The installation feeds electricity directly into the Edemsa distribution network rather than consuming it on-site. Generation capacity links to 20 network interconnection contracts corresponding to Irrigación facilities, compensating electricity consumption across provincial offices except three southern sub-delegations along the Diamante, Atuel, and Malargüe jurisdictions that already operate independent panel systems.
Marinelli indicated investment recovery timelines shortened dramatically from 20 years to five years due to declining panel costs and rising conventional energy prices, making the project financially viable after years of planning. The park’s environmental impact equals annual carbon dioxide capture by 6,000 trees according to official calculations.
Three contractors executed the public tender award: Sumpetrol SRL installed the photovoltaic system, Ceralfa SA built the transformer substation and underground medium-voltage lines, and Ruta Dorada SA mounted perimeter fencing with electronic security monitored in real time from Tunuyán headquarters.
The water authority’s reasoning connects renewable energy adoption directly to water management under climate stress. Since Mendoza’s rivers depend on high-mountain snowmelt becoming less predictable with climate change, operational independence from conventional energy sources strengthens resilience against future scarcity scenarios. Irrigación frames the solar park within its Provincial Water Plan, treating water management and energy transition as integrated challenges rather than separate policy tracks. The installation positions a public water utility as net energy contributor while reducing dependence on external power sources for core operations.
