Questions & Answers
What is an Energy Efficiency Program?
National Grid offers financial incentives to customers who purchase
and install qualified energy efficiency equipment that meets
established program requirements for high efficient energy saving
equipment.
Eligible customers must be located in a National Grid service
territory in Massachusetts, New York or Rhode Island. Customers
who receive a National Grid electric or gas bill are qualified to
participate in a variety of programs.
Participants receive a financial incentive that assists the customer
in recovering the higher incremental cost for purchasing more
efficient products.
All customers contribute to this Energy Efficiency fund through a
surcharge on their utility bill.

Why Do Energy Efficiency?
Increases value of your property
Improve manufacturing efficiencies
Lowers energy bills
Reduces maintenance costs
Creates a better work environment for employees
Enhances a building or company image
Increased reliability of equipment
21
Qualifying a Large
Commercial / Industrial Client
Is the customer a National Grid commercial/industrial account?
Is the product being installed new?
Only new products qualify.
Does the product meet all qualifying conditions?
Delta Electro Power (Delta) will coordinate with your National Grid
account representative to determine if products qualify, and to
make sure proper application is completed.
Delta will assist to complete application in its entirety and submit all
relevant documentation as listed on the application.
Upon application approval, National Grid will provide a commitment
letter for the amount of incentive and any qualifying conditions that
need to be met to be qualified.
22
Variable Speed Drives Audit & Review
Variable Speed Drives eliminate the losses and costs of throttling
devices, allowing for reduced power consumption and improved
energy factor.
Audit/Application Process:
Delta performs site review to assess Variable Speed Drive applications
that do not currently exist
National Grid reviews audit and verifies that motor or replacement motor
and drives meet program requirements
Hours of operation meet minimum requirements (>2000 hours)
National Grid calculates performance and savings (before offering
customer commitment)

Compressed Air Leak Survey /
Supply-Side Audit
An air leak survey will establish the size of a leak and the amount of
benefit which can be realized by repairing the leak. Repairing leaks
will allow customers to achieve lower operating costs. Costs will be
shared for the repair.
Audit/Air Leak Survey Requirements and steps for authorization:
Delta/Atlas Copco submits a proposal for air leak study to National Grid
Delta details scope of work and type of metering equipment to perform
evaluation.
Delta provides a written report identifying system leaks and benefits that
can be realized by repairing leaks.
