Climate Delegated Act Energy NACE D35.11NACE F42.22

Electricity generation from hydropower

Construction or operation of electricity generation facilities that produce electricity from hydropower.

The economic activities in this category could be associated with several NACE codes, in particular D35.11 and F42.22 in accordance with the statistical classification of economic activities established by Regulation (EC) No 1893/2006.

Substantial contribution

This activity can make a substantial contribution to the following objective(s). The activity must also pass DNSH assessment against the remaining five objectives.

✓ Climate mitigation

The activity complies with either of the following criteria:the electricity generation facility is a run-of-river plant and does not have an artificial reservoir;the power density of the electricity generation facility is above 5 W/m2;the life-cycle GHG emissions from the generation of electricity from hydropower, are lower than 100gCO2e/kWh. The life-cycle GHG emissions are calculated using Recommendation 2013/179/EU or, alternatively, using ISO 14067:2018(179), ISO 14064-1:2018(180) or the G-res tool(181). Quantified life-cycle GHG emissions are verified by an independent third party.

✓ Climate adaptation

1. The economic activity has implemented physical and non-physical solutions (‘adaptation solutions’) that substantially reduce the most important physical climate risks that are material to that activity.2. The physical climate risks that are material to the activity have been identified from those listed in Appendix A of the applicable Delegated Act by performing a robust climate risk and vulnerability assessment with the following steps:screening of the activity to identify which physical climate risks from the list in Appendix A of the applicable Delegated Act may affect the performance of the economic activity during its expected lifetime;where the activity is assessed to be at risk from one or more of the physical climate risks listed in Appendix A of the applicable Delegated Act, a climate risk and vulnerability assessment to assess the materiality of the physical climate risks on the economic activity;an assessment of adaptation solutions that can reduce the identified physical climate risk.The climate risk and vulnerability assessment is proportionate to the scale of the activity and its expected lifespan, such that: for activities with an expected lifespan of less than 10 years, the assessment is performed, at least by using climate projections at the smallest appropriate scale;for all other activities, the assessment is performed using the highest available resolution, state-of-the-art climate projections across the existing range of future scenarios(253) consistent with the expected lifetime of the activity, including, at least, 10 to 30 year climate projections scenarios for major investments. 3. The climate projections and assessment of impacts are based on best practice and available guidance and take into account the state-of-the-art science for vulnerability and risk analysis and related methodologies in line with the most recent Intergovernmental Panel on Climate Change reports(254), scientific peer-reviewed publications and open source(255) or paying models.4. The adaptation solutions implemented:do not adversely affect the adaptation efforts or the level of resilience to physical climate risks of other people, of nature, of cultural heritage, of assets and of other economic activities;favour nature-based solutions(256) or rely on blue or green infrastructure(257) to the extent possible;are consistent with local, sectoral, regional or national adaptation plans and strategies;are monitored and measured against pre-defined indicators and remedial action is considered where those indicators are not met; where the solution implemented is physical and consists in an activity for which technical screening criteria have been specified in this Annex, the solution complies with the do no significant harm technical screening criteria for that activity.

Do No Significant Harm criteria

To be taxonomy-aligned, this activity must not significantly harm any of the five objectives it does not substantially contribute to.

