Webinar: kW Incentives for Peak Demand Reductions
Slide 1: kW Incentives for Peak Demand Reductions
Script: This training session is brought to you by Southern California Edison (SCE).
Content: Presented by CLEAResult
Slide 2: Welcome! Meet your hosts
Script: Today’s training is presented by CLEAResult, a third party consulting firm.
My name is Eric Mullendore and I’ll be your presenter today. Joining me on the chat function in WebEx
is my colleague, Bobbi Brunkalla.
For the past two years, we’ve both been providing technical support services to SCE’s Customer’s
Authorized Agents. I’ll be providing some contact information at the end of the session in case you are
interested in taking advantage of these services.
After today’s webinar we will provide a copy of the presentation to attendees.
All phones are muted so please use the chat function to communicate and Bobbi will respond.

Slide 4: Learning Objectives
Script: Every training we do, we present the learning objectives within the first couple slides. Hopefully
after the presentation you’ll be able to:
Recall the incentive rate for kW in Customized Solutions
Define peak demand reduction and kW
Assess solutions for potential kW impacts
Content: At the end of this session, you will be able to:
•
Recall the incentive rate for kW in Customized Solutions
•
Define kW and peak demand reduction
•
Identify solutions with relatively high kW impacts
Slide 5: Defining Demand
Slide 6: New Incentive Rate
Content: Effective 7/1/2014, the incentive rate for kW in Customized Solutions has increased 50% to
$150 / kW.

rate.
Slide 7: kW vs. kWh
Script: For illustration purposes only. Graph not based on actual metered data.
Content: Average Power Demand = 1 kW
Time Period = 9 hours
Total Energy Consumption = 9 kWh
Images: Clip art of an engine. Graph of kW over time showing varying power demand and a flat line to
show average demand.
Slide 8: Comparing Customer and Utility Peak
Script: In most commercial rate schedules, customers pay demand charges based on the demand during
the highest 15-min interval. The graph shows a week’s worth of data for a customer with typical 7am5pm, Mon-Fri operating hours. You can readily see that the first two days are on the weekend and that
at night the site is drawing just under 100 kW. Equipment that only operates during these hours is not
contributing to the customer’s peak demand of 575 kW, which occurs on Tuesday afternoon at 3pm. For
many customers this peak will be driven by a combination of high occupancy and high outside air
temperatures. Not all customers are the same though so it’s important to understand operational hours
of the site’s major energy consuming systems to understand how an energy efficiency project will
impact their demand charges.
The second graph might take a second to understand. On the Y-axis we see the total demand on the
California electric grid, measured in megawatts. On the X-axis, we see the % of the hours in the year that
the system had a demand of at least the value shown on the Y-axis. The key take way here is that the
grid has to have a lot of extra capacity to serve the high demand that occurs on a relatively few number
of hours. In fact in 2012, the grid required 6,000 MW of extra capacity for only 150 hours (that’s 15% of
capacity being used for less than 2% of the year). These high demand hours are the result of the high
aggregate demand of the customer base so it makes sense that they generally occur around the same
time as most customers experience high demand, hot weekday afternoons. The last incremental
capacity required to meet the grid’s peak load/demand tends to come from the most expensive and
polluting generating resources that the system operator has available. These last facts explain why SCE
and its regulators are so interested in demand reductions during hot summer weekday afternoons.
Graphs are for illustration purposes only and are not based on actual metered data.
Image: Two graphs, one of business customer demand and CAISO system load duration curve in 2012.
The first graph shows the customer peak demand at 575 kW and the second one shows electric grid
used last 15% of total capacity for only 150 hours.
Slide 9: DEER Peak Demand Windows
Script: SCE requires use of predefined peak demand periods to calculate demand reductions. The
calculation should assess the average demand impact during this demand period, which is from 2p-5p
on three consecutive business days. The exact date range varies by climate zone. You can determine the
climate zone for your project using the Excel file located:
http://www.energy.ca.gov/maps/renewable/Climate_Zones_Zipcode.xlsx. This information can also be
found on the resources tab of the lighting calculator.

Slide 10: Example Projects
Slide 11: Lighting
Script: Graphs are for illustration purposes only and are not based on actual metered data.
•
Exterior lighting is not on so does not reduce demand during peak demand period. All
energy savings occur at night.
•
Most interior lighting in a business environment is on during business hours so there is
likely a significant demand reduction achievable by improving luminaire efficiency. One
must consider the impact of controls on the baseline though. Daylighting controls and
occupancy sensors are likely to reduce demand impact as well as total energy savings
from luminaire efficiency.
•
Daylighting controls can also usually be expected to achieve a significant portion of max
demand reduction during the peak demand period.
It’s important to note that the Y-axis is a % of the max kW reduction achievable by each solution code.
The maximum demand reduction achievable by each solution will vary considerably from site to site.

Slide 12: HVAC
Script: Graphs are for illustration purposes only and are not based on actual metered data.
•
Night setback will not reduce demand reduction during peak demand period. This is a
good example of a solution that includes a load shifting component. The HVAC system
will see increased savings in the morning as it brings the building back to occupied
setpoints.
•
Supply air fans generally operate continuously during occupied periods, thus improving
efficiency of the fans will reduce demand during the utility peak demand as long as the
building is occupied during this timeframe (for example, many schools my be
unoccupied in summer)
•
Evaporative pre-cooling is a great example of a solution that aligns with SCE’s peak
demand goals. These systems are often activated only when it is hottest outside and so
save the most energy on hot summer afternoons.

Slide 13: Refrigeration
Script: Graphs are for illustration purposes only and are not based on actual metered data.
•
Stand-alone condensing units, like are often used at restaurants or convenience store
walk-ins, run intermittently or cycle throughout the day and night. The demand
calculation will have to consider the average savings over the peak demand period, not
just the highest reduction in demand.
•
Demand defrost controls are increasingly popular in the supermarket sector. While they
present the opportunity to reduce annual energy consumption, they are unlikely to have
a significant impact on demand unless the site has scheduled one of its defrost cycles
during the demand period.
