Self-consumption of photovoltaic energy in the meat industry

Company with a significant electricity consumption level throughout the day. This energy dependence has a direct effect on the cost of its products and, consequently, on its competitiveness. These types of companies are very vulnerable to tariff rises imposed by the electricity company in question.

Solution

A photovoltaic self-consumption system has been installed so that they can generate their own energy (approx. 25%) for consumption in real time.

Given that consumption is always higher than production, 100% of the energy generated is consumed.

Characteristics

• System’s rated power: 10 kW (11 kWp).
• Estimated life of the installation: 25 years
• Required surface on the roof: 200 m2

Benefits

• Energy saving: 15,500 kWh/year
• Economic saving (25 years): 44,000 €
• Reduction in CO2 emissions: 9.75 tn/year

Investment

• 18,700 € (turnkey)*
• Amortization period: 8 years (approx.)**
• *This value may vary, depending on several variables.
