The construction costs of the ESS facility amount to 1552 Million € at 2000 prices, including not only capital investments for all components necessary for the ESS but also the 3300 years of manpower (in-house plus subcontracted staff) required during construction. A contingency of 15 % is added to the calculated cost.
ESS will be a user facility operating at least 44 instruments in User Service Mode (USM) for 5.500 hours per year. The operational budget amounts to 142 Million € at 2000 prices. This budget includes completion of the instrument suite and later the systematic replacement of components and instruments at a rate of 3 per year.
The break down of construction costs into main subsystems shows the equal importance of conventional facilities 35% on the left of the picture and accelator systems (linac 28 % at bottom+ rings 6% + beam transfer 1%), that is to say 35 % each.
The remaining 30% are for targets, instruments, control and management.
