Less precipitation, hydropower reserve and system stability
All plants managed by Alpiq in Switzerland and other countries either met or even exceeded expectations relating to technical and commercial availability. This availability provided the basis for very successful asset trading. Alpiq made optimum use of its power plants and their flexibility on the market in the past year and thus contributed to the security of supply and to system stability.
The Switzerland business division made a substantial contribution to the high availability of the plants. And this in a very challenging year that was heavily impacted by lower inflows on account of less precipitation. Nevertheless, the extraordinarily strong inflow of melt water from the glaciers melting in the summer heat and the forward-looking water management meant that we recorded good fill levels in most of the reservoirs in Valais in autumn. The high production volumes from the stable and reliable nuclear power plants Gösgen and Leibstadt almost compensated for the lower supply volumes from France. The participation in the auction for the hydropower reserve and the associated shift of a production volume of 218 GWh into the current year reduced earnings in favour of 2023. Overall, the business division closed the year with adjusted results of operations of CHF 3 million, only marginally below the previous year (CHF 7 million).
The International business division generated an excellent adjusted result of operations of CHF 134 million (previous year: CHF -17 million). Key factors here were the high reliability of our flexible gas power plants in Italy, Spain and Hungary in combination with high prices. Our forward-looking action in the customer business also contributed to the strong result. The high availability of our power plants (renewable and combined gas-fired) made a substantial contribution to system stability and to the security of supply in the respective countries.
The Trading business division managed Alpiq’s well-balanced power plant portfolio in an optimal way, used it efficiently and thus played a major role in liquidity management during this very challenging year. It increased its contribution to the adjusted results of operations by CHF 49 million to CHF 387 million. The high volatility of prices and the unpredictable availability of power plants and raw materials alike demanded extraordinary efforts from the various trading desks.
