where [K.sub.] and [K.sub.q] are penalty factors for the slack thermal unit
and water discharge, respectively; [P.sub.sl,m,d] is the generation of the slack thermal unit
1 at the [m.sup.th] subinterval of the [d.sup.th] nest calculated using (13).
Many researchers' have forwarded various solution techniques to solve such problem but due to extreme nonlinearity and compounded structure of hydro and thermal units
, the process of finding feasible and optimal solution is quite tough and time-consuming.
As the starting date for thermal unit
accumulation increased from DOY 100 to 200, the time required to accumulate 200[degrees]C d progressively decreased from 22 to 10 d, which reflects the increasing temperatures for the later starting dates Using the cardinal temperature values of Baker and Reddy (2001), the number of days required to cumulate 200[degrees]C d beginning on DOY 100 was 22 d using HTU and 24 d using DTU, which differed significantly during the 43 yr period (Table 1).
During the next 18 months six hydel and four thermal units
will be commissioned.

The government on Tuesday announced revision in prices of domestically- produced natural gas from existing $ 5.05 ( ` 314.71) per million British thermal unit
to $ 4.66 ( ` 290.41) per million British thermal unit
based on gross calorific value ( GCV) basis, which would also result in reduction in the retail price of CNG and domestic piped natural gas ( PNG), the IGL said in a statement.
Sources said that ECC is likely to approve the ministry of petroleum summary regarding British Thermal Unit

so that supply for power generation can be increased.
A PLN director Ali Herman Ibrahim said PLN has reached an agreement on the gas price around US$ 2.7-US$2.9 per million British thermal unit
The thermal unit
size is very compact and does not require a refractory lining.
