I'd guess that they used to have very good discounted contracts but are not able to renew them anymore.
The cost they charge also includes the cooling, so you could see it as for example 30c/kWh for power, 15c/kWh for cooling to compare it to a consumer contract. Maybe they have published their ratio of that split "on average" before.
