The energy industry is going to start asking for more from businesses like yours.

If you’ve dealt with half-hourly electricity meters, you’ve probably come across terms like MOP, DC and DA. You might even have contracts in place for them.
Knowing what each of these roles does, and how they work together, is not always clear. But it's about to become very important that you know your stuff.
A major industry change, Market-wide Half-Hourly Settlement (MHHS), is on the way, and it’s going to make these services relevant to even more businesses, regardless of size.
Before that happens, now’s a good time to get to grips with what they are, how they impact your bills, and where to turn if something’s not working.
MOP stands for Meter Operator.
A MOP is the company that installs and/or looks after your electricity meter.
Every half-hourly meter needs a MOP agreement. It’s a bit like having a mobile phone: you don’t just need a SIM card (your supplier), you also need a phone that works (your meter). And someone needs to keep that phone in good shape.
The MOP is responsible for:
You can choose your own MOP, but most businesses don’t. They just let the supplier appoint one and often pay more than they need to without realising.
DC stands for Data Collector.
Once your meter is up and running, it needs to send your usage data somewhere. That’s the DC’s job.
They virtually pull the data from your meter, usually every half hour for larger businesses. The data shows how much energy you’re using and when.
The DC:
Again, you can choose your own DC, but many businesses don’t know that either.
DA stands for Data Aggregator.
The DA is the last stop in the data chain.
They take everything the DC has collected and double-check it.
The DA asks:
Is it complete?
Does it make sense?
Has anything gone missing?
Once that’s done, they hand it over to your supplier and the industry systems for billing and settlement.
You don’t interact with the DA much but if they don’t do their job properly, your bills could end up wrong, delayed, or based on estimates.
In the past, most businesses didn’t really need to know about this stuff. Your supplier handled it. You got your bills. End of story.
But things are changing.
That's where the major industry reform comes in: Market-wide Half-Hourly Settlement (MHHS).
It's going to bring half-hourly data and everything that comes with it, to all businesses and eventually households too.
That means:
And if you don’t know how your setup works, or who’s responsible for what, it’s much harder to spot if something’s wrong.
If you don’t already know who your MOP, DC and DA are, it’s worth finding out. You could be paying too much or stuck with a setup that doesn’t suit your business.
