ELECTRIC ENERGY | Spring 2020 - 23

Batteries are a tool customers can use to shave their peak demand.
Although coming down in price, it is still tough to make battery economics
work. SRP is providing an incentive of up to $3,600 for those who qualify
and choose to use this technology. Most of the batteries being installed
under this program are paired with an inverter that gives a customer data
on when the battery is charging or discharging. It also allows for programing
control of these activities, and if coupled with solar, provides data on when
and how much solar is generating and the batteries are storing. Data can
be used with electric usage data provided by SRP's MyAccount to identify
patterns or usage peaks that can be reduced or "shaved" by the battery. This
method can be more complicated, but it may also allow for more opportunities for customers to make informed decisions on their use of electricity.

DATA IN ACTION
The graph above depicts the daily peak demand of a solar customer. As
illustrated on the left side, this customer was setting daily peaks of anywhere from 5 to 9.5 kW. On May 21, the customer met with SRP to review
the demand price plan and immediately they were able to make changes,
which resulted in a decrease in demand. The customer was introduced to
the MyAccount data available, and given some simple suggestions on how
to avoid reaching high-peak demands. Also important to note, this graph
shows that not only was the customer able to reduce their peak demand of
9.5 kW to less than 1 kW, but it was sustainable over several weeks.
Once customers invest in solar, it's crucial that they manage demand,
generation and usage to maximize the value of their systems. Once they
have the data they need in their hands, they can manage the data they
have and adapt their behavior.
Another example is a customer who was able to manage demand based
on accessible data from SRP. During the evening, on-peak hours, the account
was setting a peak demand of more than 9 kW, which greatly increased
the monthly bill. The home had a pool heater and a pool pump that were

programmed to turn on at around 8:30 p.m. just 30 minutes before the
on-peak pricing ended.
SRP was able to identify the pool equipment as being a large contributor to the household on-peak demand, which was easy to reprogram. By
changing the timer to power up the equipment just 30 minutes later, the
peak demand has been cut in half and decreased the bill significantly.
SRP also uses this data internally to provide customers valuable information by comparing usage history and patterns, and then alerting the
customer when it looks like usage is outside a normal range. The data
coming in from solar generation meters alerts SRP to notify customers,
often before they notice, that they are not generating.
Outage notifications are another way advanced meters are changing the
way we do business. These new meters send a last gasp message to SRP
when they lose power. This allows SRP to know exactly which homes are out
of power and send those customers a notification by email or text message.
Letting them know their power is out, sometimes before they even know, and
when SRP expects to restore power is a powerful customer service moment.

BACKED UP BY DATA
When SRP introduced a demand charge to rates for residential self-generators, we also offered an optional pilot demand rate for residential customers who did not have solar. We were able to study a full year of data
between solar and non-solar customers on rates with demand charges
and without demand.
In fact, the study found that solar customers, on rates with demand
charges and armed with the right data, decreased their monthly peak
usage by 11 percent more than solar customers without demand
charges. SRP will continue to analyze data and share what it knows
with customers.
Only time will tell if customers will continue to use data, but if it continues
to positively impact their bills, SRP believes they will.
