The Distribution Network Options Assessment (DNOA) methodology is part of our DSO Strategic Network Planning approach to network investment which aims to provide the capacity needed to deliver the UK's decarbonisation targets by 2050 while retaining a clear focus on safety and reliability. The draft DNOA Methodology document can be found on our DSO Consultation Library here: DSO Consultation Library - SSEN
We are committed to annually review our DNOA process and to consult stakeholders on the proposed methodology. Our DNOA methodology aims to enhance industry transparency by outlining our decisions to meet future capacity needs across our licence areas. The methodology encompasses:
The DNOA methodology establishes an open and transparent decision-making process, signalling opportunity for Distributed Energy Resources (DER) and other flexibility providers to meet our forecast needs. This process ensures that decisions are made that optimise stakeholder value and emphasises energy efficiency. This iterative process is subject to annual renewal. We will be incorporating stakeholder feedback and lessons learned from conflict resolution. We remain vigilant in monitoring the industry’s maturity, drawing insights from other DSOs and NESO's Regional Energy Strategic Planning (RESP).
We will be holding a DNOA Methodology webinar on the 24th March, to sign-up, please register here: Event Details | Distribution Network Options Assessment Webinar.
A recording of the session will be made available at the same link after the event.
The link at the bottom of this section will take you to the online survey to capture your feedback.
The questions that we are asking are listed below.
1. Questions on our proposed DNOA methodology changes
a) Communication of Plans (slide 10) - Does this revised layout present the different DNOA outcomes in a clearer and more intuitive way?
b) DNOA Outcome Report (slide 11) - Do you think the added emphasis on flexibility data will be helpful for flexibility procurement?
c) ED3 transition (slides 15, 16) - Is the ED3 roadmap effective in explaining the transition timeline and overall process?
2. Questions on our overall DNOA process
a) Does the refreshed DNOA methodology, as part of our strategic planning process, provide you with the confidence that we are prioritising efficient and
economic long-term network solutions that provide capacity when required?
b) How do you use our DNOA outcomes reports in your planning process?
c) As an indicator of long-term flexibility needs, do the outcome reports clearly show where future need may be and where more detailed information can
be found?
d) What other changes would you like to see in this DNOA methodology or future updates?
3. Do you have any feedback on our consultation process with you?
4. Is there anything else you’d like to add?
