World Bank allotted 500 Mn to SBI to lend aggregators

ADB plans to give 500 Mn to Punjab National Bank

Home loan and Home improvement loan

Net Metering: Almost 25 states have policies

Draft of 1000 MW Rooftop project under the SECI Subsidy Scheme is

in the final stage

BOM application need not to be routed through SNA

Accelerated Depreciation Benefit

Grid Power availability

Challenges

Lack of availability workable spaces

No benefits available for the Industrial & Commercial customers

Lack of education/interest of the Non-profitable organizations who

are having the benefits of the Govt. subsidy

Net Metering policy implementation

Solar Energy to move from Class to Mass

Way forward

Taluka wise solar targets

Interest subvention across value chain

High priority for adaption of new solar storage technologies

Every house/farm to use net metering

Massive R&D – Can we reduce the space to half?

Uniform Net Metering Policy throughout the country

Large deployment of Micro and minigrids

Extensive awareness amongst masses

Net Metering Policy - Update

State Wise Net metering Policy

Process - Net Metering / Gross Metering

Issues - Net Metering / Gross Metering

1. Eligibility Criteria

2. SPV : Connectivity Voltage

Eligibility Criterion for installation of Solar PV system:

The consumer LT/HT consumer is MSEDCL‟s area can install a solar PV

system less than 1 MW to cater all or part of his own electricity load

requirement. This includes consumer catering to a common load such as

Housing Society.

Such solar generation system may be owned and operated by the consumer

itself or by third party leasing such system to the consumer.

The HT consumers (11 KV and above) may install and connect

Rooftop Solar PV systems at their LT bus bar system.

Issues - Net Metering / Gross Metering

3. SPV : Meter Location w.r.t. connectivity approval

Inter-connection with the Distribution network:

The interconnection point for installation of Rooftop solar PV systems under Net-

metering Regulations, 2015 is defined as under:

“Inter-connection Point” means the interface of the Solar PV Systems with the

outgoing terminals of the meter/Distribution Licensee‟s cut-outs/switchgear

fixed in the premises of the Eligible Consumer:

Provided that, in the case of an Eligible Consumer connected at the High

Tension („HT‟) level, the „inter-connection point‟ shall mean the interface of the

Solar PV System with outgoing terminals of the Distribution Licensee‟s meeting

cubicle placed before such Consumer‟s apparatus.

However, in case HT (11 KV and above) consumer is installing the net metering

Solar PV system, with the connectivity at LT Bus bar system in their premises,

the net meter shall be installed on the HT side of the Transformer.

Issues - Net Metering / Gross Metering

4. Supply of Meter & Meter specification

The Net Meter in the premises of the Eligible Consumer shall be procured and

installed by MSEDCL at its own cost and in accordance with the provisions of

the Electricity Supply Code:

If the Eligible Consumer is within the ambit of Time-Of-Day (ToD) Tariff, the Net

Meter installed shall be capable of recording ToD consumption and generation.

MSEDCL shall replace the meter of an existing Eligible Consumer with a Net

Meter.

The Eligible Consumer may opt to procure,

at his cost, the Net Meter for testing

and installation by the MSEDCL.

Solar Floatovoltaics – November 2015

Using unutilized water bodies

Solar Floatovoltaics – Objectives

To build state of the art pilot project

Industry – Academy Collaboration

First in India for installation

Duplicating the same philosophy in larger plants

Increase in output vice-versa, Land mounted plants

Lake beatification

Training students

The floating platform is modular in nature and made of fibreglass-

reinforced plastic (FRP) with polyurethane (PU) foam filled up to

ensure it doesn’t sink.

Solar Floatovoltaics – Concept

The solar photovoltaic power generator consists of PID free solar

modules in series and parallel connections that convert solar

radiations into DC electrical power at the predetermined range of

voltages

The individual solar cells are connected in a module [in series

connection] that is hermetically sealed to survive in rugged weather

conditions and ensure optimum performance as well as minimum

degradation of all the equipment's used

Conserving the scarce land resource

Solar Floatovoltaics – Advantages

Generate electrical energy from unused water bodies

Reduce Water evaporation

Increase in Energy produced due to the ‘cooling effect’

No environmental disruption – land excavation, 100 % recyclable

Slow growth of algae in the reservoirs – reduce chemicals

Speedy Drinking water reclamation through aerators/circulators
