understanding P272 and the opportunity for Solar PV installers – Featured in the latest Inside Clean Energy Magazine

Egnida’s latest blog on the looming changes to Ofgem’s P272 settlement code and what the opportunity is for solar installers has been featured in the latest edition of Inside Clean Energy. You can download a copy by Clicking Here – Inside Clean Energy Magazine.

Egnida provides complete energy solutions for customers so we understand all aspects of energy management from energy procurement and metering through to demand side management, battery storage and Solar PV installations. We know that most competent commercial Solar PV installers understand the technical installation and FITs and many that analyse the financial benefits of a solar installation for their customers will have some understanding of half-hourly usage data. However, many installers still struggle with customer tariffs and usage data, particularly non half-hourly data. Clearly, with the reduction in FITs and increases in electricity market prices, accurately analysing how much Solar PV output is likely to be absorbed on site is a much more critical aspect to the associated business case. Most large sites will be “half-hourly” and therefore the customer can supply their half-hourly electricity load data. Half-hourly metered sites can be identified from the customer’s MPAN (Meter Point Administration Number) which is shown on their electricity bill. Profile Type “00” indicates half-hourly metering as in the example below:


Larger non half-hourly “maximum demand” metered customers ie those of Profile Types (Classes) 05 (<20% Peak Load Factor), 06 (between 20% and 30% Peak Load Factor), 07 (between 30% and 40% Peak Load Factor) and 08 (>40% Peak Load Factor) are currently effectively billed based on standard load shapes allocated to their Profile Classes. This makes it much more difficult for those outside the energy industry to interpret and accurately analyse how much Solar PV output is likely to be absorbed on these sites based on billing usage data alone. However, P272 is going to change this in the near future.

P272 is a change in electricity industry legislation requiring circa 160,000 UK business sites with Profile Classes 05, 06, 07 and 08 and Automatic Meter Reading (AMR) meters to move to half-hourly electricity settlement. As such, customers that have these meters installed that are capable of recording half-hourly consumption data are also required to appoint an industry approved half-hourly Data Collector and Meter Operator so that from 1st April 2017 they can be billed under the new arrangements. As an experienced energy management company Egnida manages this process on behalf of customers together with the associated changes in electricity supply contract arrangements. Depending on the difference in customer’s actual load profiles compared to the standard shapes used previously their bills can potentially increase or decrease. Either way, billing and charging structures for these types of meters will inherently become more complex.

The good news for Solar PV installers is that for those customers that will see an increase in day time electricity costs the case for solar will improve. In addition, the availability of half-hourly data will make it easier to more accurately predict how much of the Solar PV output will be absorbed on site further removing risk from the business case. As an added bonus, for suitable sites, hybrid solutions comprising Solar PV, battery storage, Demand Side Response and tailored electricity supply contract arrangements can offer further efficiencies and cost savings for customers particularly for those with larger portfolios of relatively low usage sites.
