Flexible depreciation

Source: International Energy Agency
Last updated: 11 September 2019
Since 1977, investment in various types of systems intended to save energy or produce electricity in cogeneration units has been eligible for accelerated depreciation (depreciation over 12 months since 1991). This is equivalent to a subsidy of 2 to 5%, depending on the useful life of the installation.
