Challenges.

Energy efficiency.

Catch residential energy waste before bills spike

Catch residential energy waste before bills spike

Residential buildings use more energy than necessary because heating, cooling, and insulation problems are found only after energy use rises.

Expose hidden electricity costs in small businesses

Expose hidden electricity costs in small businesses

Small businesses pay more for electricity because they cannot tell which equipment and processes use the most power.

Shift flexible electricity use off peak hours

Shift flexible electricity use off peak hours

Homes and businesses overload electricity networks during peak hours because they have limited ways to shift flexible uses to other hours.

Stop renewable electricity going unused on the grid

Stop renewable electricity going unused on the grid

Renewable electricity is wasted when electricity networks cannot deliver all the power generated where and when it is produced.

Compare energy use across multi-site businesses
