Your energy
bill is not just how much energy you use but the “rate” at which it is used and
also “when” you use it: a combination of consumption (energy), demand (power)
and Time-of-Use. Demand is defined by Southern California Edison (SCE) as: “The
measure of how much electricity is used at a single point in time” and is
charged by kW (kilo-watts) vs energy use which is charged by kWh (kilo-watt
hours). The utility infrastructure (“the grid”) must be prepared to provide a
certain level of power demand, varying on the time of day – PEAK demand occurring
around early evening (4pm-9pm). The Utility collects Demand Charges to cover
the cost of Grid Upgrades necessary to be capable of providing power up to the level
of Peak Demand. Generation and Distribution of Power requires sufficient powerlines,
transformers, substation facilities, but most expensive of all Power Plants!
There are two
different demand charges billed by the utility: Facilities Demand and
Time-Related Demand. According to SCE
website, “Facilities Demand Charges apply at all times throughout the
year, calculated per kilowatt (kW) according to your highest recorded demand
during each billing cycle—no matter what season, day of week, or time of day,
while Time-Related Demand Charges only
apply during the summer season (June 1 through September 30), when demand
reaches its peak and costs are highest. Time-Related Demand Charges are
assessed each month during On-Peak hours & also during Mid-Peak hours. Time-Related
charges are in addition to and separate from a Facilities-Related Demand
Charge.”
Energy Storage for Lower Grid Demands
= Happy Solar Consumers!
Energy bills
come with so many charges, so what do we do?
ADD BATTERIES, of course! Solar combined with Storage allows for saving
on not just Energy Consumption costs, but also Power Demand charges – this
means Overall Bill is able to be reduced to lowest possible result. Solar
generation generally happens during hours that fall within what is called “Off-Peak
TOU rate schedule” (8am-4pm) times when value of energy is at its lowest. During
the evening times, PV systems are not producing energy and ‘coincidently’ lines
up with “On-Peak TOU schedule” (4pm-9pm) – when energy and power costs are at
their highest.
With
Batteries, energy produced during the day that isn’t immediately consumed can
get stored for usage later in the evening to avoid (high cost energy) imports
from “The Grid” and reduce Peak Power level that “The Grid” must provide (reduce
demand charges). Good for everyone!
Value of Solar
Energy MAXIMIZED with addition of BATTERIES!
