7 VALORAGUA and Core programs of WASP were developed in FORTRAN and compiled with oldversions. Most computers in DOED use 32 bit Windows environment and there are alsomethods of running 32 bit software in 64bit environment (unless these are device drivers).So,thisshouldnotbeanissue.

8 Hydropower plants are to be categorized in terms of runoff river plant and storage plant. Runoff river plants are further categorized in terms of simple run off and daily poundage run off.Take this matter into consideration while writing the inception report. (eg. chapter 3.2.9 (a) &3.2.12etc.)

4 In the context of competition at electricity generation, transmission and distribution in thecountry, it is more pertinent to carry out system analyses under different scenarios and predicttherespectiveoptimalsolutions.

Agreed

5 This guideline shall serve as reference book for potential power developers and the buyers oftheir products (read:electricity) to arrive at mutally beneficial rates when concluding PowerPurchaseAgreements.

Agreed

6 Thesignificanceofboththeavailibilityofpowergenerationandpresenceofdemandforpoweris imminent in any electric power system. As the creation of these facilities have significantlead times, it is necessary to assess demand and create necessary facilities on timely manner.The guideline, therefore, shall cover the transmission system as well. The distribution systemsmay not be considered separately but their loads can be lumped and connected to thetransmission/subtransmissionvoltagelevels.

Agreed

7 The Consultant shall provide the customised model for Power System Optimization clearlyidentifying the system variables/parameters and methods of obtaining them. Often, theoptimization process does not result in optimal/best solution because of wrong/bad choice ofsystem variables/parameters. This issue has to be clearly spelt out and necessary measuresrecommended.
