Peru’s Andean BTS: Wind-Gravity Energy Storage Project

Brief Introduction: Providing Connectivity for the World’s Most Challenging Terrain

Deep in the Peruvian Andes, where rugged mountains rise more than 4,000 meters and remote villages cling to steep slopes, a quiet upgrade in energy and power technology is underway.Telecommunications companies are abandoning energy-wasting diesel generators in favor of a unique solution—wind and gravity energy storage—a so-called hybrid tailored for the region’s unique topographic and climatic conditions.

HighJoule has been at the forefront of onsite energy technology development, building a unique Base Station Storage System (BTS) for standalone telecom base stations/towers that is more rugged than ever before. Our hybrid wind power system performs well in Peru’s challenging high altitude environment and offers the following benefits:

• Guaranteed 24/7 power supply for off-grid sites
• Low lifecycle costs, 40-60% lower than diesel alternatives
• Minimal environmental impact on sensitive mountain habitats
• Aligned with Peru’s ambitious renewable energy goals

Andean Energy Challenge: Why old solutions won’t work

Harsh conditions require innovative solutions

Peruvian mountains offer some of the world’s most challenging conditions for telecom power systems:

• Altitude: Each base station is over 3500 meters above sea level, with air density reduced by 30%
• Temperature fluctuations: Daily temperature fluctuations of up to -15°C to 25°C challenge traditional batteries
• Limited access: Some sites require helicopter or human transport equipment
• Earthquakes: Frequent earthquakes require robust structural solutions

Expensive diesel dependency

In such situations, the setup of traditional diesel generators is severely constrained:

1. Logistical challenges: Fuel transportation to remote locations can cost more than $50,000
2. Frequent breakdowns: Cold starts and low air pressure can reduce generator life by 40-60%
3. Environmental risks: Leaks in sensitive watersheds carry high fines
4. Carbon liability: Peru’s new carbon tax will impose 15-20% on operating costs

Wind energy: Taking advantage of the Andes’ rich resources

Why wind power dominates high-altitude applications

Peru’s mountainous regions have abundant wind resources, especially in:

• Southern regions (Arequipa, Puno), with sustained wind speeds of 8-12 m/s
• Mountain passes, where wind speeds naturally increase
• Coastal highlands (Ica, Ancash), with abundant afternoon breezes

Our BTS-Wind system takes full advantage of these resources

• Reliable, compact transport turbines (10-20kW)
• Cold packs with blade heating and special lubricants
• Cyclone-resistant design to withstand gusts of up to 60 m/s
• Smart yaw function to maintain optimal position in a variety of mountain wind conditions

Technology innovations for mountain deployment

• Modular towers that can be erected without cranes
• Self-supporting layouts that minimize on-site workspace
• Anti-icing coatings to prevent blades from icing
• Generators that can operate at low speeds even in thin air

Gravity energy storage: the perfect mountain complement

Breaking the intermittency of wind power with a simple mechanical design

While wind power is amazing, energy storage remains a challenge. Gravity storage is superior to battery storage in many ways:

• Service life of more than 30 years, compared to 5-8 years for lithium-ion batteries
• No degradation in low temperatures
• Contains no toxic materials that could pollute watersheds
• Increases capacity using local weights (stones, concrete)

How our Mountain GSM (Gravity Storage Module) works

1. Charging cycle: 5-10 tons of weight is lifted vertically by surplus wind power
2. Storage phase: Weight is suspended in a stable frame
3. Discharge: At low wind speeds, controlled drop drives generator
4. Precise control: Advanced algorithms regulate output to base station (BTS) load demand

Key technologies for Andean applications include:

• Anti-seismic shock absorbers to keep weights stable
• Modules can be transported by helicopter or small vehicle
• Dry lubrication system to prevent ice formation at high altitudes

Wind-Gravity Integrated Applications

Highest Reliability System Design

Our complete wind gravity site energy solution includes:

1. Power generation: 10-20kW wind turbine array
2. Energy storage: 24-72 hours of gravity energy storage capacity
3. Power management: Hybrid advanced controller
4. Monitoring: Satellite connection performance monitoring

Case study: Arequipa highlands deployment

The new wind power system at 4,200 meters above sea level has proven its success:

• Location: 70 km from the nearest grid
• Configuration: 2×10kW wind turbines + 48 hours of gravity energy storage
• Results:
1. Availability of 99.2% (previous diesel system had an availability of only 82%)
2. Annual operating costs reduced by 65%
3. 15 tons of CO2 emissions reduced per year
4. Payback period of less than 4 years

Economic advantages of renewable energy BTS power

Economic advantages over diesel

• More capital savings: wind-gravity systems are currently 20-30% cheaper than comparable diesel systems
• Lower operating costs: no fuel costs, minimal maintenance costs
• Tax advantages: Peru’s renewable energy incentives recover 30% of project costs
• Future-proof: protected from rising fuel prices and carbon taxes

Peru Policy Advantages

• 15-year tax exemption under the Renewable Energy Law (Legislative Decree No. 1002)
• Rural Electrification Fund, up to 40% for off-grid projects
• Accelerated depreciation of renewable energy assets

Implementation: From Assessment to Operation

Our Tested Deployment Approach

1. Site Assessment: 3-6 months of wind and terrain surveys
2. System Design: Modifications based on altitude, wind direction and load profiles
3. Transport Planning: Knowledge of mountain transport logistics
4. Installation: Local workforce training and phased commissioning

Andes Deployment Lessons Learned

• Prefabricated foundations reduce field work to 60%
• Community involvement ensures long-term security and maintenance
• Hybrid controllers must prioritize telecom load generation during low-load periods

Future Outlook: Expansion in the Andes

• AI-optimized energy management to predict wind patterns
• Community microgrids that share base station (BTS) power infrastructure
• Modular design for rapid deployment in the Andes

Conclusion: A new paradigm for mountain telecom

Wind power combined with gravity energy storage offers a revolutionary solution for remote base station sites in Peru, with benefits including:

• Unparalleled reliability in harsh environments
• More economical than diesel alternatives
• Environmental sustainability in line with Peru’s green agenda
