Audit Supervision audit - Swiss Federal Office of Energy, Federal Inspectorate for Heavy Current Installations

The supervisory and inspection area of the Federal Inspectorate for Heavy Current Installations (ESTI) covers all electrical installations and products outside the remit of the Federal Office of Transport (FOT). ESTI's tasks focus on the Swiss electricity grid with a total value of over CHF 21 billion, which was equivalent to just under 3% of Switzerland's GDP in 2022.

Audit Critical infrastructure protection – Supervision of water retaining facilities - Swiss Federal Office of Energy

There are risks associated with the operation of water retaining facilities. In Switzerland, a sound legal framework ensures the regulation and supervision of water retaining facilities and the clear allocation of responsibilities. The Federal Department of the Environment, Transport, Energy and Communications (DETEC) is responsible for ensuring that water retaining facilities achieve an accepted level of safety. DETEC delegated the operational technical safety supervision to the Swiss Federal Office of Energy (SFOE). Specifically, this task is performed by the Supervision of Dams Section, which is part of the Supervision and Safety Division.

Audit Effectiveness of subsidies for large photovoltaic installations - Swiss Federal Office of Energy

In order to achieve its targets in terms of energy and climate policy, the Confederation has taken measures to substantially increase electricity production by means of photovoltaics (PV). Photovoltaics are to replace nuclear power as the most important pillar of Swiss electricity production, along with hydropower, by 2050. The production targets for solar electricity have been raised several times, while the measures have been repeatedly modified. Since 2014, the non-recurrent remuneration for photovoltaic installations, designed as an investment contribution, has gradually replaced the cost-covering remuneration for feed-in to the electricity grid (CRF), which has been paid out since 2009, as the most important subsidy for solar power. By the end of 2022, a total of CHF 1.5 billion in subsidies from the grid supplement fund was granted under non-recurrent remuneration for 130,000 PV installations, with an annual production of 2.6 terawatt hours. Furthermore, federal regulations are driving additional financial incentives and the legal possibilities for more solar power plants. These include, in particular, regulations on self-consumption of the solar power produced, on feeding back to the electricity grid operators and on spatial planning. Mandatory PV for new buildings, information measures and federal and cantonal tax regulations, as well as supplementary subsidies from individual cantons and communes, also have an impact on the increase in the number of solar power installations.
