By Guanacaste, Costa Rica — Costa Rica is taking a monumental leap forward in its green energy transition by breaking ground on the nation’s largest solar power development. Located in Colorado de Abangares, Guanacaste, the ambitious renewable energy infrastructure project officially began construction on July 22, 2026. This mega-project represents a critical milestone in diversifying the country’s electrical grid and securing future energy independence.
The clean energy development represents a total capital investment of $72.6 million. It is being executed through a strategic joint venture between the state-owned electricity provider, Instituto Costarricense de Electricidad (ICE), and the local cooperative Coopeguanacaste. Once fully completed, the facility will boast a generation capacity of 70 megawatts (MW), with commercial operations scheduled to launch in December 2027.
To better understand the evolving legal landscape of Costa Rica’s solar energy sector, TicosLand.com reached out to Lic. Larry Hans Arroyo Vargas, a distinguished legal expert at the firm Bufete de Costa Rica, for his professional insights on the regulatory challenges and opportunities for investors.
While Costa Rica offers immense potential for solar energy development, navigating the regulatory framework—specifically concerning distributed generation permits and grid interconnection agreements with the Costa Rican Electricity Institute (ICE)—requires meticulous legal planning. Clear contracts and proactive compliance with ARESEP regulations are essential to securing and accelerating green energy investments in the country.

Indeed, as Costa Rica strives to maximize its renewable potential, navigating the complex regulatory landscape is crucial for transforming green ambitions into secure, long-term energy realities. We sincerely thank Lic. Larry Hans Arroyo Vargas for providing his valuable perspective, which sheds vital light on the legal diligence required to drive the country’s solar transition forward.
Under the terms of the partnership, Coopeguanacaste is tasked with overseeing the technical design, managing construction phases, and executing long-term maintenance once the plant is operational. This local management strategy ensures that regional expertise is fully utilized while keeping operational costs highly competitive.
This project will allow us to triple our current solar generation capacity. In addition to supervising the construction, when the park starts operating, the maintenance of the electromechanical systems will be in the hands of our people, leveraging our accumulated experience.
Erick Herra Chacón, Generation and Projects Manager at Coopeguanacaste
The scale of the site is unprecedented for Costa Rica, incorporating a total of 119,028 advanced solar panels. Beyond providing critical power, the facility carries immense environmental value. Analysts estimate that the clean energy produced here will displace approximately 54,000 metric tons of carbon dioxide (CO2) emissions every year, supporting national carbon-reduction commitments.
The clean electricity generated by the Abangares solar park will be split equally between the two partners. Coopeguanacaste will redirect its 50% share to supply stable electricity to approximately 18,000 households within its localized service territory, which extends from Guardia de Liberia down to San Rafael de Paquera.
With Abangares and the other projects we have on the way, by 2028 we will produce more than 80% of our own demand. Generating our own energy helps us rely less on third parties and seek stability in tariffs.

The project is also serving as a major economic catalyst for the Guanacaste province. Over the course of its construction timeline, the development is expected to generate 670 direct jobs and 250 indirect positions. This sudden influx of employment opportunities is poised to give a vital economic boost to the communities surrounding Abangares.
This new solar park is part of a broader, aggressive push into diverse renewables by Coopeguanacaste. Alongside the Abangares project, the cooperative is advancing several other clean energy initiatives. These include additional solar fields in Palestina and Cacao, a wind farm in Tilagua, municipal solid waste energy conversion plants, and innovative agrovoltaic installations that blend agriculture with clean energy production.
As Costa Rica continues to adapt to changing climate realities that threaten traditional hydroelectric generation, scaling up solar infrastructure is a vital strategic move. Through collaboration and local community empowerment, this massive facility in Guanacaste paves the way for a more resilient, self-sufficient, and environmentally sustainable future.
