Solar Policies & Regulations

State Government had introduced ‘Gujarat Solar Policy-2009’ in

January, 2009 and achieved more than 1000 MW Solar Installation in

short span of 5 years.

On expiry of 5 Year Period, Government has introduced Solar Policy-

2015 to scale up the Solar Power Generation in a sustainable manner;

which is operative since 31st March-2020

Introduced Roof Top Solar PV with Net Metering on Government,

Residential, Commercial, Industrial Building

Net Metering Regulation -2016

Gujarat Wind-Solar Hybrid Power Policy

Policy for development of Small Scale Distributed Solar Projects-2019

Highlights of Gujarat Solar Policy 2015

Objective to encourage Solar Roof Top up to 1KW capacity

Encourages participation from the investor in MW projects with Solar PVand Solar Thermal

Applicable for existing Residential, Government, Industrial, Commercialconsumers

Equally applicable for other solar projects with various objectives likeCaptive Consumption, Sale of Power to DISCOMs, with RECmechanism, NSM objective

For Agriculture Solar Pumps, Canal Top and Canal Bank Power Projects

Standardized Grid Connectivity and norms for Evacuation, Metering &Energy Audit

Fixing of GEDA as State Nodal and GPCL as Facilitating Agencies.

Implementation Profile

Scheme applicable for Grid connected Farmers i.e. the existing Agriculture consumers.

At least 70% of the existing consumers of the individual distribution feeder should participate in thescheme.

The capacity of grid Connected Solar PV would be 1.25 times of Contract Load in HP. Farmer canalso install additional Solar PV Capacity with limited scheme benefit

e.g. 10 HP AG Connection 12.5 KW Solar PV System

The selected feeder shall be provided 3-Phase Power Supply from for 12 Hours during Day time from

sunrise to sunset

Capital cost sharing

• 30%, CFA

• 30%, GoG Loan

• 35%, GoG Loan on behalf of farmer, Loan period is for 7 years.

• 5%, Farmer Upfront Payment

Farmer Revenue on net generation (i.e. generation minus consumption)

• Rs. 3.50 /kWh, Feed-in Tariff by DisCom on net generation

• Rs. 3.50 /kWh, Evacuation-based Incentive (EBI) as Govt. of Gujarat Subsidy, for 7 years, up to 1,000kWh/KW/yearNote: EBI is a generation-based subsidy by Govt. of Gujarat to match MNRE’s 30% capital subsidy.

Benefits To Farmers

The ownership of Solar System is of Farmer after Loan period

completion

Permanent Income to Farmer for injecting surplus energy into grid.

12 Hours of power supply during day time with Grid support

It is possible to grow crop under the solar panel as well.

Social Empowerment of farmer

Consolidation of Rural Economy by Local employment generation

opportunity

10


Benefits To Society And Environment

One third reduction of generation of electricity through Non-

Renewable sources and preservation of Environment.

Due to distributed solar generation, land requirement for solar parks,

expensive infrastructural modifications could be avoided.

Maximum utilization of installed distribution network.

Reduction in Transmission and Distribution Losses.

Reduction in burden of agriculture subsidy.

Reduction in cross subsidy to other consumers

Conservation of Energy and Water
