SSE has installed 1 million smart meters, which means it has rolled out some 275,000 since the start of the year.
The firm reported it had installed 725,000 as of 31 December 2017.
SSE said it continues to increase the rate of installation, but to hit the 2020 deadline it must install a further six million smart meters in two years if all customers decide to have one.
This year, SSE’s rollout has averaged around 40,000 smart meters a month. To install six million by the end of 2020, it will have to rollout roughly 200,000 a month, which means immediately increasing its install rate by 400%.
SSE has previously called for government to relax the rollout date, but the department for business, energy and industrial strategy is yet to publicly admit that target will be missed by some margin.
Npower was fined last week for missing a much smaller target to install advanced meters at business premises. Beis said “suppliers must learn lessons from this to ensure similar mistakes are not repeated in the smart meter roll out”.
The department has also batted away recent criticism of the rollout from a group of MPs. This week it published a ‘myth busting’ document.
It states that smart meters will unlock bill savings, cannot be used to turn off household appliances without consent, are secure and won’t stop people switching.
However, one of the myths ‘exploded’ is that suppliers are not making enough progress on the rollout. Beis states they are collectively rolling out over 400,000 per month – and repeated that Ofgem can fine energy companies for missing targets.
If the intention is to install some 50m smart meters by 2020, that will require suppliers to immediately increase their collective install rate from 400,000 a month to around 1.4 million meters a month.
