Supporting the energy transition through flexibility

In recent years, the energy transition has led to a steep increase in renewable energy capacities. The growth in the number of wind farms and solar parks is accelerating, and photovoltaic panels are appearing on the roofs of more and more houses. Renewable energy production is already the largest source of electricity in many markets.

Alpiq performs very well in a still fragile market

Lausanne – Alpiq looks back on a very good 2023 financial year. The past year’s measures focusing on the core business, risk management and group management brought about the desired progress. The direct dependence on electricity prices was also significantly reduced. Despite significantly lower adjusted total revenue at CHF 8.42 billion, Alpiq increased adjusted EBITDA to CHF 1.184 billion. The company recorded an adjusted net income of CHF 820 million. Operating liquidity remains extremely solid at CHF 1.944 billion and Alpiq was net cash positive of CHF 347 million by the end of 2023.

How Alpiq understands sustainability

Sustainability is embedded in Alpiq's purpose and the company is well positioned – thanks to our electricity production from renewable energies and the management of renewable energies for third parties. However, we’re fully aware that further steps are needed to build a truly sustainable company. In this interview with Karin Manser, Lead Sustainability at Alpiq, we discuss Alpiq's sustainability goals and the sustainability reporting requirements for companies resulting from the European Union’s new Corporate Sustainability Reporting Directive (CSRD).

Energy efficiency

Efficiency is a key pillar of Switzerland's energy policy. Alpiq has long been promoting energy efficiency: the company is investing several hundreds of millions of francs in efforts to ensure efficiency in electricity production, consumption and research.

Efficiency enhancements in power plants result in energy for 2,000 households

For years Alpiq has been committed to energy efficiency, with particular emphasis on innovative solutions for the generation, conversion and transmission of electricity.

In terms of electricity generation, Alpiq's main priority is to improve the yield of existing power plants. A contemporary example is the Flumenthal run-of-river power plant on the River Aare near Solothurn, which between now and 2009 is being fitted with three new higher-yield turbines. After the upgrade, the plant will be able to generate an additional 8 million kWh of electricity per year, enhancing efficiency by six percent. That equates to the electricity needs of around 2,000 households.

Alpiq's Energy Services segment is also concentrating heavily on services aimed at optimising energy consumption. Some 6,000 employees in this segment are directly or indirectly involved in the field of energy efficiency. They make an important contribution to the effective and sustainable use of energy in the fields of building and process control technology, plant construction and energy technology.

As a member of the Swisselectric research pool, Alpiq is also actively involved in the quest for new solutions for rational energy deployment. The pool invests CHF 5-10 million a year in promising, forward-looking projects.

Modernisation promotes efficiency

Over the past 10 years Alpiq has invested a total of CHF 370 million in modernising the Gösgen canal power plant, rebuilding the Ruppoldingen hydroelectric plant, and renovating the Flumenthal plant. This has increased average annual energy production volumes from 447 to 563 million kWh: a rise of more than 25 percent.

Research projects run by Swisselectric Research, in which Alpiq participates:

 

  • Optimisation of Pelton turbines (HTA Lucerne)

  • Optimisation of ventilation systems in hydroelectric plant pressure lines (ETH Zurich)

  • Optimisation of guidelines for energy security(ETH Zurich)

  • Measures against the silting up of reservoirs (EPF Lausanne)

  • Influence of extreme climatic conditions on energy infrastructures(EPF Lausanne)

  • Promotion of energy wood deployment in Switzerland (PSI)

Further information

Nant de Drance

The machine cavern with six turbine groups, each with an output of 150 MW, forms the heart of the Nant de Drance pumped storage power plant. Prior to the installation of the machinery, the cavern’s huge dimensions were already a striking sight: 194 metres long, 32 metres wide and 52 metres high. It is located 600 metres deep inside the mountain and can be accessed from the outside via a 5.6-kilometre tunnel. Alongside the power plant cavern lies the transformer cavern. It is somewhat smaller and houses the six transformers and the gas-insulated switching station for the connection to the 380 kV electricity grid.
