Evaluation of the Water Saving Scenario for Integrated Energy and Environmental Management and its Modeling Using LEAP Software (Case study: Energy system around Jajrood River)

Increasing energy consumption by reducing natural resources and contaminating the environment is a serious threat to human. Therefore, wise use and planning is important in this regard. Present study carried out to assess integrated energy and environmental management using LEAP software around Jajrood River

  Supply system (production, import, transmission and distribution of Latyan hydroelectric power plant), water demand of Jajrood River (urban, agricultural and industrial consumption) and environmental impacts of energy for the determined physical boundary range were modeled by using the capabilities of the LEAP software. Then, the results of model implementation in the reference scenario and scenario of water consumption optimization policies contains the different non-price strategies (household, agricultural and industrial sectors) were compared in a 10-year period.

Energy demand in water sector and the supply of electricity in the base year (2016) were 506/4 and 5607/4 MkWh, respectively, which is expected to reach 651/2 and 7162/9 MkWh in 2026 under the reference scenario. While the total energy demand in the water sector and electricity supply of this region will be 422/5 and 7028/5 MkWh, in the water saving scenario. The carbon dioxide emission in the reference scenario will be increased from 6/43 Mt in the base year to 7/94Mt in 2026. While it will be 7/92 Mt under the proposed scenario.

By implementing the water saving scenario in the studied area, water consumption will decrease to 100 Mm3per year. Also it will be reduced 32/9 percent energy consumption and 20000 tons of greenhouse gas emissions in the year-end of the plan, which will be important in improving the environment.
