Costa Rica's 2026 Water & Solar Power Surge: Top Sectors & Winning Tenders

Costa Rica, a beacon of sustainability in Central America, is currently experiencing an unprecedented surge in its renewable energy and water infrastructure sectors. For bid managers, export managers, procurement officers, and project developers worldwide, 2026 presents a golden opportunity to engage with a nation committed to green growth. The Instituto Costarricense de Electricidad (ICE), alongside significant funding from the Inter-American Development Bank (IDB), is orchestrating a transformative period, pouring hundreds of millions into projects that promise not only environmental stewardship but also lucrative tender opportunities. This isn't just about building infrastructure; it's about investing in a greener future, and savvy businesses are already positioning themselves to participate.

The numbers tell a compelling story. Costa Rica aims to add a substantial 412 MW of new generation capacity, a mix of 270 MW solar, 122 MW wind, and 20 MW biomass, backed by an estimated investment of $539 million. Simultaneously, the nation is advancing major hydroelectric initiatives, including a significant $245 million hydro project. These figures from 2026 highlight a vibrant procurement landscape characterized by transparency, digitized tendering, and a clear preference for private-sector involvement through Build-Own-Operate (BOO) and Build-Operate-Transfer (BOT) models. For those looking to tap into this dynamic market, understanding the key sectors and procurement mechanisms is paramount. And this is precisely where a powerful tool like TendersGo becomes indispensable, offering a window into these opportunities, whether you're searching for specific Costa Rica water tenders or focusing on the burgeoning Costa Rica solar projects .

Unpacking Costa Rica's Green Goldmine: Top Sectors in 2026

When we look at where Costa Rica is directing its investment, two sectors stand out: renewable energy and water infrastructure. The country's commitment to these areas is not just aspirational; it's backed by concrete projects and substantial budgets. For instance, the renewable energy sector, encompassing solar and wind, is seeing the highest activity, with $539 million allocated specifically for 2024–2026 projects. This includes a target of 412 MW of new capacity, with 270 MW dedicated to solar and 122 MW to wind. Under Laws 7200 and Decree 37124, ICE is actively engaging the private sector through BOO models for projects up to 20 MW and BOT models for those between 20–50 MW. This strategic approach ensures a diverse and competitive market for energy developers.

Recent awards confirm this trend. In 2024–2025, a 166 MW package was awarded, comprising five solar and four wind projects primarily in Guanacaste Province. Companies like Numu, Cover Energy Los Tecales, and Solar Generation South Colorado secured significant solar contracts, while ESPH is making strides with the 122 MW El Quijote wind project. Looking ahead, a 100 MW solar tender for Puntarenas Province, with a deadline in October 2025, promises to supply 65,000 households. These are not just isolated contracts; they are part of a broader, well-funded national strategy. To stay ahead of these opportunities, a platform like TendersGo, with its real-time tender updates and comprehensive coverage of 220+ countries, is an absolute necessity. You can easily set up unlimited email alerts for "Costa Rica solar" or "Guanacaste wind" to ensure you never miss a beat.

Beyond energy, the water and hydroelectric infrastructure sector is also a hotbed of activity. A major $245 million hydro project, focused on grid expansion and renewable integration, began procurement in 2025/2026. This isn't the only venture; future hydro projects like the 50 MW Fourth Cliff Hydro, expected to be operational by 2030, and the 135 MW Borinquen I & II Geothermal projects, coming online in 2027 and 2032, illustrate a sustained commitment to water resource management and clean energy generation. The IDB's significant funding for sanitation and water supply under the "Second Renewable Energy, Transmission, and Distribution Program" further underscores the sector's importance. Finding these specialized tenders often requires advanced search capabilities. TendersGo offers sophisticated filtering options, allowing you to search by CPV/NAICS/UNSPSC classification codes relevant to water treatment, hydroelectric power, or environmental engineering, ensuring you pinpoint the exact opportunities that match your expertise. Take a moment to explore how advanced search and filtering can transform your procurement strategy.
