Automatic summary, not yet reviewed
- The bill would require hydroelectric plant reversion files to be processed without delays: they must start three years before the concession ends and be resolved within one year at most. Lack of a decision would not allow the procedure to lapse.
- Once the plant is returned, the water authority would decide which public entity will run it under a special authorization. Profits would be publicly owned, and new concessions would have to follow the system operator's instructions and decarbonization requirements.
- The Ministry of Finance could transfer returned water rights free of charge to public entities for public utility or social interest purposes. If the plant does not exceed 5,000 kVA, it would go to the local municipality, county or province; otherwise, to the regional government.
- The bill proposes that public entities operating returned plants pay the economic activity tax on that operation, removing their usual exemption.
- Anyone who fails to remove or demolish the installations when their concession ends could not obtain new water use concessions, nor could companies in their corporate group.
- Reversion procedures already started and unresolved would be governed by the new law, and plants already returned would have one year to adapt. The law would take effect the day after publication, except for measures affecting the current budget year.
Who it affects
- Companies holding hydroelectric concessions: They would lose the plant when the concession ends, face fixed deadlines for reversion, and could be barred from new concessions if they fail to demolish the installations.
- Municipalities, provinces and regional governments: They could receive returned plants and their profits free of charge, and would report on reversion files.
- Residents of rural areas where the plants are located: Public profits should be used for the economic and social restoration of those territories.
- Electricity consumers: The bill aims to stop hydroelectric plants from being used to raise electricity prices.
