Generation
Planning
A
variety of new generation options are potentially available for
consideration by Bangladesh to meet the growing demand. In order to
provide preliminary comparisons, to reduce the number of alternative
options and to assist in the general locating of thermal candidates,
always a screening analysis is undertaken. The screening takes account
of environmental mitigation, fuel transportation and power
transmission costs. This compares the relative attractiveness of
different options at various plant factors.

Critical
factors governing the commitment that BPDB should make to the
different types of thermal plant are fuel availability, deliverability
to different parts of Bangladesh, and an adequate supply of cooling
water. A detailed review of indigenous and imported coal, gas and
liquid fuel resources are taken into consideration of generation
planning.
Additional
factors that are taken into account during generation planning in
locating thermal generating plants are the regional balance between
supply and demand, environmental factors, cooling water availability
and proximity to the transmission grid.
All
generation options, including their cost and technical performance
data, the earliest dates at which they could be available and the
maximum capacity available for each option are factored into the
generation planning process.
The
generation planning model used by BPDB is the Wien Automatic System
Planning Program (WASP III Plus), which simulates the operation of
the generating system for each year of the planning period, and for
the alternative combinations of new generation additions as provided
by the user. Using dynamic programming, the model then sorts among all
the alternative sequences to select the one that is both least cost
and meets the specified levels of generation reliability in each year.
Each
alternative set of assumptions concerning the availability and timing
of the new generation options are analyzed using the WASP model. The
results of the WASP analyses are constrained to least-cost expansion
sequences
