About IEL

Intergen Energy Limited ('IEL') is an Indian publicly limited engineering company incorporated

on 13.08.2011 under the Companies Act 1956 (No. 1 of 1956).

The company is active within the fields of water and Sewage Treatment, Infrastructure and

Renewable Energy, and designs, develops and implements projects both on EPC and BOO/T

bases. Intergen operates within Asia, Africa and the Middle East.

IEL has completed a number of government and non government assignment including the

engineering of several water and sewage treatment plants and large rural and urban water

supply schemes including solar powered water treatment plants across a number of locations

and states. IEL is also doing a number of EPC projects with regards to construction of roads and

other infrastructure projects.

IEL endeavours to provide state-of-the-art technology whilst employing a flexible approach

which ensures that indirect costs are kept low, and in turn that profitability is maximised. IEL

works on a strict delivery procedures so as to ensure timely completions and a large turnaround

of projects.

Intergen holds ISO 9001:2008 and ISO 14001:2004 certifications, and is an approved MNRE

(Ministry of New and Renewable Energy) channel partner and accredited system integrator.

Headquartered in Delhi, India, Intergen's key underlying principle is to undertake work which

has a beneficial impact both on people's lives and on the environment as a whole. It does this

through the execution of projects and the acquisition of businesses which fit in to this mould.

The company started with an initial focus in the water and sewage treatment space, in which it

sources, conceives, develops and executes EPC contracts, Government tenders and BOO

projects. The company has a particularly strong presence in the North East of India, where it

has set itself apart thanks to its ability to work on some of the most challenging terrains and

landscapes which India has to offer. The quality of execution which Intergen has demonstrated

has been noted by both Government bodies and private companies alike.

As its reputation grew, the company was solicited for work outside of India, and seeing a very

similar requirement to that in India, formed a joint venture partnership with Stallion Group, a

leading West African business conglomerate, to develop solar-powered water treatment

systems in Nigeria. As it established itself within Nigeria, Intergen was approached to become

part of the Eko Atlantic City project, Nigeria's largest ever land reclamation project which when

complete will house 400,000 residents and 250,000 business people. Intergen was approached

to provide the project with water and sewage treatment systems, and solar street lighting also.

The company is currently assessing potential similar opportunities for water treatment

solutions elsewhere in Africa and in the Middle East also.

Intergen boasts a strong core in-house team, each member of which has years of industry-

leading experience and has been cherry picked to undertake a specific role within the business.

This integrated team has specific niche skills added to it on a project-by-project basis as

required. This approach ensures optimal execution in terms of both quality and cost.

Commensurate with the aim of undertaking ecologically advantageous work, over the past

year, Intergen has acquired stakes and been involved with a number of small start ups that they

believe provide sort of work that is commensurate with the companies remit.

KK Plastic Waste Management Limited (KKP)

KKP is a Bangalore-based recycler of plastics for use in the construction of roads. The Company

has devised an end-to-end process through which it collects plastic waste, sorts this waste and

turns it in to flakes. This resulting flake polymer is called "KK Poly Blend". The KK Poly Blend is

then mixed with the bitumen and asphalt used in the construction of roads. The constructed

roads are more flexible, more durable, cheaper and last longer than conventional roads. The

Company has patented this technology, and to date is the only company to have successfully

commercially implemented such a process, having built over 1,400km of plastic-based roads in

Bangalore to date.

The issue of waste plastics is currently one of the biggest threats to both the Indian and the

global environments, and as well as mitigating this problem and creating better roads, KKP

creates significant employment opportunities for local rag pickers who for the first time are

financially incentivised to collect plastic waste. The collection of one tonne of plastic waste

generates 100 member employment per day and the company currently operates multiple

plastic recycling plants in Bangalore which can process up to 30 metric tonnes of plastics per

day.

JRC Brickworks Limited (JRC)

JRC is a Delhi-based manufacturer of fly ash bricks. Fly ash is a waste product which is produced

as a by-product within coal-fired thermal power stations. Fly ash is harmful to the environment

and in most cases is simply dumped in to landfills. JRC has created a process which helps to

minimise this negative impact on the environment by providing an alternative use for fly ash; its

use as the major component in the production of bricks for the construction industry. As

compared to conventional red clay bricks, fly ash bricks are cheaper, stronger, lighter and more

resistant to water and salinity.

A standard 100 MW thermal power plant generates about 0.15m tonnes of fly ash per annum,

and the Indian Government has recognised the acute environmental problem that fly ash is

causing, and has banned the manufacture of red clay bricks within an 100km radius of all coal

plants.

AquaPlus Technologies (Aqua)

Founded in 2009, Aqua is a manufacturer and fabricator of Water Treatment Systems and

Sewage Treatment Systems. The company boasts strong relationships with central and state

Government departments across India, a highly experienced technical team, long standing

relationships with suppliers, and a reputation for products and maintenance service of the

highest quality.

