Electricity bill reduction
Lowering your electricity bill is possible when it is done with engineering.
How a medium-voltage electricity bill breaks down
Many companies today set out to save energy, but few achieve a real, lasting impact on their electricity bill. Savings depend not only on installing equipment, but on understanding how energy is used and where excess costs arise.
At Dacast, we help companies reduce their electricity bills by targeting the two components that truly matter: energy and demand.
More than a third of the bill is usually demand, not energy.

Three consumption profiles, three solutions
Profile 02
Pronounced peaks
High demand, with machinery start-ups that drive up maximum demand.
- Solution

Frequently asked questions
Why does demand weigh so much on a medium-voltage electricity bill?
On a typical medium-voltage bill, peak-hour demand accounts for 36% of the subtotal, off-peak energy for 47%, peak-hour energy for 12% and fixed charges for 5%. That is why Soluciones Dacast targets the two components that truly matter: energy and demand.
Which solution fits each consumption profile?
For daytime operations, solar photovoltaic (PV) for maximum self-consumption. For demand with pronounced peaks from machinery start-ups, a hybrid PV + BESS system for peak shaving and self-consumption. For steady, around-the-clock consumption, storage only (BESS) for peak shaving.
What is the process to reduce an electricity bill?
Four steps: a review of twelve months of bills to break down energy and demand; on-site measurement with a power analyzer to capture the real load curve; design and proposal with sizing, investment and estimated payback; and execution with detailed engineering, installation, certified commissioning and follow-up monitoring.
What is a BESS?
BESS stands for Battery Energy Storage System. Soluciones Dacast uses it on its own or alongside solar panels, for profiles with pronounced peaks or continuous operation, to shave maximum demand (peak shaving).
