Federal Energy Management Program
The mission of the Federal Energy Management Program is to
facilitate the Federal Government’s implementation of sound,
cost-effective energy management and investment practices to
enhance the Nation’s energy security and environmental
stewardship.
-
3 | FEDERAL ENERGY MANAGEMENT PROGRAM femp.energy.gov
Agenda
• Increased water rates
– Escalation rates
– Example
• Rate increases by region
• Rate increases by water source
• Rate increases by historical drought tendencies
-
4 | FEDERAL ENERGY MANAGEMENT PROGRAM femp.energy.gov
Study Cities
• Selection based on distance to Department of Energy
facilities
• Data from voluntary surveys to Ernst & Young, Raftelis
Financial Consultants, and American Water Works
Association
• Survey years: 1994, 2002, 2008
• Non-manufacturing and industrial rates analyzed

Drought Impacts
• Palmer Drought Severity Index
• 1895-1995 long range historical drought conditions
• 1996-2010 short range historical drought conditions
• 3 month forecast drought conditions
-
14 | FEDERAL ENERGY MANAGEMENT PROGRAM femp.energy.gov
Palmer Drought Severity Index
• Established to compare meteorological moisture conditions of
climate regions
• Positive Palmer numbers indicate excess moisture –
flooding
• Negative Palmer number indicate lack of moisture – drought
