For the first 18 days of September the production and consumption are slightly below than planned. An exceptional work of coal thermal power plants in August
Production and consumption of electricity for the first 18 days of September were balanced, a bit less than planned, but there was no problem when meeting the needs.
According to the data for electricity trade provided by the EPS Headquarters, the total production for 18 days amounted to 1,6 billion kWh, which is by 2,5 % less than it was determined by electric power portfolio, and the sale to final customers with full supply amounted to 1,4 million kWh or 3,6 % less than planned. The fact that 134 million kWh was sold on the free market indicates that the EPS plants met all the needs for electricity in this period.
Moderate temperature, with mean values (18,6 degrees Celsius) 1% higher than average, although mornings were cold, had an impact on electricity consumption in September. Coal-fired TPPs defined a great deal of the total production output producing about 1,4 billion kWh, which is in accordance with the plan. However, run-of-river hydro power plants produced a little bit more than planned, although the inflow of the Danube was at the planned level. Coal-fired TPPs had a good work performance. Reservoir hydro power plants (with HPP ”Piva”) produced 50 % less than planned, which means that the rationalization of the reservoir lake energy sources usage has started in order to be preserved for winter consumption.
Mr. Jovica Vranić, director of the Energy Management and Planning Sector in the EPS Department for Trade, says that in the first 18 days of September the production was mostly in accordance with the plan. Slight production plan deviation resulted as a consequence of slight deviations in production. According to him, the consumption wasn’t increased by large external temperature variations in September, when those variations are usually small.
Taking into consideration all achievements in August, Mr.Vranić pointed out that in August the temperature was by 3,3 degrees higher than the average temperature for August for the last 120 years, which kept the consumption at the planned level. However, he reminded that the first ten days of August were extremely hot, with an average daily temperature of about 29 degrees 8th August was the hottest (32,2°C), when also the largest full supply sale was achieved, i.e. 87,2 million kWh. On that day, the largest August electricity consumption was recorded. After the first 10 days, the temperature dropped to average or even below average values at the end of the month, so the need for full supply, at the monthly level, was slightly higher than planned.
The total August electricity production amounted to 2,86 billion kWh, which is 6.7 % more than planned. During that month, coal-fired TPPs had extremely reliable operation and they provided 2,36 billion kWh to the system, which is 13.2 % more energy than planned. Significantly reduced flow on the Danube decreased the total output of run-of-river hydro power plants, so that they produced only 425 million kWh, which is more than 18 % lower than the planned production of these power plants for the 8th month of the year. Reservoir hydro power plants over-fulfilled the plans by 23 % and they delivered 127 million kWh to the system.
Mr. Vranić particularly points out that in August 362 million kWh was sold on the free market i.e. 196 million kWh more than planned. He says that this has been achieved thanks to significant availability and extremely reliable operation of coal-fired TPPs, but also thanks to bigger amounts of coal in TENT A and TENT B stockpiles than it was planned, at beginning of August.
