Bulgarian nuclear power plant Kolzoduy recorded net profit of 307 million levs (157 million euro) in the first half of 2023, compared to 1.7 billion levs a year earlier, as the market price of electricity halved.
NPP’s revenue from electricity sales declined to 1.3 billion levs in the first six months from 2.7 billion levs in the same period last year, the company said in a financial statement.
At the same time, the nuclear power plant generated 8.06 TWh of electricity, 4% lower compared to H1 2022, due to a longer outage downtime at Unit 5 and an unplanned shutdown of Unit 6 in April for preventive maintenance.
NPP Kozloduy sold 7.68 TWh of net power output to the national grid, with about 34% of that going to public supplier National Electricity Company (NEK) at regulated prices. Other remaining quantities were sold on the organised market run by the Independent Bulgarian Energy Exchange, IBEX, and on the balancing market.
First-half sales at unregulated prices, including those on the organised market run by the Independent Bulgarian Energy Exchange (IBEX) and on the balancing market, totalled 5.98 TWh.
The average sales price of the electricity generated by NPP Kozloduy and sold on all markets amounted to 163.86 levs per MWh in the first six months, which is 51% less than in the same period of 2022.
Planned investment costs for reconstruction of facilities amount to 887 million levs for the period 2023-2027, with 70% allocated to enhancing safety and improving the operations and equipment of facilities, according to the financial statement.
