# §990.180. Utilities expense level: Computation of the rolling base consumption level.

- (a) **General.**
  - (1) The rolling base consumption level (RBCL) shall be equal to the average of yearly consumption levels for the 36-month period ending on the June 30th that is 18 months prior to the first day of the applicable funding period.
  - (2) The yearly consumption level is the actual amount of each utility consumed during a 12-month period ending June 30th. For example, for the funding period January 1, 2006, through December 31, 2006, the RBCL will be the average of the following yearly consumption levels:
    - (i) **Year 1 = July 1, 2001, through June 30, 2002.**
    - (ii) **Year 2 = July 1, 2002, through June 30, 2003.**
    - (iii) **Year 3 = July 1, 2003, through June 30, 2004.**
- (b) **Distortions to rolling base consumption level.** The PHA shall have its RBCL determined so as not to distort the rolling base period in accordance with a method prescribed by HUD if:
  - (1) A project has not been in operation during at least 12 months of the rolling base period;
  - (2) A project enters or exits management after the rolling base period and prior to the end of the applicable funding period; or
  - (3) A project has experienced a conversion from one energy source to another, switched from PHA-supplied to resident-purchased utilities during or after the rolling base period, or for any other reason that would cause the RBCL not to be comparable to the current year's consumption level.
- (c) **Financial incentives.** The three-year rolling base for all relevant utilities will be adjusted to reflect any financial incentives to the PHA to reduce consumption as described in [§ 990.185](/cfr/24/990.185.md).
