Abstract
Rapid urbanization has made Kathmandu Valley one of the fastest growing metropolitan cities
in South Asia, resulting to higher energy demand. Kirtipur municipality has the highest
population growth rate of 4.47% leading to higher energy demand in near future. The recent
blockade has revealed the current energy security of Nepal. This research deals with the current
energy consumption pattern and energy demand of Kirtipur municipality and Sustainable
energy planning with inclusion of Renewable energy. A primary survey was conducted with
the household questionnaire and the secondary data were collected from various resources.
Data collected were further analyzed on Microsoft-Excel to find out the current energy
consumption in the case area. And further analyzed on the Long- Range Energy Alternative
Planning System with the energy model with bottom to top approach.
The total energy consumption of Kirtipur municipality was 261.5 TJ in 2018. Cooking was the
most energy intensive end use and use of import fuel Liquefied Petroleum Gas has the higher
demand. If none of the interventions are made in near future and the current energy
consumption trend is continued the sustainable goal for multitier matrix cannot be meet by
2030 i.e. electricity consumption per household per year should be more than 3000Kwh. Two scenarios Electrification by Hydro Electricity (EHE) and Sustainable Development Goal
(SDG) were developed with the fuel switching to clean energy and energy efficient technology
i.e. Hydro Electricity, Solar electricity and Solar energy. The SDG scenario moreover focuses
on the electricity generation from the Rooftop Solar PV resulting to 54% of Total Electricity
demand can be substituted by the electricity generated through the rooftop solar PV. The self-
generation of electricity from the Solar PV not only minimize the Grid Load but also provides
the energy security and reduce Green House Gas emission. Electricity can be self-generated
with the Solar roof Photovoltaics so for the further development of the Roof top Solar home
system model design of Solar roof Photovoltaics has been done as per the building bye laws of
Kirtipur municipality. The social use of the roof of the house has also been taken as the factors
affecting for the model design of Roof top Solar PV. The policies should be driven by strategies
for utilization of indigenous renewable resources instead of importing petroleum products.
With the effective policy intervention, the energy demand and the emissions and the economic
aspects can be minimized for the sustainable energy planning.
