.54 % (Protergia: 18.11 %, Heron: 11.53 %, NRG: 5.46 %).
– In the high trend (large companies) PPC has 54.99 % followed by METLEN (16.33 %) and Heron (13.07 %).
Different is the picture of the shares according to the volume of consumption: in the low and medium trend PPC remains first with 60.99 % and 34.04 % respectively, while in the high trend METLEN has the largest share with 52.06 %.
In 2025 there is also a significant decrease in the number of consumers in universal service status, which was over 170,000 at the end of 2024 and was reduced to 85,000 in December 2025.
