The total investment will be €11,805,195,141, covering Phase 1 and Phase 2 (excluding inflation, which would result in a total of €13,578,034,641), with an 11-year execution period, from the second quarter of 2026 to the year 2035. This amount includes urban development, connection works with general networks, and construction, and will be fully financed by the company.
