In a weekly report produced by Ofgem with regards to the FIT Deployment Caps, the >50Kw band has risen to 80% capacity. The result shows a 25% increase from the previous weeks 55%, showing a drastic 25% increase as the FIT Tariff draws to a close on April 1st.

The news will come as no surprise to those installing these systems as there has been a growing rise towards the cap over the previous few months, as installers look to fit as many systems as possible prior to the FIT tariff closing. However, the information does show that the >50Kw band is under pressure.


Fig 1: The ’TP1 2019 Deployment ‘chart shows which caps have been filled in this quarter (red) and those that are still open (blue).


Along with other bodies representing the Solar Industry, such as the Solar Trade Association, we have requested more frequent updates from Ofgem to limit the risk of the capacity bands being filled to planned installations.

A spokesperson for Ofgem commented:

“It is worth noting that although these figures were published Friday (15th March), they represent the caps as of midnight on Tuesday (12th March), so there have been 3 more working days for people to apply and therefore contribute to the cap.
We are not planning on publishing more frequent updates. It is for generators and installers to negotiate the risk associated with closure, and Ofgem cannot offer advice beyond clearly stating the rules in our guidance.”


Adrian Simpson, Director of Policy, at HIES commented:

‘’Although this does not affect domestic installations (under 10Kw), which continue to perform at well beneath the caps, we are concerned that there is a very real possibility that businesses that have had Solar PV systems installed in this sector of the market will learn that they will not receive the tariffs promised long after those installations have taken place. The publicity that may follow this could further damage the market at a crucial time in its evolution. It’s challenging, because the Ofgem information will always be out of date, but we would urge installers in this sector to take a proactive approach in managing client expectations.”



Important Update

Ofgem this morning published an update to the deployment caps showing the >50KW cap has now been reached.

The information shows that the final installation to quality for the cap occurred on the 13/03, meaning that anything registered after this date will not receive the FiT. Ofgem have previously stated that it is the responsibility of the generator and the installer to manage this process and they will not be in a position to assist in any way.’
