Field study comprises of a detailed feasibility / technical survey of the areas to be electrified. The study includes detailed data collection, projection of load for next 10 years considering economic and demographic profiles, detailing of transmission line / sub transmission line routes and location of sub stations on basis of load factor. This survey is most efficiently carried out by use of geographical information systems (GIS) techniques using portable global position systems total stations (GPS/TS). Use of such techniques gives excellent accuracy and the survey can be completed in a short time. As the data is totally digitized, advanced software is used to process the information and arrive at the desired results. The various aspects of the survey are as follows:

· Digitization of various geographical /immovable features.

· Collection of attribute data e.g. loads centers, load profiles, indexing of consumers, pole identifications, distribution line lengths proposed.

· Creating of asset management system by processing of all the collected data.

· Analysis of the proposed system to arrive at the power losses expected along with the voltage profile.

· Creation of digitized maps of the locality with the electrical system preparation of a least cost network in order to rationalize use of available resources.

· Preparation of a bill of material.

In accordance with the Bill of Material derived from the field survey details and duly discussed and approved by the owner and as per the finalized specifications, material and equipment is procured and supplied.

3. Project management and field execution

Urja undertakes the complete responsibility of the Management and Execution of the project at the site. Various services provided by Urja are as follows:

· Provision of technical experts to help and guide the installation of the network assets.

· Monitoring of the schedules and advice on timely completion.

· Site training of local engineers and contractors in asset installation and maintenance.

· Training of local engineers at the manufacturers works in maintenance of assets.

· Assistance during the initial running phase of the project to monitor the achievement of the desired operating parameters.

As extensive use is made of locally available human capital, we ensure there is a high level of up gradation of the skills of the local engineers, contractors and skilled personnel.

Some of the options for electrical energy generation both conventional as well as non-conventional sources includes:

· Conventional methods based on fossil fuels.

· Solar energy based localized solar power sources.
These systems have the advantage of low cost, short implementation period, maintenance free, and are ideally suited for remote areas where there is no electricity and where provision of electricity from the national/regional grid would entail significant capital investment for an overhead line link up.

· Biomass, biogas based electrical generating units using locally available bio waste like agricultural waste, wood/wood waste. Low initial and running cost and utilization of locally available resources are the advantage of such systems.

· Micro hydel projects suitable for localized distribution of power. Such power sources could be in unit sizes as low as 10kw and up to 500kw, depending upon the load requirement and also the nature of natural hydro sources available in the area. At later stages, such generating stations can be linked to the national/regional grid also.

· Wind energy solutions for electrical generation can be provided in areas which have a significant annualized wind flow available, by setting up ‘Wind Farms’. Part from being non polluting and not dependent on any supply of fuel, such installations have virtually nil running cost.
