4MARKET LANDSCAPE
Low Energy
access and
average
consumption
 In Sub-Saharan Africa over 60% of population don’t have access to electricity compared to 30% in South
Asia.
 Average consumption of electricity has a potential to grow fast from a low base.
Current average consumption in Saharan Africa is 497 kWh/capita/year and in South Asia is 707 kWh/capita/year.
This is very low compared to 12,973 kWh in the US, 5,130 kWh in the UK and 3.927 kWh in China. The global
average electricity consumption is 3,500 kWh.
 GDP and populations are expected to grow fast
(i) Between 2017 -2019, GDP growth forecast to be over 7% in South Asia and over 3% in Sub-
Saharan Africa.
(ii) By 2020, populations are expected to grow by 500m people (40%) in Africa and 200m (15%) in India.
Cost
Competitiveness
for new entrants
 Rapid fall in the cost of Renewables, making them cheaper than centralized fossil generation.
(if they can be financed at a reasonable cost of capital).
 Inefficiencies of state-owned grid operators may lead to increase in tariff despite subsidies.
Markets open to
private sector
partnership
 Auctions for renewables PPAs are becoming an established entry route for IPPs.
 Many countries are (slowly) embarking on processes of vertical unbundling and part-privatization of
the power sector (eg Kenya, Nigeria, Ghana).

UTILITY OF THE FUTURE
New Rules of The Game

6. .TATA Power – DDL :Confidential
6KEY CHALLENGES ENVISAGED
URBAN AREAS
 Issues of voltage imbalance, transients, and
harmonics.
 No clear and structured regulations on Power
Quality.
 Absence of accurate load forecasting
mechanisms.
 Impact of Solar Injection and Electric vehicle
penetration on the Network.
A study shows:
 Direct costs of downtime in India are in the tune
of 293 Million USD per annum.
 ~ 57% are due to voltage sags and short
interruptions.
 ~ 35% are due to transients and surges.
 Cost of prevention may be less than 10% of
the cost of problems.
RURAL AREAS
 With 78% of villages electrified in India, the rural
households in the states of Bihar, Jharkhand,
Odisha and Uttar Pradesh which receive power
supply for less than two hours on an average in a
day is very high (67.5%).
 The rural households which receive power supply
for less than two hours on an average in the
evening , for above states, is also high (72%).
 Viability of Off- Grid connectivity needs attention

2030 – A
better
rural
economy
Solar Home Systems is a
suitable options for smaller
homes up to 200 watt and
running DC appliances
Hybrid Micro Grid Systems
can be used for centralized
village power supply by serving
a mini-grid to satisfy modern
domestic needs as well as
public services and the
development of a local economy
Solar and Biomass plant with
Energy Storage for a reliable power
supply. Such power systems can be
individually designed and contain
batteries and smart inverters.
Virtual gird extension -
Supply from battery/energy
storage to small villages
where RE is poor and Grid
extension is difficult.

can store energy
locally
Data analytics will lead to
improved infrastructure
management and
operational efficiency
Electric Vehicles a
cutting edge
technology to address
to climate change and
oil imports
Intelligent Substation: shares
all information on control,
protection measurement and
monitoring equipment through
one bus by
applying both “digital technology”
and “IT-related technology.”

dramatically more efficient
ADMS
Power Management & Weather
Forecasting : High Tech & accurate
weather forecasting system with
refined logarithm for calculation of
discom power need
The Future – From an urban perspective
160 GW of solar and wind may
generate 370 TWh of energy
annually. This shall meet 22% of
India’s electricity demand in 2022
and reduce 21% of power sector
carbon dioxide emissions as
compared to the case where no
new RE capacity is built until 2022.
Power system balancing
with 100 GW of solar power
and 10 GW of wind power
is to be achieved.
National and regional
coordination of scheduling
and dispatch will ease RE
grid integration.
The peak system-wide
1-hour up-ramp increases by
27% compared to a system
with no new RE, to almost 32
GW.
