Each invoice consists of a combination of contractual and regulated charges so simply working out the real cost is difficult. e21 EnergyPlus simplifies this process.

Check the figures given to you by your supplier with actual rates generated from your own contract together with the appropriate regulated and associated charges sourced directly.


Generate a range of graphs to assist you in detecting irregularities in your electricity bill over one or many sites.

Because emissions are calculated for each site from billed consumption data, there is essentially a double entry validation of emissions data as part of cost verification. e21 EnergyPlus can then report emissions by period and by site groups.
