Commentary: Self-consumption is the logic of the new electricity system

The logic of a decentralized electricity system points towards maximizing self-consumption, where power is used as close to its production point as possible. This principle minimizes transport losses, alleviates strain on existing grids, and incentivizes investments in energy storage and flexible consumption. The article contends that Switzerland should align its grid cost allocation with where these costs actually originate.

Recent debates, partly fueled by Axpo's Energy Reports, have labeled self-consumption as a "hidden subsidy." However, the article argues that Axpo's analysis primarily describes a tariff effect rather than direct state funding. It highlights that all energy forms are subject to political frameworks and steering mechanisms. Axpo's own analysis indicates that large solar installations require the least support, with wind, photovoltaics, and nuclear power needing comparable levels of assistance for winter energy production.

The core question, according to the commentary, is not whether the energy system should be steered, but rather who should benefit from this steering. The author advocates for a market-oriented energy policy that empowers millions of private investors in solar technology, storage, and grid management, rather than concentrating market power in a few large, capital-intensive projects. This approach keeps a significant portion of value creation within Switzerland.

New photovoltaic and wind installations are among the most cost-effective forms of new electricity generation globally. By having private actors and companies bear the investment costs, the burden on the state and energy providers is reduced. Photovoltaics, in particular, offer advantages due to their scalability, ease of installation, and ability to generate power precisely where it is needed. The article draws a parallel between self-consumption and classic efficiency gains, noting that no one considers LED lamps a hidden subsidy despite their reduction in grid power consumption. Similarly, reducing grid reliance through efficient appliances, insulation, or solar power should not be misconstrued as undue support.