Water and marine resources

1. The activity complies with the provisions of Directive 2000/60/EC, in particular with all the requirements laid down in Article 4 of the Directive.2. For operation of existing hydropower plants, including refurbishment activities to enhance renewable energy or energy storage potential, the activity complies with the following criteria:2.1. In accordance with Directive 2000/60/EC and in particular Articles 4 and 11 of that Directive, all technically feasible and ecologically relevant mitigation measures have been implemented to reduce adverse impacts on water as well as on protected habitats and species directly dependent on water.2.2. Measures include, where relevant and depending on the ecosystems naturally present in the affected water bodies: measures to ensure downstream and upstream fish migration (such as fish friendly turbines, fish guidance structures, state-of-the-art fully functional fish passes, measures to stop or minimise operation and discharges during migration or spawning);measures to ensure minimum ecological flow (including mitigation of rapid, short-term variations in flow or hydro-peaking operations) and sediment flow;measures to protect or enhance habitats.2.3. The effectiveness of those measures is monitored in the context of the authorisation or permit setting out the conditions aimed at achieving good status or potential of the affected water body.3. For construction of new hydropower plants, the activity complies with the following criteria:3.1. In accordance with Article 4 of Directive 2000/60/EC and in particular paragraph 7 of that Article, prior to construction, an impact assessment of the project is carried out to assess all its potential impacts on the status of water bodies within the same river basin and on protected habitats and species directly dependent on water, considering in particular migration corridors, free-flowing rivers or ecosystems close to undisturbed conditions. The assessment is based on recent, comprehensive and accurate data, including monitoring data on biological quality elements that are specifically sensitive to hydromorphological alterations, and on the expected status of the water body as a result of the new activities, as compared to its current one. It assesses in particular the cumulated impacts of this new project with other existing or planned infrastructure in the river basin.3.2. On the basis of that impact assessment, it has been established that the plant is conceived, by design and location and by mitigation measures, so that it complies with one of the following requirements: the plant does not entail any deterioration nor compromises the achievement of good status or potential of the specific water body it relates to;where the plant risks to deteriorate or compromise the achievement of good status/potential of the specific water body it relates to, such deterioration is not significant, and is justified by a detailed cost-benefit assessment demonstrating both of the following:the reasons of overriding public interest or the fact that benefits expected from the planned hydropower plant outweigh the costs from deteriorating the status of water that are accruing to the environment and to society;the fact that the overriding public interest or the benefits expected from the plant cannot, for reasons of technical feasibility or disproportionate cost, be achieved by alternative means that would lead to a better environmental outcome (such as refurbishing of existing hydropower plants or use of technologies not disrupting river continuity).3.3. All technically feasible and ecologically relevant mitigation measures are implemented to reduce adverse impacts on water as well as on protected habitats and species directly dependent on water.Mitigation measures include, where relevant and depending on the ecosystems naturally present in the affected water bodies:measures to ensure downstream and upstream fish migration (such as fish friendly turbines, fish guidance structures, state-of the-art fully functional fish passes, measures to stop or minimise operation and discharges during migration or spawning);measures to ensure minimum ecological flow (including mitigation of rapid, short-term variations in flow or hydro-peaking operations) and sediment flow;measures to protect or enhance habitats.The effectiveness of those measures is monitored in the context of the authorisation or permit setting out the conditions aimed at achieving good status or potential of the affected water body.3.4. The plant does not permanently compromise the achievement of good status/potential in any of the water bodies in the same river basin district.3.5. In addition to the mitigation measures referred to above, and where relevant, compensatory measures are implemented to ensure that the project does not increase the fragmentation of water bodies in the same river basin district. This is achieved by restoring continuity within the same river basin district to an extent that compensates the disruption of continuity, which the planned hydropower plant may cause. Compensation starts prior to the execution of the project.

Documentation typically required

  • Impact assessment — For new hydropower plants: must assess all potential impacts on water body status and protected habitats/species, considering migration corridors, free-flowing rivers, etc., based on recent, comprehensive and accurate data including biological quality elements and cumulated impacts.
  • Cost-benefit assessment — For new hydropower plants where risk of deterioration: must demonstrate overriding public interest or benefits outweigh costs, and that no technically feasible or proportionate alternative exists with better environmental outcome.
  • Authorisation or permit — For both existing and new plants: sets out conditions aimed at achieving good status or potential of affected water body, and includes monitoring of effectiveness of mitigation measures.
  • Monitoring reports — For both existing and new plants: monitoring the effectiveness of mitigation measures (e.g., fish migration, ecological flow, habitat protection) in context of authorisation or permit.
