Opole Power Plant 1997-1998	Analysis researching the possibilities of introducing technical and organisational changes at Opole Power Plant, to improve and rationalise its operation. The coal﷓fired power plant consists of 4 equal units with a capacity of approx. 350 MWe and is one of Poland's most modern power plants. Technical benchmarking with Danish power plants.
Bełchatów II Power Plant Management 1997	Independent expert opinion for the study on super critical parameters and optimisation of unit capacity for Bełchatów II.
Kostrzyn Paper MillVattenfall Poland Sp. z o.o. 1997	Feasibility study covering rehabilitation of an industrial CHP plant at Kostrzyn Paper Mill. The study covered analysis of heat and power demand and a technical assessment of the existing equipment. The alternatives analysed included combined cycle alternative consisting of gas turbines and waste heat recovery boilers with supplementary firing, each with a capacity of 70 ton/h steam. Preparation of full tender documentation for modernisation of the existing and erection of two new gas fired boilers. Tendering procedure and selection of Contractor.
Elektrociepłownia Zielona Góra S.A.Danish Energy AgencyPartner: DPC. 1995 - 1998	Preliminary feasibility study for modernisation Zielona Góra CHP Plant. The project was grant supported by the Danish Energy Agency and co-financed by EC Zielona Góra. The project included determining the heat, steam and electricity demand. A number of plant concepts were analysed such as biomass fired boiler and gas fired combined cycle plants. The use of domestic low calorific gas was analysed. A combined cycle plant with a capacity on 100 MWe based on domestic gas was analysed in details covering technical, economic as well as financial matters including defining security package covering off-take contracts.
Zespół Elektrowni Ostrołęka 1994 - 1995	Feasibility study for modernisation of Ostrołęka A CHP plant. The following alternatives were investigated: rehabilitation of existing CHP, district heating extraction from power plant Ostrołęka B, new coal fired CFB CHP, new combined cycle gas fired CHP. The coal fired CFB and the gas fired Combined Cycle plant were selected as the most attractive solutions and detailed financial analysis were prepared for these alternatives.
Zespół Elektrowni Ostrołęka 1995-1995	Pre-feasibility study of bark firing at Ostrołęka A CHP Plant. The following alternatives were investigated: new multifuel CFB boiler, additional furnace to the existing boilers, new Bubbling Fluidized Bed (BFB) boiler, retrofit of the existing PC boiler to BFB bark firing boiler. The latter alternative was implemented. ELSAMPROJEKT prepared investment package, and long-term fuel supply contract, implementation study, detailed tender specification, and contract with main contractor.
Polskie Sieci Elektroenergetyczne S.A.Danish Environmental Protection Agency 1993-1994	Technical Assistance to Polish Power Grid Company (PSE) Preparation of a study "Potential of priority and CHP Development in Poland" for the Polskie Sieci Elektroenergetyczne (Polish Power Grid Company). In 1992 PSE agreed with the World Bank to initiate a least cost plan for the development and rehabilitation of the Polish power plants. Part of this study is an analysis of the potential for development of cogeneration on the basis of existing and new power plants.
