Step-by-step guide to carry out a Distributed Renewable Generation project according to Guatemala’s NTGDR Technical Standard.

Introduction to NTGDR

The Technical Standard for Distributed Renewable Generation and Self-Producing Users with Energy Surplus (NTGDR) establishes the regulatory framework for the development of distributed generation projects in Guatemala.

This guide details the 5 essential steps that every developer must follow to successfully implement a Distributed Renewable Generation (GDR) project in the country.

Application and Authorization Process

1. Submission of Capacity and Connection Assessment Request

The interested party submits the Capacity and Connection Assessment request to the Distributor.

• General project information (name, location, contact)
• Cartographic map and project coordinates
• Technical data (energy source, capacity, single-line diagram)
• Electrical parameters and connection line plans
• Quota record (if a hydroelectric project)
• Environmental resolution or proof of environmental authorization process

2. Evaluation by the Distributor

The Distributor reviews the request and prepares the necessary studies.

• Request review (5 days to request clarifications)
• Interested party response (5 days)
• Copy sent to CNEE
• Electrical studies preparation (maximum 45 days)
• Assessment includes: capacity analysis, loss evaluation, modification costs

3. Review and Authorization by CNEE

The CNEE reviews the Assessment and issues the authorization resolution.

• Assessment review (30 days)
• Request for additional information if necessary
• Issuance of connection authorization resolution

4. Construction and Equipment Installation

The interested party builds the necessary infrastructure under supervision.

• Construction of connection line and equipment (costs borne by the interested party)
• Installation of protection and disconnection systems
• Inclusion of inverters if not producing alternating current
• Distributor supervision for technical standards compliance

5. Testing and Connection

Execution of tests and coordination for final connection.

• Facility operation tests
• Technical report delivery to the Distributor
• Connection date agreement
• Supervised and coordinated connection with the Distributor

Operation and Maintenance

Operation and Control

The GDR operates complying with quality standards with automatic disconnection in case of failures.

Energy Commercialization

Sale to Distributors, Wholesale Market, or surplus accreditation in billing.

Maintenance and Inspections

Responsibility of the GDR with inspections by the Distributor and CNEE.

Disconnection

For maintenance, failures, or non-compliance, coordinated with the Distributor.

Penalties and Validity

Oversight by CNEE with penalties according to the General Electricity Law.

Commercialization Options

The GDR can sell its energy to:

• Distributors: through direct contracts
• Wholesale Market: under AMM rules
• Surpluses: accredited as balance in electricity billing

Key Aspects to Consider

Key Deadlines

• Distributor clarifications: 5 days
• Interested party response: 5 days
• Electrical studies: maximum 45 days
• CNEE review: 30 days

Responsibilities

• Construction costs: borne by the interested party
• Maintenance: GDR responsibility
• Supervision: Distributor and CNEE
• Oversight: CNEE

Conclusions

The implementation of a Distributed Renewable Generation project in Guatemala requires following a structured process and complying with multiple technical and regulatory requirements. Project success depends on careful planning and strict compliance with the NTGDR.

It is essential to have specialized advisory services to navigate this process efficiently and ensure compliance with all current regulations.
