Power Purchase Agreements (PPAs) + Meter Aggregation
for Water Districts
Meter Aggregation dramatically improves PPA savings
and deployment flexibility for water districts.
Thanks to PPAs powered by Meter Aggregation, solar power is
no longer an overpriced luxury but the best long-term energy
value for water districts and other tax-exempt/public entities

What’s The Big
Deal With Meter
Aggregation?
Meter Aggregation—also called Net Energy
Metering Aggregation (NEMA) or Aggregated
Net Metering (ANM)—makes it possible to tie all
your operations and facilities into a single solar
array, increasing efficiency and PPA savings.
Before March, 2014, you had to build a dedicated
solar array for each meter you wanted to offset. So
10 pumps with 10 meters would have required 10
separate solar arrays. This increased costs, reduced
flexibility, and created long-term uncertainty...
especially for water districts with multiple service
points dispersed over a wide area. It also made it
challenging to offer compelling PPA savings.
Remotely located
pumping stations
and groundwater
wells, PLUS...
Dispersed holding
tanks, towers and
reservoirs, PLUS...
Large loads at water
treatment and
filtration facilities,
PLUS...
Meter Aggregation changes all that. Today,
a single solar array is now allowed to offset
multiple meters/service points.
So those 10 pumps mentioned above can all be tied
into just one solar array. This makes it easy to shift
offsets as electrical usage changes and maximize
solar ROI. Add in the efficiencies from engineering,
permitting, procuring, and constructing a single
solar array versus multiple solar arrays, and CalCom
Solar can confidently deliver much higher PPA
savings than previously possible.
What’s more, Meter Aggregation greatly increases
installation options. No need to locate a solar array
near a meter/service point. You can deploy virtually
anywhere...even on different parcels separated by
roads (as long as they are contiguous).
Booster pumps
spread throughout
your distribution
system, PLUS...
Solar arrays
can be installed
virtually anywhere
With Meter Aggregation, a single, centralized solar array can offset multiple
meters and deliver higher PPA savings...

6% each year from 2012 -2014) vs. a 20-year PPA arrangement @ 10 cents per kWh, including a solar array
production degradation of 0.5% per year.

What is a PPA?
A Power Purchase Agreement
(PPA) is a financial arrangement
between you—the Host
Customer—and Investors.
It is made possible by the
collaborative, integrated effort
of several players, all coordinated
by CalCom Solar.
Host Customer: you authorize a
solar panel system to be installed
on your premises and agree to
buy electricity for 20-25 years at a
fixed rate. There are no upfront or
fixed costs and you pay only for
the electricity you use.

How Does a PPA
Work?
As a solar PPA host customer, you do
NOT own or maintain the solar power
system at your site. It is owned by
investors.
Investor re-sells
kilowatt-hour credits
at a discount to Host
Customer, who redeems
the credits to “pay” for
electricity from grid
kW
Host Customer
h
Utility buys excess
electricity generated
by solar power system,
while continuing to
supply Host Customer
with electricity from the
grid for times when solar
isn’t producing sufficient
electricity (e.g., at night)
Investor
kW
h
Utility delivers
kilowatt-hour
credits to Investor
in compensation for
electricity received
from solar power
system at Host
Customer site
Utility
Power generated in excess of your
usage is bought by PG&E/SCE. This
solar-generated power earns kilowatthour (kWh) credits for the PPA investors
at a retail (not wholesale) rate. Thus,
they are able to discount the kWh
credits when they sell them to you for
cash. In turn, you use these kWh credits
to pay for any electricity you continue
to consume from the grid, for example,
during the night when the solar array
isn’t generating electricity.
These kWh credits always buy the same
amount of electricity on your bill. It’s
the same effect as Forever postage
stamps—both are valid no matter
how much rates go up. The bottom
line: large, long-term savings for you.
