Objectives
-
To develop regional energy plan models based on decision
support system using spatial and temporal analyses tools
such as Geographic Information System and multi temporal
satellite imagery. This includes
- Sectorwise Energy Demand
This involves survey of the present energy consumption
in domestic, agriculture, industrial, commercial and services
sector for various enduses covering the magnitude, types of
energy sources, trends and preferences in consumption.
- Assessment of Energy Supply
This involves analyses of the present supply system,
assessment of woody and other biomass sources and study
of supply system of commercial sources of energy.
- Spatial Mapping
This involves mapping of Energy Resources Such as Hydro
and Bio Resources in addition to other Resources such
as wind, solar etc..
- Imagery Analysis
This involves analysis of Low and High Resolution, Multi
Temporal Imagery with GIS data to develop Agro-Ecological
zonation of the region to estimate the available biomass
supply and a more detailed land cover classification.
- Field data Collection- Ground truthing
These would be supplemented with field data (collected
by experienced field staff using random sampling techniques)
consisting of vegetation cover, type of vegetation, wind,
solar, hydro resources and watershed data to maximise
efficiency.
- Regional Agro Ecological Zonation
This provides consistent sampling frame to spatially link
the results of energy demand and supply surveys, and to
identify energy surplus and deficit regions.
-
Identification of Development Priorities of the District and
the hierarchy of the energy needs in the priorities would be
established.
-
Study of Spatial Distribution of Energy Supply and Demand
(talukwise) using G.I.S and estimation of the gap between
demand and supply. Mapping of sectorwise energy demand;
Industries sector (spatial distribution and temporal
variation), Household sector (energy demand mapping along
with level of literacy, community and land holding
details), etc.
-
Development of Regional Energy Plan to meet the energy
demand in accordance with the development priorities.
-
Capabilities to Generate and Assess Energy Scenarios:
Model developed would enable to generate scenarios of
possible future energy demand and viable supply mixes
to meet the demand.
-
To appraise and compare alternative methodologies for regional
energy and environmental forecasting, planning
-
To describe and analyse patterns of regional energy use and
to develop insight into their relationships to technical and
socio-economic variables
-
To develop concept and methodologies for energy environment
management
-
Using the above methodologies to examine alternative energy
strategies for environmentally prone regions (due to various
reasons), to explore their implications from various
perspectives using indicators related to environmental impact,
energy use, and to investigate whether these strategies
represent a viable choice for a given society.
Regional issues to be studied
This issues need to be studied, in order to be sure that they
differ according to the regions but, nevertheless, there are
several concerns common to many regions.
These issues are
- Energy Supply
What are the resources and environmental implications of
satisfying future energy demand by the various viable
alternative energy sources ?
- Human settlements
How is energy use related to settlement, density, size,
energy supply technology ?
What role should these factors play in land-use planning,
etc. ?
- Energy use patterns
What are the energy implications of continuing the
present evolution of energy use patterns ?
How are these modified by the use of alternate energy
use technology ?
Apart from these, impacts that occur within the region because
of energy use within the region, impact that occur outside the
region because of energy use within the region, impact that
occur within the region because of energy export to other
regions and finally impacts that occur outside the region because
of energy export to other region.
Thus, the model simulates regional energy system within a
framework that includes energy demand, regional system and
environmental impacts. Also illustrates, significant structural
differences or similarities between the energy environmental
characteristics of the region.
Regional Disaggregation
The aspect of geographical distribution is extremely important
and sometimes decisive for the assessment of the resource / demand
situation. By regionally disaggregating the available data, together
with socio-economic information (e.g.: population densities,
cultural diversity, land utilization/holdings, transportation
facilities etc.) would contribute substantially to a meaningful
analysis and projection of energy supply/demand situation.
The bulk of the energy used in region are consumed in four main sectors
- Domestic : cooking, heating/cooling, lighting
- Agriculture : crop and livestock production
- Industrial : heating, lighting, welding, etc.
- Supply services : transportation, hospitals, hotels, etc.
Thus the model designed would account for
Regional and Seasonal Variations in the Quantity of Energy
consumption and Energy Resource Availability.
Records of the usage of fuel which are not Purchased but Gathered
free of cost.
Animate Sources of Energy in the Input Analysis to account for
Human, Animal power used in Traditional Agricultural practices,
Domestic, Industrial operations etc.
- Energy alternatives and scope for conservation
This work hence involves
Estimation of sectorwise spatial energy demand in Domestic
(based on demographic, literacy rate, community and land holding
by household information), Industry, Agriculture, Commercial
and services sectors.
Primary survey would be carried out in domestic sector in
each taluks based on stratified random sampling approach
(stratification based on, communitywise, land holding wise,
family income etc)
Groupwise, Talukwise Energy Deamnd in Industries sector
Talukwise, Categorywise Energy demand in agriculture (for
different crops)
Spatial mapping : Talukwise, Sourcewise energy demand
Spatial distribution of energy supply (mapping of various
resources), to provide inventory of woody biomass, crop
residues, hydro resources, etc.
- Use of GIS in hydro resources development
- This involves spatial mapping of streams with geographic
details
- Collection of water yield information of sample streams
in each river basin of a district.
- Agro Ecological zonation of the region
With spatial and temporal information and GIS data on
rainfall, topography, land use patterns, Use of multi stage
sampling design with Landsat TM imagery for detailed sub
sampling for regional inventory of woody vegetation and
crop residues will be carried out.
Development of Energy Model based on Decision Support System
consisting of modules for computing sectorwise energy demand and
sourcewise energy availability, possible supply options and their
implications for each of the demand scenario
Justification
The regional energy plan developed based on these techniques
could be successfully applied to other regions with different
energy supply strategies. Identification of energy surplus and
deficit region should enable the challenge of conserving regional
natural resources in balance with its energy demand to be met
in a sustainable manner. The development of energy plan with GIS
would also provide spatial dimension.
