Korkia, a Finnish renewable energy investor, and its Chilean development partner, Solar Ray, have received environmental certification for a 150/750 MWh BESS project in Chile. The Paicavi BESS was approved by the regional environmental permit authority. The project is close to an existing substation and is intended to draw and store excess electricity before feeding it back into the grid. Paicavi BESS operations are anticipated to start in September 2028 and terminate in November 2058. Also, the alliance is working on solar and storage projects, as well as stand-alone BESS projects in Chile. This plan will also feature the installation of 150 containerized 5MWh battery units and a 33/110kV step-up substation to connect to the national grid. It also combines 280 MW of utility-scale solar PV with a 1.24 GWh BESS. These developments depend on robust hardware such as cable suspension clamps.
Cable suspension clamps provide the safety, dependability, and lifespan of the electrical infrastructure. The cable clamps serve as mechanical support for electricity cables, electrical protection, and grid integration. Suspension clamps provide mechanical support for power lines connecting battery storage units, inverters, and transformers. They support the weight of the conductors, preventing excessive drooping and short circuits. Wind, seismic activity, and operational forces all generate vibrations, which suspension clamps absorb and dissipate. Cable suspension clamps use insulated bushings to provide electrical separation. They ensure a safe gap between conductive and structural components. This protects against inadvertent contact, ground faults, and flashovers.
Quality assurance of cable suspension clamps used in Chile’s BESS projects
Cable suspension clamps secure and support hefty power cables, assisting with thermal and mechanical loads. The quality assurance program for cable suspension clamps consists of specification and design review, supplier qualification, inspection, testing, traceability, installation quality assurance, and maintenance protocols. Without quality assurance, suspension clamps may fail due to material non-conformance, welding, corrosion failure, dimensional non-conformance, thread defects, or incorrect clamp selection. During installation, quality assurance comprises using the correct clamp type per design, applying the proper tension to bolts, doing alignment checks, verifying cable seating, and providing documentation with images. TTF-certified cable suspension clamps ensure mechanical integrity, operational reliability, and regulatory compliance for Chile’s high-value BESS infrastructure.
Cable suspension clamps play crucial roles in Chile’s BESS project installation
Cable suspension clamps ensure that BESS facilities’ cabling is safe, reliable, and orderly. They ensure that the BESS system performs structurally, operationally, and safely. The cable suspension clamps play the following tasks in the Chilean BESS project installation.
- Supporting cable weight—cable suspension clamps bear the weight of power, control, and communication cables. They prevent sagging, maintain alignment, and reduce stress on cable insulation and termination points.
- Maintaining proper alignment—the clamps ensure that cables remain routed along trays, racks, or overhead supports. They also ensure the cables remain spaced to avoid mechanical interference. They also ensure the cables remain at the necessary clearance from equipment, walls, or grounding structures.
- Reducing mechanical stress—suspension clamps help distribute mechanical loads and mitigate stresses caused by cable tension. The clamps reduce the risk of insulation damage, fatigue, and cable failure.
- Ensuring electrical safety— suspension clamps hold cables to prevent unintended contact with grounded structures, reduce the risk of abrasion, insulation wear, and short circuits. They also maintain proper separation between high-voltage and low-voltage cables.
Market and system implications of Chile’s BESS project development
The development of battery energy storage systems in Chile has a disruptive impact on both energy markets and the operational power system. BESS increases renewable penetration, minimizes curtailment, and lowers volatility. These impacts include:
- Enhanced grid flexibility and renewable integration—BESS projects enable energy time-shifting by storing excess generation during low-demand periods. They reduce renewable curtailment and increase the economic value of PV and wind projects.
- Price volatility mitigation—large-scale storage mitigates short-term price spikes by injecting stored energy when spot market prices are high and absorbing excess generation when prices are negative.
- Improved grid reliability and resilience—BESS projects strengthen system reliability by providing dispatch to balance load and generation. They also maintain continuity during transmission congestion or line outages.
- Delay of transmission and distribution investment—BESS can reduce load on existing substations and reduce congestion costs. This results in economic and environmental benefits in regions with constrained grid infrastructure.
