After the 2011 Great East Japan Earthquake, a business continuity planning, i.e., BCP, in a disaster case is attracting attentions in Japan. However, when a customer, i.e. a building owner actually would like to introduce energy generation devices such as a cogeneration equipment, there is no guideline to decide suitable device capacity based on the evaluation of economic efficiency and BCP as well as energy saving performance. This study proposes a method to optimize a plan for installing cogeneration equipment considering BCP under disaster risks simultaneously. We develop a simulation tool to decide an optimized planning of energy-generation equipment configuration. With this simulation tool, we performed case studies for different business cases such as a hospital and a hotel. The simulation results showed that the optimized installing plan can be an over-specification of equipment configuration under the assumption of disaster risks, which is never chosen under conventional definition. Then, we examined the economic performance of an energy generation equipment configuration by calculating a net present value from the viewpoint of BCP. This examination can give judgments of investment-return possibility and suitable subsidy price.
