Performance summary 2019/2020

  • Overview of outputs

    Improve by 20% the time taken to provide a response to customers who want to use LCTs.(See note 1 below)

    We are receiving increased volumes of notifications which we are addressing quickly, but the volumes of enquiries mean that we have not been able to improve our response times. 

    Identify LCT hotspots using information from smart meters, expert organisations and local authorities, and use this information when making decisions.

    The project LCT Detection has proven that a model can be developed to spot unregistered LCTs connected at household level. The data gathered from this project has been used to refresh the LCT hotspot data held in our asset register database and mapping system.

    Selectively replace assets using larger assets in areas where more LCTs may be connected to our network.

    We carried out 27 asset replacement projects, using larger assets, as a result of using information about LCT hotspots.

    Reduce costs for future customers by developing smart solutions to provide alternative and innovative techniques for managing our network.

    We had a range of innovation projects in progress during the year.

    Provide additional network capacity by using traditional or smart methods.

    We have continued to develop the Flexible Power brand and increased the number of substations utilising flexibility from 71 in 2018/19 to 122 in 2019/20. 

  • Overview of outputs

    Install oversized transformers when replacing assets in areas where demand for power may become higher than equipment can cope with.

    We installed 27 oversized transformers.

    Use larger cables when installing new network in LCT hotspots.

    We installed 2.93km of larger cable in LCT hotspots.

  • Overview of outputs

    Replace 55km of overhead lines in National Parks and AONBs with underground cables.(See note 1 below)

    To date during RIIO-ED1, we have replaced 29.12km of overhead lines with underground cables for visual amenity in AONBs.

  • Overview of outputs

    Make sure all replacement vehicles have lower CO2 emissions than those they are replacing.

    WPD operational vehicle emissions have reduced by 11% compared to 2018/19, but there have been increases in vehicle emissions reported to us by our contractors. This means we have slightly missed our target for 2019/20.

    Make 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)

    We have not completed any depot construction or refurbishment works during 2019/20.

    Reduce 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 in the amount of waste sent to landfill, and we have achieved our target for the whole of RIIO-ED1.

    Reduce our carbon footprint by 5%.(See note 1 below)

    Our business carbon footprint has reduced by 20% compared with 2012/13. We have beaten our in-year target.

  • Overview of outputs

    Reduce by 75% the amount of oil lost through leaks from oil-filled cables.(See note 1 below)

    The leak volume from oil- lled cables has signi cantly decreased. We have beatenour in-year target.

    Reduce 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 0.19% in 2019/20 for the whole of our area. However, we missed our in-year target in the South West.

    Install effective oil containment 'bunds' around plant containing high volumes of oil.*(See note 1 below)

    We have completed work on 173 new and refurbished bunds so far in RIIO-ED1, going further than our forecast of 104 bunds.

Note 1: This target is for the full eight-year RIIO-ED1 period, not for each separate year.

Note 2: This target is for each year of RIIO-ED1.
