Competition between electricity suppliers in the mid-voltage category was, contrary to the low-voltage category, intense in 2022, as highlighted by the significant market share contraction of power utility PPC, down to 36.01 percent in November after starting the year at 42.36 percent, in the mid-voltage category.

The overwhelming majority of companies in Greece belong to the mid-voltage category. Besides reduced electricity usage in the second half of the year, the significant drop in electricity demand in the mid-voltage category may also be attributed to company closures during the energy crisis.
