Hydropower Water Concessions through the Water Directorate
Geo Costa Rica conducts preliminary assessments of water resources and the environmental and territorial constraints of hydropower projects, and manages hydropower concession applications before Costa Rica's MINAE Water Directorate.
Our approach is to establish first whether streamflow, hydraulic head and site conditions justify proceeding to further studies, environmental assessment and specialized engineering.
I have a river with an elevation drop on my property. Can I generate electricity?
Water and elevation difference are a promising starting point, but do not by themselves demonstrate that a hydropower project is feasible. The first step is to determine how much resource can be used and what site constraints exist.
Is there enough streamflow?
We assess available information about the river, observed flows, seasonal behavior and the need for further characterization.
Is there usable hydraulic head?
Topography and elevation differences between parts of the site allow a preliminary appraisal of its energy potential.
Does the site merit further investment?
We combine water resources, topography, environmental factors, accessibility and restrictions to inform an early decision.
What is a Hydropower Water Concession?
A hydropower water concession is the instrument through which MINAE authorizes the use of the potential and kinetic energy of public-domain waters for purposes established under applicable regulations.
Water
The project harnesses the energy associated with water movement and differences in elevation.
Hydraulic power
The Water Directorate has specific procedures for electricity generation and other mechanical uses of hydraulic power.
Water Directorate
Geo Costa Rica manages and technically coordinates the process. The competent MINAE authority decides whether to grant the concession.
Deciding whether to proceed is not the same as applying for a concession
Geo Costa Rica can first conduct a preliminary assessment of the water resource and site to determine whether there is a sufficient basis for more detailed studies, permits and designs.
Preliminary Assessment
Seeks to establish whether streamflow, hydraulic head and general site conditions justify further project development.
- Source and background information
- Available flow data or existing information
- Preliminary hydraulic head
- Topography
- Accessibility
- Environmental constraints
- Territorial restrictions
- Initial regulatory pathway
Hydropower Water Concession
Once a project moves forward, the formal application requires substantially more developed technical and environmental information and is processed through the Water Directorate.
- Project information
- Supporting water resource data
- Environmental studies
- Design information
- Territorial documentation
- Institutional procedures
Streamflow and hydraulic head are essential, but do not determine overall feasibility
Preliminary hydraulic potential depends primarily on how much water can be used and the available elevation difference. However, the decision to proceed also depends on the territory and project restrictions.
Streamflow
How much water is available, and how does it vary throughout the year?
Hydraulic head
What elevation difference could be harnessed?
Constraints
Which environmental, territorial or access restrictions affect the initial concept?
Preliminary Assessment of Water Resources and Site Conditions
Geo Costa Rica can integrate available river and terrain information into an initial assessment to help decide whether the project merits further studies and investment.
The assessment does not certify feasibility or guarantee generation capacity.
Its purpose is to reduce uncertainty and help the owner or investor decide whether to develop the project further before commissioning higher-cost specialist engineering.
Measuring flow helps establish the water resource actually available
River flow can vary considerably between dry, transitional and rainy seasons. A single observation therefore may not adequately represent the conditions relevant to water use.
River Flow Gauging
Measures flow under specific conditions and provides direct data on the water source.
View River and Spring Flow GaugingAssess less favorable conditions
When technically relevant, dry-season measurements help prevent a rainy-season observation from creating overly optimistic expectations about the resource.
A Hydrological Study helps explain resource variability
As the project advances, hydrology relates observed flows to watershed conditions, temporal variability and factors relevant to water use.
Watershed
Understand the system feeding the stream.
Variability
Analyze how water availability changes over time.
Streamflow
Provide technical support for water availability.
Map of constraints on hydropower development
Geo Costa Rica can integrate hydrological, topographic, environmental and territorial information to identify the site's main opportunities and constraints.
Features that can be included
- Property boundary
- River and drainage network
- Topography and elevations
- Preliminary hydraulic head
- Roads and access
- Protected buffer areas
- Land cover and environmental constraints
- Natural hazards
- Existing infrastructure
Conceptual, not detailed engineering
Preliminary identification of areas of interest helps evaluate alternatives but does not constitute final hydraulic infrastructure design.
A site with attractive hydraulic characteristics may face significant environmental or territorial constraints
Before advancing the design, it is advisable to identify restrictions that may affect location, costs, scope or even whether the project should proceed.
