ADSS and OPGW cables boost Colombia’s green grid shift

Wind and Solar energy expansion

IRENA, the International Renewable Energy Agency, identifies vast investment opportunities for utility-scale solar and onshore wind energy projects in Colombia. The country has significant land potential suitable for both solar PV and onshore wind development. Colombia is unveiling a 1,600 GW renewable energy potential. The country also added 1.6 GW of new utility-scale in 2024, and wind remains at 19 MW installed in La Guajira and the Caribbean coast. This demands grid upgrades to support the increased energy production. The key transmission lines include the La Guajira’s 500 kV. There is also the integration of storage solutions to manage intermittency and align with Colombia’s electric demand peaks. Increased generation capacity could lower end-user prices in remote areas. Colombia can also export solar and wind power to countries like Panama, Ecuador, and Central America. ADSS/OPGW cables enable reliable communication, monitoring, and control of renewable energy systems.

ADSS (All-Dielectric Self-Supporting) and OPGW (Optical Ground Wire) cables contain fiber optics that send real-time data from solar farms and wind turbines to control centers. They support SCADA systems to allow operators to track performance, detect faults, and optimize energy production. OPGW is installed on transmission lines, acting as a ground wire for lightning protection, and provides fiber optic communication for grid management. ADSS serves in distribution networks where no metallic reinforcement is necessary to avoid electrical interference. Fiber optics in the cables enable wind turbine condition monitoring, solar plant performance tracking, and reduced downtime. ADSS and OPGW cables are crucial for efficient, reliable, and smart renewable energy projects in Colombia. They ensure secure data transmission, grid stability, and remote management for solar and wind power plants.

ADSS and OPGW cables in solar and wind farms in Colombia

ADSS and OPGW cables ensure the success and efficiency of solar and wind energy projects in Colombia. The cables are crucial for grid communication, control, monitoring, and safety in remote areas. For instance, where wind farms connect to 500 kV transmission systems, OPGW serves as both a grounding conductor and the fiber-optic backbone for communication between turbines, substations, and national grid operators. ADSS cables carry fiber-optic data between inverters, transformers, and substations. The cables ensure smart grid functionality, fast fault response, and grid stability. ADSS and OPGW cables support renewable energy auctions to allow developers to meet interconnection requirements with proper data and control systems. Here are the roles of ADSS and OPGW cables in solar and wind farm infrastructure.

ADSS and OPGW cables support utility poles
  • Data transmission—ADSS cables enable real-time SCADA communication for solar fields and wind farms. This is crucial where high electromagnetic interference would impact metallic cables.
  • Cost-effective deployment—ADSS cables can be easily strung between poles to reduce infrastructure and labor costs in rural areas.
  • Environmental resistance—the cables are able to withstand UV, high winds, and temperature changes. ADSS cables perform well in harsh climates in Colombia and Caribbean solar zones.
  • Grid protection and monitoring—OPGW carries critical data for protection relays, fault detection, and grid synchronization. They are essential for integrating large-scale wind and solar energy into the national grid.
  • Backbone connectivity—OPGW cables connect wind farms to central dispatch centers and ensure reliable coordination and real-time load balancing.
  • Lightning protection—OPGW also protects renewable installations from lightning in Colombia, which is prone to storms.

Impacts of increased solar and wind capacity in Colombia’s energy sector

The increased solar and wind capacity in Colombia is reshaping the country’s energy sector, economy, environment, and geopolitical positioning. IRENA identified up to 1,600 GW in untapped renewable potential, which is restructuring its energy economy, improving life, and protecting natural ecosystems. The impacts include:

  1. Energy security and grid resilience—solar and wind provide complementary generation profiles during dry seasons, strengthening the grid’s resilience. It expands energy access to rural communities, reduces transmission losses, and creates localized energy hubs.
  2. Lower electricity costs and market diversification—solar and wind availability drive down wholesale electricity prices, which benefits both consumers and industries. It also helps diversify the market to reduce exposure to fossil fuel and hydro price volatility.
  3. Economic development and job creation—renewables stimulate growth in solar panel installations, turbine assembly, maintenance, and energy storage. Increased capacity generates green jobs in rural areas. It also drives economic decentralization and boosts regional development in marginalized areas.
  4. Environmental protection and climate goals—increasing Colombia’s solar and wind share displaces energy from coal, diesel, and natural gas. It helps cut emissions and improves air quality.
