Shifting consumption away from peak hours could save your clients thousands

Red band rates - those peak evening hours - cost significantly more than Amber or Green periods. How much more depends on the DNO region, but the difference can be substantial. For larger sites already on half-hourly metering, the opportunity is there but hard to quantify. And with MHHS rolling out, smaller sites are now seeing their actual consumption patterns for the first time.

Risk: Without modelling the savings, it's hard to build the business case for operational changes, battery storage, or smart controls.

Quick Answers

What are Red, Amber, and Green time bands?

DUoS charges vary by time of day. Red periods are peak times with highest rates (typically 4-7pm weekdays). Amber periods are shoulder times with moderate rates. Green periods are off-peak with the lowest rates (typically overnight and weekends). Exact times vary by DNO region.