Against the backdrop of a growing market and growing demand for its products, the company

has exhibited strong year on year growth, yet lacked the financial firepower to be able to

tender for and win the largest projects available. Post acquisition Intergen has provided Aqua

with this financial firepower, and also with further water treatment and sewage treatment

orders.

Going forwards, Intergen will continue in earnest to pursue its goal of becoming a globally

recognised first class infrastructure player with a prime focus on environmentally advantageous

work. In terms of geography, Intergen will build on its current base of operations within India

and Africa, and will also seek to enter further markets worldwide with an initial focus on S.

America. As Intergen grows across verticals and geographies, its primary aim will be to maintain

the high levels of quality and execution with which it has become synonymous, and to ensure

the successful and timely execution of all its projects.

Business Segment

Reverse Osmosis

Reverse osmosis (RO) is a membrane technical filtration method that removes many types of large

molecules and ions from solutions by applying pressure to the solution when it is on one side of a

selective membrane. The result is that the solute is retained on the pressurized side of the membrane

and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not

allow large molecules or ions through the pores (holes), but should allow smaller components of the

solution (such as the solvent) to pass freely.

RO process for water purification does not require thermal energy. Flow through RO system can be

regulated by high pressure pump. The recovery of purified water depends upon various factors including

membrane sizes, membrane pore size, and temperature, operating pressure and membrane surface

area.

Waste Water and Sewage Treatment

Most wastewater is treated in industrial-scale wastewater treatment plants (WWTPs) which may include

physical, chemical and biological treatment processes. The most important aerobic treatment system is

the activated sludge process, based on the maintenance and recirculation of a complex biomass

composed by micro-organisms able to absorb and adsorb the organic matter carried in the wastewater.

Anaerobic processes are widely applied in the treatment of industrial wastewaters and biological sludge.

Some wastewater may be highly treated and reused as reclaimed water. For some waste waters

ecological approaches using reed bed systems such as constructed wetlands may be appropriate.

Modern systems include tertiary treatment by micro filtration or synthetic membranes. After membrane

filtration, the treated wastewater is indistinguishable from waters of natural origin of drinking quality.

Nitrates can be removed from wastewater by microbial de-nitrification, for which a small amount of

catalyst is typically added to provide the bacteria with a source of carbon. Ozone Waste Water

Treatment is also growing in popularity, and requires the use of an ozone generator, which

decontaminates the water as Ozone bubbles percolate through the tank.

Bio-Mass

Biomass can be routed through following different processes for energy conversion:

Direct Combustion

Thermal decomposition of organic matter is carried out in the presence of excess air, liberating heat and

leaving behind incombustible ash.

Fuel + Air ? Heat + Ash + Inert Gases

In the combustion mode, the Biomass and air are combined under efficient and controllable conditions

to provide energy for utilization. The direct combustion of Biomass can be done in two ways:

Fixed Bed Combustion

The combustion of Biomass is usually carried out in fixed bed combustors. The main drawback of fixed

bed combustion is a low combustion efficiency of 70%. It is associated with problems of ash removal and

inability to use effectively high moisture content Biomass. Further, fixed combustion involves high

inventory of fuel over the grate resulting in time consuming start-up and shut down procedures.

Fluidised bed combustion

In a fluidized bed system, a bed of fine particles is fluidized by a gas stream passing upwards through it

at a controlled velocity. The bed is continuously subjected to high rate of mixing and agitation resulting

in high heat and mass transfer rates. Fluidised bed combustion is best suited for burning fuels like rice

husk etc.

The advantages of fluid bed combustion over fixed bed combustion are high combustion efficiency

(95%), multi-fuel combustion facility, and consistent rate of combustion and ability to burn low grade

and high moisture content fuels.

Gasification

Gasification is the thermo-chemical process of obtaining energy from solid matter in a gaseous form. In

principle, the process is a thermal decomposition of organic matter in the presence of limited supply of

air or oxygen to produce combustible gases thus converting calorific value of organic material into a

gaseous energy carrier. The amount of electricity that can be produced from Biomass power systems

can be increased by 50% by replacing steam based generation units with Biomass gasifiers close-coupled

to gas turbines.

Pyrolysis

In contrast to complete combustion of solid carbonaceous material, the process of pyrolysis refers to

combustion in a deficient supply of air / oxygen. The process gives out carbon-mono-oxide and

methane, which are condensed to form tar and aqueous liquor. The latter is then distilled to give

methanol and other organic substances. This process produces three useful fuels - charcoal, oil and gas.

About 70% of the energy in Biomass can be converted to higher forms of energy - charcoal or oil, which

are storable and transportable.

Small Hydro Power

Small Hydropower is a renewable, non-polluting and environmental friendly source of energy. It is

perhaps the oldest renewable energy technique known to the mankind for mechanical energy

conversion as well as electricity generation.

Hydropower represents use of water resources towards low cost energy generation with mature

technology characterized by high efficiency and operational flexibility.

