6. Sustainable Energy and Mobility
Santa Teresa National Park is steadily advancing toward a sustainable management model, incorporating technologies that promote responsible energy use and electric mobility.
Electric Mobility: SAVE Charging Systems
On January 20, 2023, two new Electric Vehicle Supply Equipment (SAVE) units were installed, complementing the existing one and strengthening the charging network in the eastern region.
The SAVE system operates between the electrical grid and the vehicle, managing the charging process with a strong focus on user safety.
Before enabling power flow, the system verifies the presence of the vehicle and the conditions required for a safe connection.
Benefits of the SAVE system:
- Enhanced safety
- Reduced charging time
- Optimized energy use
- User identification
- Measurement of energy consumption
Since December 2018, the Park has been part of the southern electric mobility corridor (Colonia del Sacramento – Chuy), following the installation of a SAVE unit by UTE, with a second unit added in 2023.
Although some smaller vehicles can be connected to conventional outlets (Schuko), the use of SAVE systems is recommended due to their advanced management and safety features. These systems are available in portable, residential and high-capacity formats, including pedestal and wallbox configurations.

Energy Efficiency Project
Since 2017, the Army Parks Service (SEPAE) has been working with EFICENER–UTE on an ambitious energy efficiency project. Initial technical assessments evaluated 20 electrical supply points, identifying the five most relevant for improvement.
The Park’s water system was also analyzed, considering its 20 km extension and the potential to optimize potable water production and distribution.
Audit and ESCO Proposal
Between February and May, ten technical visits were conducted to record energy consumption across cabins, staff housing, industrial processes, commercial areas and administrative facilities. EFICENER produced an audit report and presented an ESCO contract proposal, currently under evaluation.
ESCO contracts allow investments to be repaid through the savings generated. In this case, an 8-year payback period is projected for photovoltaic installations, with an estimated lifespan of 20 years.
Opportunities for Improvement
ESCO measures:
- Adjustment of contracted power levels
- Power factor correction
- Reduction of losses in water pumping and distribution
- Replacement of CFL lamps with LED
- Installation of photovoltaic farms
- Incorporation of SAVE charging stations for electric transport
Non-ESCO measures:
- Efficient lighting in previously unlit roadways
- Incorporation of electric vehicles for supervision
- Improvement of electrical panels and grounding systems
- Off-grid lighting in remote areas
- Curve and narrow-pass signaling (beacons)
- Photovoltaic towers for smartphone charging
- Solar water heaters for mate preparation
These actions reflect the Park’s commitment to sustainability, innovation, and the well-being of both visitors and the natural environment.
