Delivering outcomes to support a more cost-effective electricity industry

Climate change presents the world with a challenge to urgently protect our planet, our economy and our populations.

The UK has set a world-leading net zero target, the first major economy to do so. Having set the target, the focus turns to delivering against that target. In the Energy White Paper ‘Powering our Net Zero Future‘ the government has set out an ambitious programme to build a fairer greener energy system.

Market-wide Half-Hourly Settlement (MHHS) is a key enabler of the flexibility to support the transition to Net Zero. The MHHS Programme will contribute to a more cost-effective electricity system, encouraging more flexible use of energy and helping consumers lower their bills.

Introduction from MHHS Programme SRO

Market-wide Half-Hourly Settlement (MHHS) reform will see the electricity industry working together in a significant move forward in how electricity is used and accounted for.

The MHHS Programme is an industry first, in that Ofgem has placed responsibility on the industry to deliver the Programme and made Elexon the Senior Responsible Owner (SRO) of the Programme.
