Businesses in the Midlands could be losing a fortune through extra winter energy charges they could avoid, according to PCMG.
PCMG, which specialises in recovering energy costs for businesses, has seen companies in the Midlands spending up to seven-figure sums on Transmission Network Use of System charges, which have gone up by 136% and 125% with suppliers East Midlands Electricity and Midlands Electricity respectively since 2010.
Transmission Network Use of System charges cover the cost of transporting electricity long distances from power stations to regional networks. They make up approximately 6% of the total energy bill for big businesses and much more in some cases.
Will Stephens, Senior Energy Analyst at PCMG, said: “TNUoS charges have increased astronomically in the last 15 years. For high energy users, from manufacturing firms to cold storage companies, or just those with multiple sites, it can be a huge cost, representing a big chunk of the bill.”
The cost is worked out by looking at usage when demand across the system is at its highest between November and the end of February.
Will said: “TNUoS charges are based on looking at the three peak half hour periods, known as Triads, of energy use from November to the end of February and then the charge for each business is based on those periods.
“Typically Triad periods occur most often in December and January, between 17:00 and 18:30 when the tea time rush combines with the commercial demand. The measures have to be 10 days apart and often weather and temperature can play a part.”
According to PCMG, businesses can reduce TNUoS costs by reviewing when energy is used.
“We’ve worked with clients on electricity management to radically reduce or even bring TNUoS to a zero cost,” Will said.
“This can be done through predicting when the Triad periods are likely to fall and then looking at power usage during these peak periods, shutting down processes in the peak energy use period.
“Key to this is having access to real time data showing what you use and then putting in place an effective energy management process, even shift to onsite generation if you can, to ensure you aren’t putting load on the system during a peak period.”
