In 2018, the volume of electricity supplied was on average 2% higher than in the previous year.
Volume picked up in groups B and G, mainly due to a higher number of customers. Meanwhile, volume in group C declined. The increase in the volume sold was accompanied by a slight decline in the average distri-bution rate by approx. 1% yoy.
At the end of 2018, the Energa Group’s SAIDI (planned and unplanned incl. catastrophic) was 57% lower than in the previous year. Also SAIFI was lower than in the previous year, having declined by 29%. This considerable improvement of the indicators was an effect of mass failures, in particular cata-strophic storms, that took place in August 2017, as well as the cyclones Xaver and Greg, which caused the deterioration of indicators in 2017.

Gross electricity production (TWh)
The generating assets of the Energa Group produced 3.9 GWh of electricity in 2018 vs. 4.3 GWh in the same period of the previous year (-9%). This involved basically all types of sources owned by the Group (with the exception of photovoltaics).
It should be noted that with respect to the production of renewable electricity, the downward trend in 2018 is a consequence of the high reference base until 2017. The generation of energy by run-of-river power plants is an effect of hydrological conditions, while the level of wind power production was caused by the prevailing weather conditions. The production level at the Ostrołęka power plant was determined by must-run operation for the Transmission System Operator in Poland. Production of energy by the CHP plants of the Group is determined by the production of heat, which depended mostly on the demand for heat from local customers of the Group.
In 2018, the Group generated 3,928 TJ of heat, which was attributable a range of factors, including air temperatures determining the demand for heat from the Group’s local suppliers
In 2018, the total volume of electricity sold by the Sales Business Line did not change considerably relative to 2017, in the aftermath of a decline in retail sales by 4% (or 0.8 TWh) and the parallel increase in wholesale volume by 25% (or 0.8 TWh) compared to the previous year.
