Abstract—We describe how 1-kWe combined heat and power (CHP) systems in the Korean residential sector affect the electrical grid. The maximum diffusible capacity of the CHP systems was determined based on user benefit, and these results were used to assess the domestic effect of CHP system diffusion. The maximum diffusible capacity was 840,000 kW, which should yield an annual reduction in fuel costs of 381 million USD, a 2.5-million-ton reduction in equivalent CO2 emissions, and a reduction in the peak demand for electricity of 0.84 GW. The Korean government has recently announced its intention to increase the use of distributed power sources; on-site 1-kWe CHP systems are expected to be an important aspect of this.

Index Terms—cogeneration, national benefit, distributed power source
