How MHHS Data enables UK Decarbonisation

The UK is charging towards its ambitious target of 95% clean electricity by 2030 but there’s a challenge.

How do you optimise consumption when electricity comes from renewable sources you can’t predict?

The answer lies in new MHHS data.

It’s the data revolution critical to decarbonising the UK and reaching Net Zero.

Why MHHS Data Matters for Decarbonisation.

Traditional fossil fuel generation is controllable. Coal and gas plants can adjust output to meet demand.

That made it possible to run the market on estimated usage and monthly billing.

For decades, the UK used Non-Half Hourly metering, with readings taken every 14 months.

But renewable energy changes everything.

With the Clean Power 2030 Action Plan pushing for more offshore wind, onshore wind, and solar, the old system can’t keep up.

These renewable sources are variable and harder to predict.

That’s where MHHS data becomes critical.

MHHS: The Market Mechanism Behind Net Zero

Market-wide Half-Hourly Settlement changes how electricity is measured and billed.

It uses actual Half Hourly data from remotely read meters instead of estimates.

But the real power of MHHS data lies in how it supports decarbonisation.

1. MHHS Data Enables Renewable Integration

MHHS data is a vital enabler of the UK’s transition to a low-carbon energy system.

By delivering accurate, Half Hourly electricity data from consumers, it allows the grid to match supply and demand more precisely in real time.

This level of detail gives grid operators and energy providers clear insights into when and where electricity is being consumed.

As a result, when renewable energy—such as wind or solar—is available, the system can respond faster and more efficiently.

With access to MHHS data, the energy sector can:

• Better predict demand patterns
• Accommodate variable generation
• Reduce reliance on backup power sources

2. MHHS Data Unlocks Flexibility and Demand Response

MHHS data enables large-scale Demand Side Response (DSR) and flexibility.

By providing detailed consumption data, new price incentives can encourage consumers to respond dynamically.

This flexibility is crucial for grid stability and achieving the UK’s decarbonisation goals.

Through accurate Half Hourly data, MHHS enables:

• Time-of-Use Tariffs: Consumers pay less when renewable power is readily available and more during peak demand when the grid relies on backup generation.
• Automated Demand Response: Smart systems can automatically shift energy-intensive activities like EV charging, heat pump operation, and water heating to periods of high renewable generation.
• Grid Services: Buildings with solar panels, batteries, or EVs can provide grid balancing services, earning money while supporting decarbonisation.

Plus, for Energy Managers, this new MHHS data transforms reactive monthly bill analysis into proactive optimisation strategies.

3. MHHS helps make Electric Vehicles a Decarbonisation Asset

Electric vehicles represent a massive new demand for electricity.

But they are also a potential solution to grid flexibility.

Smart technology enables EV drivers to contribute to grid flexibility.

• Smart Charging: EVs charge off-peak or when renewable generation availability is high
• Vehicle-to-Grid (V2G): EV batteries provide grid storage, releasing energy back to the grid during peak demand
• Load Balancing: Technology can help smooth out demand across EV charging points

4. Data-driven decisions Drive Clean Energy Investment

Ofgem estimates that its MHHS reform will save UK consumers up to £4.5bn in energy costs by 2045.

But the economic benefits go far beyond consumer savings.

By providing accurate price signals, MHHS creates the market conditions that drive investment in clean energy infrastructure.

• Investment Confidence: Accurate consumption data better forecasting for renewable energy projects
• Grid Optimisation: A smart grid can reduce the need for expensive grid infrastructure reinforcement work
• Data-driven Innovation: Granular data supports stronger energy strategies and investments

MHHS is the Hidden Foundation of Clean Power

For energy managers, MHHS represents the difference between managing energy costs and managing energy strategy. The new Half Hourly data it provides doesn’t just show what happened – it reveals what’s possible.

In a Net Zero world, that granular insight becomes your most valuable tool for delivering both carbon reductions and cost savings.

The true measure of MHHS success will be how Energy Managers make use of their new data to find waste, make better carbon-saving decisions and daily energy reductions.
