Review Meter Operator (MOP) Data Collector & Data Aggregator (DC/DA) costs and service

We can help you to set up contracts on your behalf, and you’ll know that you’re getting a great deal without having to do any of the running around.

  • It is a legal requirement for all half hourly electricity supplied meters to have a valid MOP agreement in place. The contract encompasses the supply, maintenance and communications for sending your data to your energy supplier.
  • We often find savings and many businesses are on costly out of contract rates because MOP contracts are separate to supply contracts and often overlooked. In some cases we have seen costs for a MOP reduced by 50%!
  • Data Collector & Data Aggregator (DC/DA) agreements are a requirement for all half hourly electricity supplies. There are number of specialists that provide these services and many businesses are not given options, with energy suppliers applying one by default, if not instructed otherwise. Jonstar works in partnership with the leading providers, enabling us to advise on and source the right option for your business.


  • We will look to analyse all MOP / DC / DA agreements for your business, not only can this produce year on year savings, but we can work with you to get visibility of your data with reports to enable insights to support further optimisation and efficiency.

Capacity Review

We can help you to review your consumption, and support you in making changes

  • All half hourly electricity supplies have an allocated capacity (KVA) and separate charges are applied per KVA. Many businesses are paying excess costs for unnecessary capacity, whilst others may incur penalties for exceeding their agreed KVA.
  • Ofgem has undertaken regulatory changes through the P272 initiative, seeking to bring large non half hourly supplies into half hourly metering. Many businesses have been set a default capacity which is typically not optimised and we can help to analyse and either give peace of mind or demonstrate savings.
  • Ofgem also introduced new measures to penalise businesses that exceed their agreed capacity with increased charges from 1st April 2018. Known as Distribution Change Proposal (DCP) 161, the increased charges are designed as a disincentive to prevent businesses from trying to avoid paying for a higher agreed capacity. There are however still ways to look at shifting energy usage during peak demand to reduce charges.


  • By analysing the peaks in your electricity consumption (Maximum Demand), taking account of your operational plans in relation to your agreed capacity, significant savings may be made.

On Site Generation – Behind the Meter (BtM)  

Behind the Meter (BtM) – Explore our range of ways to access Sustainable Technologies

When you consider that electricity prices have been increasing massively, with this trend expected to continue, it is important to consider the main drivers for continued increases are taxes to fund UK renewable energy and infrastructure initiatives. 

Businesses such as yours are increasingly looking at ways to take ownership of their energy and avoid rising costs and taxes by investing in or taking advantage of specific funding that has been set aside for renewable solutions.

Technology is rapidly evolving and giant leaps have been made in battery storage, solar and other forms of renewable generation with powerful software and machine learning capabilities providing new opportunities for business.

Demand Side Response (DSR) is a growing phenomenon, with high energy users able to reduce their demand during peak times, or when the National Grid asks them to. This may, where suitable, involve shifting high energy activity to periods of lower demand and where battery storage has been implemented, by storing energy and distributing this back into the grid at times of peak demand. Opportunities to reduce charges and/or create revenue streams are increasingly being capitalised upon by forward thinking businesses.

Our network of leading UK engineers can support clients nationally with a range of undertakings, we have successfully supported clients with projects that have secured their energy supply, protected against future price rises and massively improved their green credentials.

Solar PV is now a mature market, however new technology is increasingly agile and efficient; furthermore the ways to access this for your business are wider than ever. If you have explored solar and found it wasn’t viable now is the time for a fresh look. If you are yet to look at the figures, get in touch and we can arrange a free and comprehensive desktop audit.

Accessing Sustainable Technologies:

  • Private investment – where you are able to invest using your own funds for the most rapid ROI
  • Asset Finance – With the project funded by asset or commercial finance
  • Power Purchase Agreement (PPA) – Access specific funding for sustainable technology with zero upfront costs