From river potential to a technically developed project
Source
Identify the water resource and its background information.
Streamflow + head
Conduct a preliminary assessment of hydraulic potential.
Constraints
Review territory, environment and accessibility.
Decision
Determine whether further development is advisable.
Studies
Prepare or coordinate more detailed information.
SETENA
Undertake the applicable environmental assessment.
Concession
Apply for water use authorization through the Water Directorate.
Engineering
Specialists develop the required detailed design.
Project
Proceed toward the other necessary authorizations and implementation.
Environmental assessment and the hydropower concession are part of the project's regulatory pathway
Environmental Assessment
For hydroelectric generation, assessment before SETENA is part of the regulatory requirements associated with a hydropower concession application.
The applicable environmental instrument and scope must be established according to the project and regulations.

Applies to the use of the resource's potential and kinetic energy under the specific hydraulic power concession regime.
A hydropower project may require additional authorizations
Intakes, return flows, structures and other project interventions can trigger additional requirements depending on their location and design.
Works in Watercourses
Where proposed works physically intervene in a public-domain watercourse, the corresponding procedure must also be assessed.

Hydraulic power and hydropower potential in Costa Rica
What is a Hydropower Water Concession?
It is the MINAE authorization to harness the potential and kinetic energy of water under the applicable hydraulic power regulatory framework.
Who handles hydropower water concession applications in Costa Rica?
Applications are submitted to the MINAE Water Directorate. Geo Costa Rica can prepare and coordinate the technical, environmental and administrative components.
Does Geo Costa Rica manage hydropower water concessions?
Yes. Geo Costa Rica can initially assess the water resource and site, coordinate the necessary studies and manage the hydropower concession application before the Water Directorate.
I have a river with an elevation drop on my property. Can I generate electricity?
There may be potential, but flow, head, resource variability, territorial, environmental and regulatory conditions must be evaluated before deciding to proceed.
How can I find out whether my property has hydropower potential?
Geo Costa Rica can combine flow, head, topography, mapping and environmental constraints in a preliminary assessment to help decide whether further studies are worthwhile.
What is needed to determine whether a river could generate electricity?
At a minimum, the usable streamflow, available head and site constraints must be understood. More detailed studies are required as the project advances.
Are flow and head enough to know whether a project is feasible?
No. They are essential for estimating hydraulic potential, but environmental conditions, territory, accessibility, necessary works, regulations and development costs must also be considered.
Can Geo Costa Rica calculate how much electricity the project would generate?
Geo Costa Rica can prepare a preliminary hydraulic estimate to inform an early decision. It is not a definitive energy design and does not guarantee future output.
Does Geo Costa Rica design turbines or generators?
That is not Geo Costa Rica's primary service. As the project progresses, specialized professionals should develop these components, coordinated as part of the project team where appropriate.
Should I commission all the detailed designs first?
It is generally better to reduce major uncertainties first. A preliminary assessment can show whether there is enough justification for subsequent investment in detailed engineering.
Do I need to measure river flow?
Flow information is fundamental to resource assessment. The need and scope of flow gauging depend on existing records and the project stage.
Is it advisable to measure the river in the dry season?
This can be especially useful because it reveals less favorable conditions and reduces the risk of evaluating the resource only during periods of abundant water.
Do I need a Hydrological Study?
Its need and scope depend on the project stage and characteristics. A developed concession application requires stronger hydrological evidence than an initial preliminary assessment.
Do I need SETENA approval for a hydropower project?
For hydroelectric generation, environmental assessment through SETENA is part of the concession-related regulatory pathway. The appropriate environmental instrument depends on the project.
Can Geo Costa Rica also handle SETENA procedures?
Yes. Geo Costa Rica can coordinate environmental assessment and the geoenvironmental studies needed for the project's SETENA procedures.
Can Geo Costa Rica coordinate engineering professionals after the preliminary assessment?
Yes. When further development is justified, Geo Costa Rica can coordinate the transition to civil, hydraulic, mechanical, electrical, structural or electromechanical engineering specialists, as required.
What if the preliminary assessment suggests the project is not promising?
That finding is valuable too. Early identification of insufficient resources, severe constraints or likely disproportionate costs can prevent much larger investments in designs and permits.
