A subsequent APWG study in 200529 found that many older power plants in the Asia-Pacific
region were operating well below their design efficiency. However, the study found that replacing
the older CFPPs with new power plants was not practical because the expenditure for a new plant
could not be justified by the improved performance. Instead, efficiency and operational
improvements were seen as a possible alternative considering a range of equipment upgrades and
refurbishment options to various CFPP systems
