Legal basis

Subsidies are provided by ewz as a public service on behalf of the City of Zurich, and for which ewz raises a surcharge on the grid usage fee (municipal levies) in accordance with the Electricity Supply Act.

Calculating your subsidy
  • The subsidy calculator lets you estimate the maximum subsidies available for a specific measure.
  • However, subsidy amounts are only binding once you submit a concrete application and receive confirmation.

The city of Zurich’s energy targets

The 2000-watt society is an energy policy vision that combines the national efficiency targets of the Energy Strategy 2050 with the international climate goals of Paris 2015. In 2008, voters in the city of Zurich agreed to commit to the targets of the 2000-watt society, taking on a pioneering role while also supporting local value creation. 

When it comes to achieving its net zero targets, the City Council focuses on measures in the city’s direct area of responsibility and action and does not use climate protection certificates. Zurich’s voters approved the new climate protection target with a clear majority of 75 per cent, and enshrined it in the municipal code.
