The Incentive System for Climate and Energy Transition (SITCE) – Decarbonisation and Energy Efficiency aims to support the reduction of energy consumption and greenhouse gas (GHG) emissions, namely through the replacement, adaptation, or introduction of low-carbon equipment, processes, and technologies, and, complementarily, the incorporation of renewable energy sources. This programme is an integral part of Portugal's commitment to the goals of the National Energy and Climate Plan 2030 (PNEC 2030), which aims to achieve carbon neutrality by 2050.
The framework of eligible actions is divided into two distinct modalities, depending on the nature, dimension, and structuring impact of the investment on the national economy:
Individual energy efficiency and corporate decarbonisation operations aiming to reduce energy consumption and greenhouse gas (GHG) emissions are eligible.
The notice covers two main types of intervention:
Eligible costs include the total investment costs or the extra costs necessary to achieve a higher level of energy efficiency or environmental protection, divided into the following categories:
Eligible costs only insofar as they contribute to environmental protection/decarbonisation objectives:
Application Date
Note on the Aid Request Registration (RPA): Beneficiaries who registered the aid request through Notice no. 03/RPA/2025 (of 10 February 2025) may submit the application using the operation data registered therein. The registration may only be used in a single application and the operation must correspond to what was presented in the request, barring justified changes.
Approval and maintenance of the incentive depend on compliance with specific indicators, divided into Output (physical) and Result (impact).
Measure the immediate physical realisation of the investment:
Measure the effective environmental and energy impact, determined through ex-post audit (year following completion):
Projects must meet at least one of the following mandatory targets:
Are there additional required indicators?
Yes, projects must provide estimates for the following:
Economic indicators, such as cost per ton of CO₂ avoided.
A medium-level renovation refers to interventions that enable a 30% to 60% improvement in energy efficiency in the targeted building or facility. The classification follows the criteria set out in Recommendation (EU) 2019/786 and requires:
The reduction in emissions is measured in tons of CO₂ equivalent per year (tCO₂e/year). To this end, the company must provide:
No, investments in renewable energy sources must be complementary to other project investments. The focus of this funding typology is to support the reduction of energy consumption and greenhouse gas (GHG) emissions through the replacement, adaptation, or introduction of low-carbon equipment, processes, and technologies.
However, while investments in renewable energy sources (such as photovoltaic or solar thermal systems) are not mandatory, they do contribute to the decarbonization goal and can increase the project’s evaluation score. In many cases, they help complement emission reductions or reduce dependence on fossil fuel sources.
Equipment powered by fossil fuels, including natural gas, is not eligible.
The regulations also exclude investments that result only in shifts within fossil fuels (e.g., from coal to natural gas), or that do not represent an effective and additional reduction in emissions. The focus is on:
