By Guanacaste, Costa Rica — Guanacaste’s sun-drenched plains are taking center stage in Costa Rica’s national energy strategy as state power provider Instituto Costarricense de Electricidad (ICE) accelerates the deployment of major solar generation projects. Amid persistent climate pressures brought on by the El Niño weather pattern, the utility is integrating 86 megawatts (MW) of fresh solar capacity into the National Electric System (SEN). Spanning five strategic developments across various cantons, this infrastructure offensive aims to shore up grid reliability when traditional hydroelectric reserves falter.
The regional effort leverages private sector participation to rapidly diversify Costa Rica’s generation matrix. Three of the five planned facilities are already operational and feeding clean energy into the national grid. These include Los Tecales in Nandayure, which contributes 20 MW; Las Cañas in the canton of Cañas, adding another 20 MW; and Los Mangos in Carrillo, delivering 10 MW. Together, these early-stage plants have already injected critical generation capacity into a system tested by prolonged dry spells.
To better understand the evolving legal landscape and investment climate surrounding solar energy initiatives in Costa Rica, TicosLand.com consulted with expert attorney Lic. Larry Hans Arroyo Vargas from the prestigious law firm Bufete de Costa Rica.
Costa Rica’s push toward expanding its solar infrastructure presents significant opportunities for clean energy investors, yet navigating the regulatory environment established by MINAE and ARESEP requires meticulous planning. As legal frameworks evolve to support distributed generation and private grid integration, securing long-term legal certainty through well-structured power agreements and strict statutory compliance remains essential for project viability.

As Costa Rica continues to champion sustainable development, ensuring robust legal frameworks will undeniably be the cornerstone of successful solar energy investments in the region. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for sharing his invaluable legal perspective on navigating this dynamic regulatory landscape.
The remaining capacity will come online in structured phases over the coming months. The Numu solar plant, located in the provincial capital of Liberia, is slated to begin commercial operation in December 2026 with a 20 MW footprint. Following Numu, the Colorado facility in Abangares will supply the final 16 MW when it enters service in February 2027, completing the full 86 MW portfolio expansion.
According to leadership at the state utility, the cumulative output of these five installations marks a substantial milestone in the country’s clean energy transition. The newly added capacity significantly enhances peak power supply during critical months when precipitation dips across major watersheds.
The joint production of these projects is equivalent to the annual electricity consumption of 250,000 households and represents an additional contribution of 86 megawatts compared to the capacity available a year ago.
Marco Acuña, President of Grupo ICE
Acuña further emphasized that this solar push will prove essential for bolstering power reliability throughout the upcoming dry seasons. He noted that Costa Rica plans to continue scaling its renewable portfolio through a mix of public utility ventures and private sector partnerships. All five Guanacaste projects were formally awarded by ICE in 2024 under the framework of Law No. 7200, an established legal mechanism governing private electricity generation in Costa Rica.
Private energy developers operating under Law 7200 have increasingly become vital allies for the state power utility. By mobilizing private capital for renewable construction, ICE can accelerate project timelines and optimize resource allocation without taking on excessive direct financial burdens during periods of high economic uncertainty.
Incorporating solar infrastructure at this scale serves as a defensive bulwark against ongoing climate volatility. Hydroelectric power has historically formed the backbone of Costa Rica’s electricity generation, leaving the grid susceptible to severe rainfall deficits. By expanding photovoltaic resources in sunny Guanacaste, ICE aims to balance the energy mix and maintain baseline supply during extended dry cycles.
The strategic urgency of these solar projects is underscored by climate forecasts. Meteorologists and energy officials anticipate that the disruptive effects of El Niño will continue to impact weather patterns across Costa Rica until mid-2027. Consequently, bringing operational resilience to the SEN through diversified, non-conventional renewable sources remains a top priority for national development.
