Performance summary 2022/2023
Overview of outputs
19Improve by 20% the time taken to provide a response to customers who want to use LCTs.(See note 1 below)We are continuing to see a rapid increase in the number of LCT enquiries we receive but new systems put in place during 2022/23 have enabled us to reduce our response time to 0.69 days, a 76% reduction from our benchmark performance.
20Identify LCT hotspots using information from smart meters, expert organisations and local authorities, and use this information when making decisions.The development of the “Network Investment Forecast Tool” has enabled us to add predicted LCTs to our LV network and highlight areas that will reach capacity.
21Selectively replace assets using larger assets in areas where more LCTs may be connected to our network.We carried out 87 projects using larger assets, as a result of using information about LCT hotspots. This is a 207% increase from last year’s activities.
22Reduce costs for future customers by developing smart solutions to provide alternative and innovative techniques for managing our network.We had a wide range of innovation projects in progress during the year.
23Provide additional network capacity by using traditional or smart methods.We have continued to develop the Flexible Power brand and now have 294 substations using flexibility
Overview of outputs
24Install oversized transformers when replacing assets in areas where demand for power may become higher than equipment can cope with.We installed 56 oversized transformers, a 266% increase on last year’s performance
25Use larger cables when installing new network in LCT hotspots.We installed 6.6km of larger cable in LCT hotspots.
Overview of outputs
33Replace 55km of overhead lines in National Parks and AONBs with underground cables.(See note 1 below)In RIIO-ED1, we have replaced 39.5km of overhead lines with underground cables for visual amenity in AONBs.
Overview of outputs
26Make sure all replacement vehicles have lower CO2 emissions than those they are replacing.NGED operational vehicle emissions have reduced by 11% compared to 2012/13. This has included reduced emissions from both NGED and contractor vehicles.
27Make sure all new or substantially refurbished buildings meet, as a minimum, the excellent standard under the Building Research Establishment Environmental Assessment Method (BREEAM).(See note 2 below)During 2022/23 NGED applied for BREEAM certification for a new building in Ludlow, we are waiting for the decision and we are still awaiting the results of an application from 2020/21 for refurbishment works at one site.
28Reduce the amount of waste sent to landfill by 20% over the first two years of RIIO-ED1 and 5% per year after this.We have seen a reduction of 37% in the amount of waste sent to landfill, and we have achieved our target for the whole of RIIO-ED1.
29Reduce our carbon footprint by 5%.(See note 1 below)Our business carbon footprint has reduced by 36% compared with 2012/13.
Overview of outputs
30Reduce by 75% the amount of oil lost through leaks from oil-filled cables.(See note 1 below)The volume of oil leaked from fluid filled cables fallen by 45%, while we have missed our ambitious target in this area we continue our efforts to repair leaks quickly and replace these assets to reduce the amount of oil leakage.
31Reduce by 17% the amount of SF6 gas that is lost from switchgear.(See note 1 below)The amount of SF6 gas lost as a percentage of the total amount of SF6 used on our network has reduced from 0.47% in 2015/16 to 0.14% in 2022/23 for the whole of our area.
32Install effective oil containment 'bunds' around plant containing high volumes of oil.*(See note 1 below)We have completed work on 237 new and refurbished bunds so far in RIIO-ED1, going further than our forecast of 104 bunds.
Note 1: Targets are for the full eight year RIIO-ED1 period, not for a discrete year
Note 2: Target to be achieved each year of RIIO-ED1.
