Outside system battery limit costs

The common mistake observed is the capital cost estimate for a retrofit project being too low compared with reality. The main reason is that it does not include installation and the outside system battery limit (OSBL) cost, which could be as expensive as the inside system battery limit (ISBL) cost. This topic is discussed in Section 22.6. 

The investment cost will be given, indicated as ISBL (inside battery limit plant, laboratories, process control system, etc.), OSBL (outside battery limit) or infrastructure costs. It is expected that the OSBL costs for a micro structured reactor plant will be a minor issue as here mainly costs for housing, cooling facilities, etc., are included.
