Energy demand management company KiWi Power has announced a 100 per cent success rate in accurately forecasting the three triad periods during the 2012/13 triad season. KiWi Power advised its customers to reduce or shift their power use when the UK’s demand for electricity was at its peak on these three specific half hourly periods, saving substantial sums on electricity bills, including one hospital that saved about £100,000.
The transmission network use of system charges, or ‘triads’, is the means by which industrial and commercial electricity consumers indirectly pay for the electricity transmission network in the UK. Triad charges are proportional to a business’s electricity demand at the three highest national system winter peaks.
Charges are regionally based and are expected to be as high as £34 for each kilowatt-hour of demand during the triads in some regions next year. And KiWi Power says that Triad charges can amount to over £50,000 of avoidable annual energy costs for each medium-large energy user.
Triad periods are not known in advance — but can be forecast, as they typically occur between 4.30pm and 6.30pm on weekdays during cold weather from November to February. These occurred on November 29 and December 12, 2012, and on January 16, 2013. On these days, the UK experienced severe weather, including temperatures as low as -20degC in some areas, along with hail and snowfall.
Cost to industry of the big freeze
January 2013 proved to be Britain’s snowiest month since December 2010, with late-January’s freeze costing up to £4 billion in damages to the economy. Yet despite the coldest February for 22 years, there were no triad periods in February.
“If a business is able to reduce its electricity demand during the triad periods, it can realise significantly reduced triad charges on its energy bill,” said Yoav Zingher, Director of KiWi Power. “We work closely with customers to develop a robust triad management strategy for the periods that have a high likelihood of being declared as triads for that year.”
By actively managing triad demand, KiWi Power enables its customers to benefit from reduced electricity charges. KiWi Power monitors the expected system demand through a number of sources and uses proprietary techniques to forecast potential triad events.
KiWi Power works with customers to alert them to triad events so that they have time to reduce or shift demand to some other period, or prepare for use standby generators. Triad management involves reducing consumption for around one hour during periods when peak demand is forecast. And KiWi Power can activate the triad strategy automatically on behalf of customers, or simply issue a triad forecast notification.
