Chile continues to solidify its position as a leader in clean energy with the approval of a new renewable energy transmission line project developed by Grupo Saesa. This development, which recently received the green light from environmental authorities, carries an estimated cost of USD 80 million (EUR 75 million) and marks another crucial step in the nation’s energy transition.
Project Details and Cost for Chile renewable energy
Chile’s Environmental Assessment Service (SEA) has officially approved the Environmental Impact Statement (EIS) for a significant new transmission project. Developed by Grupo Saesa, the project involves the construction and operation of the 220 kV Itahue – Los Maitenes double-circuit transmission line and its associated substations. The total investment is estimated at USD 80 million (EUR 75 million).
Spanning approximately 108 kilometres (67 miles), the transmission line will traverse the communes of Linares, LongavÃ, Retiro, Parral, and Cauquenes within the Maule region. Grupo Saesa highlighted that the project was secured through a competitive International Public Tender, underscoring its strategic importance.
Boosting Chile renewable energy Integration
The Itahue – Los Maitenes line is a vital component of Chile’s National Electric System. Once operational, it will dramatically improve the grid’s capacity to integrate and transmit power from renewable sources. This is particularly crucial for the Maule region, a hub for developing renewable energy projects, ensuring that the clean energy generated there can be efficiently delivered to population centers.
This project is part of a larger national strategy to overcome grid congestion. It complements other flagship projects like the recently approved Kimal–Lo Aguirre high-voltage line. This major undertaking is designed to transport vast amounts of solar power from the sun-drenched Atacama Desert in the north to central demand hubs, including Santiago, helping to reduce energy curtailment and stabilize the grid.
Chile’s Commitment to renewable energy
Chile has long been recognized as a global frontrunner in renewable energy, leveraging its immense natural resources like solar irradiation and powerful winds. As detailed in the Global Solar Report, the country’s progress sets a high bar. While neighbors like Peru are also expanding their solar capacity, Chile’s proactive infrastructure development is key to its leadership. The Itahue – Los Maitenes line is a perfect example of the broader effort to build out this infrastructure and decrease reliance on fossil fuels.
These projects align with Chile’s ambitious goal of generating 70% of its electricity from renewable sources by 2030. The government is also demonstrating a commitment to streamlining approvals, with the Kimal–Lo Aguirre project receiving its environmental permit in under 12 months—a remarkably fast timeline. This reflects a coordinated push to accelerate decarbonization by supporting the entire renewable energy value chain, from the solar panel raw materials to the final transmission infrastructure.
Job Creation and Economic Impact of Chile renewable energy
Beyond the clear environmental advantages, the Itahue – Los Maitenes project is poised to deliver significant economic benefits to the Maule region. The construction and ongoing operation of the transmission line will generate local employment and stimulate economic activity. Grupo Saesa has reiterated its commitment to collaborating with local communities to ensure the project’s positive impact is widely felt.
On a national scale, these large-scale infrastructure investments are expected to lower long-term energy costs for consumers and industries. By enabling more efficient use of the country’s cheapest energy sources—solar and wind—projects like this and the Kimal–Lo Aguirre line contribute to a more resilient and affordable energy supply for all.
Chile’s Renewable Energy Future
The approval of the Itahue – Los Maitenes transmission line is a powerful testament to Chile’s unwavering commitment to a sustainable energy future. As the country continues to invest in generation projects and the critical transmission infrastructure needed to support them, it is well-positioned to not only meet but exceed its climate goals.
The integration of renewables into the national grid is fundamental to Chile’s energy security and environmental stewardship. This new transmission line will play a critical role in ensuring the country can meet its growing energy demands while simultaneously reducing its carbon footprint. Chile’s proactive approach serves as a compelling model for other nations navigating the transition to a cleaner, more sustainable energy system.
