Overview

Energy Demand increment day by day causing energy crisis in world

Above 80% of Energy from fossil fuel in world Increasing cost of fossils fuels and dependency

on its import ,GHG emission is big challenge Necessitated an urgent search for alternative

energy sources to meet up the present day demands

Renewable energy is the next step to fill out the gap of energy crisis in the future

Introduction

Nepal a victim of energy crisisNepal rich in renewable energy potential and poor

in fossil fuel resources but heavy import of fuel causing heavy imbalance

Major electricity source hydropower and rest fossil fuel

The story of power position in Nepal is that of highest potential and lowest consumption and generation.

Nepal a land lock country and here the import of fossil fuel is a big problem ,cost increasing day by day

Wind energy possibility to rural areas far fromINPS grid Solar energy is availaible in every areas with good insolation average

of 4.7 Kwhr/m2.Solar power plant can be erected in low time Solar energy is free and no GHG emission only problem is that its

initial cost is heavy and hard to finance. Solar energy can be converted to electricity by solar thermal power

plant and solar PV power plant Cost of generation is lower for Solar PV power plant than thermal Germany getting half of insolation has increased installation from 6

GWp to 32 Gwp in 5 years Solar PV grid tied system have been feasible in many countries as its

overall cost has been decreasing Its time for study on large scale PV plant and implementation as

technology is becoming mature day by day with decrease in cost of panels and increase of efficiency.

Overview of utility solar power plant

Why Utility Grid Tied Solar PV plant?Currently nation facing severe Loadshedding even at day big

impact to industrialist and institution and offices.Grid Tied Rooftop revolution is yet to take place due to lack of

appropriate rules,policies,subsidiesNEA is only the service oriented utility responsibile to tackle

energy crisis should have a proper energy mixHydropower taking longer period than expected,Thermal plant

causing huge loss to nationFaster Installation, Lower maintenanceNo GHG emissions as compare to diesel and Multifuel plantDevelop appropriate professionalism in Solar PV sectorCost effective in comparison to thermal plantCan be controlled easily thus more reliable and safe operation.

Introduction Contd…

Energy demand increasing at faster pace than Energy AvailaibilityLoadshedding hours of previous year was 18 hrs which decrease to

13 hrs this year and expected to increase in forthcoming yearsWe are bearing load shedding even at day when we have plenty of

solar energy potentialProper energy mix and use of renewable energy is must to solve the

problem To increase energy availability at a quick rate ,large scale Solar

grid tied PV would be fruitful as it has lower time of installation. Solar PV power plant can be utilized to fulfill energy demand and

decrease use of diesel generator to extent.Major significant cost in erection of PVplant is the high cost of land and availaibility of land near load center which increase cost per unit.

Hydropower area may be suitable for minimising overall cost.

Problem Statement

To carry out techno-economic feasibility analysis of grid connected utility scale solar PV system (selected area – NEA hydropower project).

Other objective Site Selection of NEA hydropower project area for utility solar PV plant

installation Considering grid capability,amount of insolation,area possesed for >=1MWp)

Estimate the grid capability to inject solar photovoltaic power in selected site

Financial analysis of the project and check requirement of subsidy from government to make feasible

To model the complete grid connected solar PV system for selected area using PVSYST

To suggest scheme for connecting solar based plants with thestation electric supply system for hydro electric power plants.

Recommend possible tasks for mitigation of day load shedding

Methodology

The Grid connected PV has been studied and implemented successfully in many countries specially developed countries like Germany, Japan, Italy,Greece etc. In context of Nepal the Grid connection of PV power has just been beginning.

Grid connected PV system without storage has lower cost as batteries have become more expensive

Grid connected system of 1 kwp was installed for R&D purpose in CES , 3 kwp in NEA center and 1 kwp with battery backup in RIDS office.

Research shows their feasibility in terms of economics and safety as well.

In large scale only grid tied solar plant is 680.4 Kwp at sundarighat at KUKL premises.It is fully operational. Loss of energy is occuring due to load shedding

As Grid connected PV system only works when grid is functional for safety purpose.

Literature Review

D. Chianese, D. Pittet, J.N. Shrestha, D. Sharma, A. Zahnd, N. Sanjel, M. Shah and M. Uphadyaya present a paper on Feasibility study on Grid connected PV system in Nepal . Paper concludes climatic conditions of Nepal ideal for solar energy technology. Initial investment high but paid off by a high production and by cost of 19.6NRs/kWh is by far less than produced by systems at use in households during load shedding periods (inverter-batteries: 54.0NRs/kWh;genset: 55.4 NRs/kWh), or by thermal power plant (ca. 30NRs/kWh).

A thesis on “Study on grid connected PV in Nepal” by N. Bhattarai, Pulchowk Campus, 2004 has studied the grid connection with solar panels and STAC research focused on the Energy opportunities of BIPV system at CES where loss of energy (excess energy after charging battery) have been considered. Economic analysis of four different scenarios have been determined and solar grid connected system with some subsidy has been found to be feasible.

Literature Review Continued

A thesis on” Performance analysis of one kilowatt grid connected solar photovoltaic (PV) electric system.” by Ajay Bhattarai, Pulchowk Campus, 2069 performs analysis for 1kWp grid connected solar PV system at (CES),Performance grid tied solar PV by calculating different performance indices like performance ratio, different yields and eficiencies. The effect of solar irradiance on PV array output and inverter efficiency analyzed . The analysis of data indicates that the average final yield was 2.31kWh/day; array yield was 2.64 kWh/day and performance ratio of 0.488 under the normal load shedding. The financial analysis was done for current load shedding pattern and the condition without the load shedding.Per unit cost of electricity was found to be NRs 16.63.

A thesis on” Techno – Economic Analysis of Grid Connected Rooftop Solar PhotovoltaicSystem (A case study of Pulchowk Campus) by Reena Shrestha, Pulchowk Campus, 2069 presents studies on PV grid connected systems in roof top of pulchowk campus. Per unit cost of the project was found to be 10.3 cents without considering project area land cost. If we considered land cost too, per unit cost could be greater that this value. Total cost of the project will be returned in 11 years if the discount rate is considered as 9 % and PPA rate is taken as 23 cents with 2% escalation rate.
