Conventional Power Production
Oil and coal, in particular, have always been considerably cheaper energy sources, while natural gas is the relatively cleaner choice.
The Clean Development Mechanism provides an economic incentive to switching from oil and coal to natural gas or biofuels, that aims at reducing the emission of greenhouse gasses.
But there are even more efficient ways of reducing emissions from conventional power production. Energy efficiency is considered one of the most accessible and cost-effective opportunities to mitigate climate change. The IPCC and the IEA have shown that energy efficiency could be one of the key mitigation technologies to achieve the necessary short term emissions reductions.
There are obvious opportunities to utilise waste heat from power production for the supply of heat through the establishment of a district heating system – or cooling through a district cooling system. New power stations may be designed for cogeneration, which can typically improve efficiencies from approximately 40% to 80%, or more. Technologies employed in CDM projects are presented in the following sectors:
- Energy Efficiency Improvements
- Fuel Shift
- New Systems
Título de proyecto: Construction of additional cooling tower cells at AES Lal Pir (Pvt.) Limited
The purpose of the project is to utilise the latest technology to improve the heat rate of the power plants, which entails construction of an additional cooling tower cell for each unit’s cooling tower. A better heat rate will lower CO2 emissions by reducing in the quantity of fuel required to generate electricity. The efficiency improvement program under the project activity consists of the construction of additional cooling tower cells, installation of advanced technology and mechanical works including piping, connections, etc.
Project CO2 reduction over a crediting period of 7 years: 78,252 tCO2e (per/year: 11,179)
