The settlement challenge facing suppliers
Energy suppliers today are obliged to procure electricity from the wholesale market at 30 minute intervals. However, most UK consumers continue to be settled on a ‘non-half-hourly’ basis using daily reads or usage estimates. The result is an imbalance between supply and demand, which severely affects the bottom line in today’s volatile energy markets — the EHHS Service from SMS tackles this head-on.

Ask us for a free review of your portfolio, and we will show you the savings in monetary terms and the new opportunities the service can roll out to your customers. 

The solution
Smart meters, which suppliers are mandated to roll out by 2025, can record the amount of energy consumed within every half hour of the day. This provides suppliers with a golden opportunity to tackle these challenges head on.

  • Make the settlement process more accurate and timely
  • Generate cash
  • Enable new products, smart tariffs, and innovative services tailored to customers’ actual usage.

Through smart meters, half hourly settlement has the ability not just to significantly lower the cost to serve, but can also deliver positive outcomes for consumers through lower bills, reduced environmental impacts, and an overall better customer experience.

Get ahead of the market: act before Ofgem's mandate

To encourage the transition to a smarter, greener energy system, by 2025 Ofgem’s market-wide reform means energy suppliers will be mandated to offer their smart meter customers half hourly settlement. Suppliers now have a window of opportunity to gain an immediate advantage and get ahead of the market with Elective Half Hourly Settlement.
