Exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant
This paper presents exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant using specific exergy costing (SPECO) methodology. Cost–balance and auxiliary equations are developed and solved. The results indicate that in the topping cycle, the boiler and the turbine contribute maximum to the formation of product cost. High value of exergoeconomic factor for the boiler ...

A real options approach to investing in the first nuclear power plant under cost uncertainty: comparison with natural gas power plant for the Tunisian case
This paper uses a real options approach to present a method for evaluating the first Nuclear Power Plant (NPP) investment in Tunisia in 2020. The evaluating model integrates the value of real options: option to wait in the standard discount cash flow analysis. According to the IAEA (2007), starting the first stage of a nuclear power programme makes it possible to construct the first NPP in second ...

Energy efficiency: What are the laggards thinking?
Why do some states avoid creating policies that encourage consumers and businesses to save energy? What’s the psychology of the laggards? A new report by the American Council for an Energy Efficiency Economy sheds some insight as it examines the states that consistently fall behind in the organization’s annual energy efficiency ranking. The bottom states are: Alabama, Kansas, ...

Understanding fuel switching under the EU ETS
Since the creation of the European Union Emission Trading Scheme (EU ETS), European power producers have monitored carbon emissions resulting from the composition of their production. Fuel switching is the main short–term abatement measure under the EU ETS. It consists in substituting combined cycle gas turbines (CCGTs) for hard–coal plants in off–peak power generation. Thereby coal plants run ...

Solarthermal parabolic trough power plants with integrated storage capacity
Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...

Techno-economic evaluation of revamping of coal-fired power plants in India
A techno-economic feasibility study has been conducted to investigate the revamping of two 32 MWe Pulverised-Coal (PC) boilers with a number of firing options. The options investigated were: (1) conventional PC revamping, (2) replacement with a new PC boiler, (3) PC to Circulating Fluidised Bed (CFB) revamping, (4) replacement with a new CFB boiler, and (5) Bubbling Fluidised Bed (BFB) revamping. ...

Economics of tiny thermal power plants
Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

The natural gas revolution: Good or bad for energy efficiency?
If there were an equivalent in the energy industry to Time Magazine’s Person of the Year, natural gas would be this year’s winner. The dramatic rise in natural gas supply, and fall in price, has reconfigured the energy scene in the United States, suddenly creating a bounty of domestic energy, driving down wholesale power prices and speeding retirement of polluting coal-fired plants. ...
