A new Clean technology for Electricity Generation

1. A New Clean Technology for
Power Generation

2. Power Sector in India
Power is one of the most critical components of infrastructure crucial for the
economic growth and welfare of nations.
India’s power sector is one of the most diversified in the world. Sources of power
generation range from conventional sources such as coal, lignite, natural gas, oil, hydro
and nuclear power to viable non-conventional sources such as wind, solar, and
agricultural and domestic waste.
Electricity demand in the country has increased rapidly and is expected to rise further
in the years to come. In order to meet the increasing demand for electricity in the
country, massive addition to the installed generating capacity is required.
India ranks third among 40 countries in EY’s Renewable Energy Country Attractiveness
Index, on back of strong focus by the government on promoting renewable energy and
implementation of projects in a time bound manner.
Under the 12th FiveYear Plan, the Government has added 93.5 GW of power
generation capacity, thereby surpassing its target of 88.5 GW during the period.
The annual growth rate in renewable energy generation has been estimated to be 27
per cent and 18 per cent for conventional energy.
Around 293 global and domestic companies have committed to generate 266 GW of
solar, wind, mini-hydel and biomass-based power in India over the next 5–10 years.The
initiative would entail an investment of about US$ 310–350 billion.
The Government of India has identified power sector as a key sector of focus so as to
promote sustained industrial growth.

3. The Opportunity
The Indian power sector has an investment potential of Rs 15 trillion (US$ 225
billion) in the next 4–5 years, thereby providing immense opportunities in power
generation, distribution, transmission, and equipment, according to the Govt. of
India.
The government’s immediate goal is to generate two trillion units (kilowatt hours)
of energy by 2019. This means doubling the current production capacity to provide
24x7 electricity for residential, industrial, commercial and agriculture use.
The Government of India is taking a number of steps and initiatives like 10-year
tax exemption for solar energy projects, etc., in order to achieve India's ambitious
renewable energy targets of adding 175 GW of renewable energy, including
addition of 100 GW of solar power, by the year 2022. The government has also
sought to restart the stalled hydro power projects and increase the wind energy
production target to 60 GW by 2022 from the current 20 GW.

4. Goal and Objective
To establish an organization with like minded professionals, investors
and promoters to –
 Perfect the concept and technology for all possible applications and
obtain required patents and certifications.
 To undertake all functions design, development to manufacturing of
all possible products and their marketing.
 To take up turnkey power plant projects with PPA with state and
central Government in India and other clients.
 To work as licensor of the technology for other power project
developers
 Expand to overseas market as a technology provider and power
project developer
 Continue research and development in related products for use in
newer fields

5. Salient Features
 The concept has many applications and already in use; so this
knowledge is in public domain. But it has never been applied
successfully for power generation.
 Conventional production technology is used to produce all the
components.
 This is a complete indigenous product. So can be made available
with less cost.
 The simple structure and configuration facilitates easy and
affordable maintenance.
 The most costly component of the module is the alternator.
 Uses less land compared to other Hydro, Wind and Solar power
generation facility. For a 220 MW power plant comprising of 8 units
will require 300 square meters (1/14th of an acre) of space only
for the units.

6. Salient Features
 This requires external energy to start and minimum energy to keep
it running.The rest energy input is from the renewable source.
 The module uses special green energy technology to harvest the
energy from the renewable source and feeds the alternator.
 With continuous production except stoppage for maintenance it is
suitable for building up base load capacity, thus can replace the
other polluting power plants.
 Uses renewable energy source for power generation and there is
no lack of this resource anywhere. So there is no location
constraint for establishing power plants that use this technology.

7. Possible applications
As this module can generate torque through mechanical means
it can be used for power generation and also for prime
mover as listed below. The modules can be configured
according the required capacity.
 As major power generation system in power plants
reinforcing build up of base load capacity
 As single or multiple unit installations for Industries big, and
medium, Industrial estates, Hospitals big and medium,
University campus, Engineering and medical colleges,
Housing societies,Towns and cluster of villages
 As prime mover for transport vehicles, earth moving
equipment, cranes, mining equipment like excavators
 As prime mover for railway locomotives and ships

8. Some advantages and disadvantages
 Less land requirement makes it more viable.
 No storage system is necessary as these can be used to build up base load
capacity. Production can happen throughout the year. Not dependent upon,
weather, fuel availability.
 The system is scalable for capacity increase within the same space.
 The system is bulky, is not suitable for rooftop installation.
 This is not economical for sub MW capacity, but with no fuel cost it is
advantageous in the long run.
 The maintenance cost is more in comparison to solar installations but
continuous uninterrupted power production and less capital requirement
overcomes this drawback.
 Can be used in railway locomotives, ships, and transport vehicles (no small cars
and utility vehicles) thus reducing consumption of fossil fuels.

9. Differentiators
GRW Power Solutions is a new technology for production of power using renewable
sources. This new technology will be a replacement for the current technologies
available in renewable energy field for production of power. In this regard the
companies now involved in establishing solar and wind farms will be our target
customers. Among the renewable sources Solar source for energy production is
most versatile due to technologies involved. The cost of availability of solar power
is becoming cheaper and cheaper day by day. The following are the differentiating
factors between GRW Power Solutions and prevailing power production
technologies in wind power, solar power, tidal power.
Investment per MW

GRW Power– ₹2.40Wind Power – ₹3.46
Solar Power – ₹2.44 - ₹2.97

10. Differentiators
Solar Power GRW Power
- For Solar farms depending on the technology the
land requirement varies from 2.5 acres per MW to
6.5 acres per MW.
- Scaling up capacity needs more land and may be
not possible due to non availability of land nearby.
- Power evacuation cost is a burden as solar farms
may not be established very near to the grid in most
of the cases due to land constraint.
- Cost for storage of power to maintain supply at
non producing hours.
- Solar modules are ideal for rooftop installations as
long as not using any land for installation on ground.
- Solar modules are ideal for isolated street lights.
-With increased R&D solar modules and power
storage solutions are becoming cheaper day by day.
- Proven technology
- Skilled and experienced man power availability
- Land requirement excluding substation –
• 600 M^2 or 0.15 acre for1MW to 19MW
•1000 M^2 or 0.25 acre for 23MW to 80 MW
•1400 M^2 or 0.35 acre for 82MW to 171 MW
• 1600M^2 or 0.4 acre for 177MW to 233 MW
• 1800M^2 or 0.45 acre for 235MW to 305MW
- Any Power producing unit in a range can be
upgraded to next range without requiring additional
land.
-Due to less space requirement these units can be
established very near to the electricity grid.
-No storage facility is required as clean power can
be produced continuously at constant rate.
-Not suitable for roof top installation .
-Life of the units 20 to 25 years.
- Getting approvals of various authorities and
acceptance of the technology as a viable alternative
for power production requires time and
considerable amount of funding.
