the Database of State Incentives for Renewables & Efficiency
(DSIRE). This comprehensive source includes information on state,
local, utility, and federal incentives that promote renewable energy
and energy efficiency. Be aware that most incentive programs have
detailed application procedures and require project prenotification.
So, the next step, after finding an organization offering a rebate or
incentive, is to contact it to learn about its requirements.
2. Assess energy usage: Many organizations see only a monthly power
bill of their total consumption. Consequently, those in charge rarely
see the impact of their equipment decisions and cannot prove their
changes saved energy. To participate in a rebate program, you need
to determine the power usage for the total data center or the systems
or hardware you target to improve. Specific measurements might
include chillers, air handling units (HVAC), and IT equipment such
as servers and storage arrays. Measurement methods depend on your
facility’s power monitoring capabilities and the recommendations of
the utility or state energy-efficiency team. The best measurements
include both peak and seasonal events to better comprehend the
ptg
energy provisioning required.
3. Take advantage of project design and energy-efficiency teams:
Many energy-efficiency groups can provide project support to help
maximize energy-efficiency gains, cost-savings, and incentives.
Partnering with your utility can help ensure you meet all the pro-
gram requirements.
4. Calculate energy savings: You probably need to provide direct
measurements of your power usage before and after your project is
implemented or perform other required calculations of the energy-
savings benefits. Your utility or efficiency program can help you
with this requirement.
5. Submit incentive or rebate payment application: Programs gener-
ally require proof that changes have been done and energy is being
saved. You can reap additional goodwill benefits from your project
by publicizing your energy-efficiency efforts.
