Supporting SSEN Distribution to Become the First UK Electricity DNO to Set 1.5°C Aligned Science-based Targets

Objectives

Scottish and Southern Electricity Networks (SSEN) is a District Network Operator (DNO) that distributes power to 3.7 million homes across the UK. SSEN is responsible for maintaining the power networks to ensure the homes it serves receive an uninterrupted supply of energy.

The company commissioned Anthesis to carry out a review of its carbon emissions portfolio, develop a science-based target (SBT) and determine an agreed route to achieving the target by 2033. SSEN also required support in submitting its targets to the Science Based Target Initiative (SBTi), and upon validation, embedding the ambition into its wider business plan.

Project

Anthesis collected the necessary data required to calculate SSEN’s footprint, covering scope 1 to 3, and used this data to calculate the SBT trajectories. We then hosted a workshop with experts within SSEN to gather and understand the planned carbon reduction initiatives.

Using this information as well as regular meetings with the client, we modelled the reduction measures and developed onto tableau software, enabling the client to dynamically visualise how different measures could help the company progress towards the SBTs. Anthesis then supported SSEN with its submission to the SBTi.

Following validation, Anthesis has worked with SSEN to feed the SBTs into the wider regulated business plan and its annexes, such as the Environmental Action Plan, and to embed the action plan within the business to ensure that all areas are working in support of the plan.

The project was split into 2 main phases

1. Calculating and summarising SSEN’s Scope 1, 2 and 3 emissions and modelling its SBT carbon reduction pathway to 2050.
2. Scenario analysis and identification of reduction measures to help SSEN reach its targets. The reduction measures were modelled against SSEN’s calculated trajectory.

Services

• Conducted value chain screening and baseline emissions inventory.
• Modelled emissions pathways and proposed reduction strategies.
• Prepared summaries, data visualisation models, and communications to support internal engagement.
• Carried out a workshop to understand the activities already being carried out by SSEN Distribution.
• Supported the SBTi submission and target validation process.
• Continuing to provide support in the development and implementation of SSEN Distribution’s SBTs.

Impacts

Anthesis supported SSEN Distribution to become the first Electricity DNO to set science-based targets in line with a 1.5°C pathway. SSEN Distribution’s SBTs are:

• To reduce absolute Scope 1 and 2 GHG emissions 55% by 2033 from 2020 base year
• To commit that 35% of suppliers by spend covering purchased goods and services and capital goods will set SBTs by 2026

Further to this, SSEN Distribution has begun embedding the ambition within its regulated business plan, to ensure that targets are met.
