Paraguay’s National Electricity Administration (ANDE) has launched a tender for the construction of the Loma Plata Photovoltaic Solar Power Plant, a 140 MW project located in the Boquerón department.

The facility will connect directly to Paraguay’s National Interconnected System (SIN) through the Loma Plata substation at 220 kV. The preliminary scope includes engineering design, construction, and the operation and maintenance of both the solar plant and its transmission infrastructure.

The state-owned utility said the hearing will be broadcast via Google Meet, with access to the session and the preliminary tender documents available on its institutional portal.

According to ANDE, the process began immediately after the enactment of the regulatory decree implementing Law No. 7599/2025. Under the decree, the utility submitted a request to Paraguay’s National Directorate of Public Procurement (DNCP) to hold the hearing and publish the preliminary specifications for the international tender.

The World Bank is supporting the project’s technical and financial development.

The initiative is part of Law No. 7599/2025, “On the Modernization of the Regime Regulating and Promoting Electric Power Generation from Non-Conventional, Non-Hydraulic Renewable Energy Sources.” The legislation replaces Law No. 6977/2023 and establishes a new framework for renewable energy development in Paraguay.

The law explicitly includes solar PV, wind, biomass, and geothermal technologies within the country’s non-conventional renewable energy regime. It also authorizes multiple participation models, including self-generation, cogeneration, commercial generation, and electricity exports.

A key provision for the solar sector appears in Article 24, which authorizes ANDE to launch international public tenders and sign renewable power purchase agreements with terms of up to 30 years.

The legislation also recognizes energy storage systems, allowing the competent authority to establish reference prices for renewable electricity “with or without storage systems.” The provision could pave the way for future tenders and contracting frameworks for hybrid solar-plus-storage projects, as well as remuneration mechanisms tied to firm capacity and hourly energy management.

Another notable aspect of the framework is the creation of a reference tariff for non-conventional renewable energy sources. The tariff is intended to compensate surplus electricity generated by grid-connected self-generators and co-generators, alongside a regulatory framework governing the metering, recording, and injection of electricity into the grid.

The implementation of Law No. 7599 through Decree 6034, together with the launch of the Loma Plata tender, marks the first concrete step under Paraguay’s new energy diversification strategy, in a power sector historically dominated by hydropower.

According to the International Renewable Energy Agency (IRENA), Paraguay had 8.8 GW of hydropower capacity and only 3 MW of operational installed solar power at the end of 2025.
