    "There is again an electricity demand (this demand is constant between 2019 and 2022) and several power plant types compete to meet the demand, based on their cost: gas, coal, solar PV, wind and hydro. The hydro power plant, in order to work, is taking water from a dam, fed by a river. The relation between electricity generated and water flow in the turbine is the following:\n",
