How our customers benefit from Cactos

"Cactos immediately impressed us with their strong expertise and high level of commitment. The collaboration has been smooth from the start."
Magnus Wikman
CEO, Wibax Energy
"With Cactos, we're able to lower the price of the electrical energy we buy, because the batteries are charged when electricity is cheap and that power is then used when buying electricity would be expensive. We also receive reductions on our basic and demand charges, because our consumption peaks aren't as high."
Reijo Alapuranen
Owner, YBT Oy
“With Cactos, we can shift our electricity consumption – storing energy during cheap hours and discharging it into the taxis when prices are high.”
Antti Lankila
IT Director, Menevä
