Donbasenergo (DOEN) plans to complete the rebuilding the #4 power unit at its Starobeshev TPP by December 20, Ukrainian News reported on Friday. The company had previously planned to complete the work by August. Yegor Samusenko: The #4 power unit at the Starobeshev TPP is designed to work with circulated fluidized bed (CFB) technology, which allows for up to 20% savings in costs. However, being the first CFB-unit in Ukraine, there has been a long story to its launch: it has already been in testing mode twice, four years ago and one year ago, and failed both times to make the transition to normal operating mode. We are also skeptical this year’s launch will be successful.
