A3.7 – Incremental cost of backup power for electric barrier – S3.5
Proposed standard S3.5 specifies that an operator must ensure that an electric barrier has a backup power source if it is the primary containment barrier for an enclosure. The one-off incremental cost of this proposed standard is estimated with the following assumptions:
-
One-off cost of installing a generator (diesel) estimated cost at $1,259.95141; and
-
5% of medium and small facilities not having backup power;
As shown in Table A3.12, the estimated one-off cost of backup power under proposed standard S3.5 would be $12,788 and would essentially entail one to two additional backup generators required for medium size facilities and about eight to nine additional backup generators required for small size facilities.

As shown in Table A3.13, the estimated one-off cost of backup power under proposed standard S3.5 over 10 years would be $11,952 in present value 2012-13 dollars with 85.96% of the cost incurred by medium size facilities.