Hydroelectric power is the generation of electric power from the movement of water. A hydroelectric

facility requires a dependable flow of water and a reasonable height of fall of water, called the head. In a

typical installation, water is fed from a reservoir through a channel or pipe into a turbine. The pressure

of the flowing water on the turbine blades causes the shaft to rotate. The rotating shaft is connected to

an electrical generator which converts the motion of the shaft into electrical energy.

Solar Energy

Energy from the sun not only sustains life an earth but is also the source of almost all forms of energy

used by man. Solar energy, experienced by us as heat and light, can be used in a number of ways and for

many applications such as:

Thermal route - using the heat for heating, cooling, drying, water purification and power generation.

Photovoltaic route - converting the light energy into electric energy which can then be used for a variety

of purposes such as lighting, pumping, communications and refrigeration etc.

Producing electricity from solar resource through:

- Concentrating solar thermal

- Solar photovoltaic

Concentrating solar thermal route uses the heat component of solar energy. Heat is used directly or

through an intermediate fluid to generate steam which is expands in steam turbine to produce

electricity.

Solar cells convert solar radiation (sunlight) directly into electricity by photoelectric/photovoltaic effect.

Incident photons (light ray) strike on the photovoltaic cell, and knock off electrons. These free electrons

start flowing through a circuit forming an electrical current.

Photovoltaic module contains a group of photovoltaic cells, connected mostly in series and encapsulated

between a layer of front glass, EVA and back cover. The high transmissivity, toughened glass cover is

used to ensure high light absorption and therefore enhance the performance of the cells. Solar radiation

falls directly upon the photovoltaic cell and produce DC electricity.

Photovoltaic cells absorb both direct and diffuse solar radiation. Generally, flat plate photovoltaic

modules/panels are mounted in a fixed position and tilted towards south (locations in northern

hemisphere) to optimize energy production. However, flat plate PV panels with tracking mechanism

(one/two axis) increase output of solar panels, particularly for high DNI.

The amount of power that a PV panel delivers is proportional to the amount of radiation that falls upon

it. The advantages of PV system as compared to solar thermal are as follows:

- It is modular in nature so that any size of system could be installed.

- It is suitable for relatively colder climates

- It is nearly maintenance free

- Less water requirement

- It does not make any noise

The various types of solar cells used for electricity generation are as follows:

Crystalline

The most common commercial crystalline solar cells are made up from silicon wafers. These account for

about 85%[ ] of the worlds solar PV industry. Silicon wafers either consists of one large singe crystal,

called single crystalline wafers, or consist of crystallites in a single wafer, are known as polycrystalline

(multi-crystalline) silicon wafers. The main advantages of cells produced from mono-crystalline (mono-

Si) and polycrystalline (poly-Si) silicon wafers are: suit relatively small areas and have higher efficiency.

The efficiency achieved by a crystalline solar cell depends on the processing technology used to make

the solar cell. The most commonly used technology to make wafer-based silicon solar cells is screen-

printed technology.

Thin Film

Thin film solar cells are made up from a variety of materials, with the key features being that the

thickness of the cells is a few microns. Thin film solar cells are made from amorphous silicon (a-Si),

cadmium telluride (CdTe) and copper indium di-selenide (CIS). Thin film technology is comparatively

cheaper, but produces less output per unit area due to its lower efficiency, so it requires large area per

unit output.

The main advantages of cells produced from thin films are low cost of production and they can be made

with requisite shape as per the requirement. But, unfortunately there are limitations of utility

properties. However, it is possible to improve the utility properties of amorphous cells by means of

changing the cross section of the window layer to improve sun light collection efficiency.

Other

There are some other PV materials for solar cells like string ribbon silicon wafers (ribbon-hetero-junction

with intrinsic thin layer hybrid silicon solar cell (HIT) and concentrator photovoltaic solar cell etc.

Waste to Energy

Wastes generated from various sources can be converted to energy through different technologies such

as Anaerobic digestion / Biomethanation, Combustion / Incineration, Pyrolysis / Gasification, Landfill Gas

recovery, Plasma arc. The organic fraction of the waste need to be segregated and fed into required

process. The option of technologies is detailed in Biomass segment.

Wind Energy

Wind Energy is the kinetic energy associated with the movement of atmospheric air. Wind Energy

Systems convert this kinetic energy to more useful forms of power. Wind turbine transforms the energy

in the wind into mechanical power, further converting to electric power to generate electricity. Wind

turbine can be used singly or in clusters called 'Wind Farms'. Small wind turbines called aero-generators

can be used for water pumping, battery charging etc.

Green building concepts:

Green Building, an energy efficient sustainable building is designed in an ecological and resource

efficient manner with an objective of healthy environment, improves productivity and using energy and

other resources efficiently. It mainly focussed on Integration of Renewable Energy Technologies in

particular Solar Energy, Building material & Energy Conservation. It emphasis an effective utilisation of

Energy and analysis of option of alternate energy with an overall reduction of energy consumption.
