Clean energy, generated by CGH Enxadrista, for Paraná and Brazil.
A company with a single purpose.
Energética Rio das Pedras SPE Ltda. is a Brazilian privately held company, funded entirely by private capital.
The abbreviation “SPE” stands for Sociedade de Propósito Específico — the Brazilian equivalent of a special purpose vehicle (SPV). As such, the company exists for a single purpose: the construction and operation of CGH Enxadrista. It has no other businesses, activities, or lines of operation.
This structure is deliberate. It reflects how our group organizes its infrastructure projects: each asset is held by its own entity, with dedicated governance and management.
The abbreviation “CGH” stands for Central Geradora Hidrelétrica, the Brazilian designation for a small hydropower plant (SHPP).
Private Capital
The construction of CGH Enxadrista was financed entirely with private equity — no public funds participate in the company's ownership structure. The financing was complemented by a bridge loan from BRDE, which has since been fully repaid.
Clean, Renewable Generation
As part of its operations, the company also pursues carbon credit certification, as all energy generated by CGH Enxadrista comes from a clean, renewable source.

Technical Data
Investments and Local Impact
The construction and operation of CGH Enxadrista have created — and continue to create — tangible development opportunities for the Covó community, in the rural area of Guarapuava. Key benefits include the substantial upgrade of the road serving the community — including the reconstruction of the bridge over the Rio das Mortes — along with local job creation and increased demand for regional services.
Notably, the connection of the plant's output to the Guará feeder, a distribution line owned by the regional utility, resolved long-standing issues with the quality and reliability of the electricity supply in the area.
Environmental Licensing
The licensing process for CGH Enxadrista began in 2008, with the first field surveys conducted by a multidisciplinary team of engineers, biologists, sociologists, geologists, and archaeologists.
Once the social and environmental impacts had been assessed and the environmental studies and programs approved by the Instituto Água e Terra (IAT) — the Paraná state environmental agency — construction began in 2019 and was completed in 2021, paving the way for commissioning tests and commercial operation.
Resilience: fourteen years between the idea and the first megawatt-hour.
Studies and design begin
First hydrological and topographic studies, and assessment of the technical feasibility of the Rio das Pedras river's hydropower potential.
Preliminary Environmental License
Preliminary License (LP) granted, confirming the environmental feasibility of the project.
Installation Environmental License
Installation License (LI) granted — technical clearance for civil works and electromechanical assembly to begin.
Construction begins
Site mobilization and start of the main civil works: dam, powerhouse, and headrace canal.
Construction completed
Civil works and electromechanical assembly concluded. Commissioning tests begin.
Power generation begins
Commercial operation authorized by ANEEL, the Brazilian electricity regulator. First megawatt-hour generated and fed into the Guará feeder.
Rio das Pedras — the Covó community
A small hydropower plant is, above all, an asset embedded in a watershed.
CGH Enxadrista is located on the Rio das Pedras river, in the rural community of Covó, municipality of Guarapuava, Paraná. A scale matched to the watershed, licensing conducted in dialogue with state and federal agencies, and a direct relationship with the local community have been structural elements of the project since 2008.
The energy generated is fed into the Guará feeder, a distribution line owned by the regional utility — a connection that resolved long-standing issues with the quality and reliability of the electricity supply in the area.
Full Regulatory Transparency
Operating a hydropower plant is, by its nature, a heavily regulated activity. We make publicly available the principal legal instruments, environmental studies, and monitoring reports for CGH Enxadrista.
A note for international readers: Brazilian environmental licensing follows a mandatory three-stage sequence — a Preliminary License (LP) attesting to the project's environmental feasibility, an Installation License (LI) authorizing construction, and an Operating License (LO) authorizing operation. Each stage is granted only upon compliance with the conditions of the previous one. All documents below are in Portuguese, as originally issued by or filed with the Brazilian authorities.
Partnerships that made the difference
From engineering to the bridge loan, CGH Enxadrista relied on exceptional partners, each specialized in infrastructure.
