5. Systems Solutions Water-Energy Nexus,
The IOU’s are directed to evaluate and implement EE programs with more societal benefits –
Save Water-Save Energy!
Specifically, we are currently evaluating
Leak Loss Prevention
System pressure control
State of the Art -Irrigation Controller’s
Well Rehabilitation
If you are pumping water using Natural Gas Engines, and the embedded energy in the water savings can be attributed to your Natural Gas usage, you may qualify for energy saving incentives

6. Compiled from data in CPUC Study2
Just 7 Water & Wastewater Agencies Alone Contributed to 93MW of SCE’s peak demand in 2008
The seven agencies contributed 93 MW, the coincident water related demand for all the agencies in Southern california may well exceed 1,000 MW.
Water & wastewater agencies have more flexibility to change the amount, time and place of their electric use
Reducing on-peak demand could eliminate need for power plants that are only used about hours per year
New, efficient gas engines would help electric reliability and accelerate shutdown of old, inefficient fossil fuel power plants, reducing GHGs.
Not surprisingly, most groundwater pumping occurs during hot summer months in which electric demand is at it’s highest.

Operating Cost Analysis
We will model your electric motor costs vs natural gas engine costs, to enable you to evaluate the Time of Use cost differential

10. Natural Gas Engine-Driven, Water Pumping Systems
Financial Incentives
Based on a 300 HP engine running about 2000 Estimated Full Load Hours (EFLH), the added load is 50,000 therms
The Gas Company may provide to qualified projects, line allowances, which can be used to pay for new gas line services
There are incentives available to offset the equipment installation costs, under Rule 38
The customer must commit to this added usage for a five-year contract term.
*If usage falls below contracted amount the customer will face an annual true up of the delivery charge to the contracted amount
