Connection strategy & feasibility
Compare credible DNO and transmission routes, identify constraint and reinforcement exposure, and focus time and land spend on positions worth advancing.
Independent grid & power systems consultancy · Great Britain
Practical grid advice for generation, storage and large demand.
Support for developers, investors and delivery teams, from early connection strategy through offer review, network engagement and delivery.
Taking on selected new engagements
Services
Grid advice for specific project decisions.
This may be a focused review, or ongoing ownership of the grid workstream where continuity is useful.
Applications & Gate 2 strategy
Shape competent applications, modification strategy and evidence, then deal with the practical programme implications of the reformed queue.
Offer & contract diligence
Turn connection offers and works agreements into a clear view of dates, costs, dependencies, liabilities, access rights and decision points.
Network engagement & challenge
Lead technical discussions with DNOs, TOs and NESO, close information gaps and challenge positions that are not supported by the engineering or the rules.
Curtailment & access risk
Assess non-firm access, ANM and constraint exposure so the connection assumptions used in the investment case are explicit and defensible.
Client-side grid lead
Own the grid workstream through development and delivery, coordinating studies, designers, network companies and senior project decisions.
Connections reform
Gate 2 offers are landing. Demand rules are still changing.
Projects now need to understand what their offer means, what should be accepted or challenged, and which dependencies could delay delivery.
Sectors
01
Generation & storage
Solar, wind, standalone BESS and co-located or hybrid projects, from distribution connections to transmission-scale infrastructure.
Explore sector 02Large demand & infrastructure
Due diligence and connection strategy for identified sites and live opportunities, including data centres and major industrial demand.
Explore sector 03Commercial & distributed energy
Senior DNO-facing support for installers and developers where a G99, G100 or multi-technology site has become commercially awkward.

Examples of the work.
Project names and details are anonymised to protect clients. Each example explains the issue reviewed and the decision it supported.
Transmission solar & BESS
01Connection and programme strategy for projects at several-hundred-megawatt scale, including enabling works and transmission interface risk.
Connection offer challenge
02Technical and commercial review of distribution and transmission offers, including reinforcement, charging, milestones and queue position.
Curtailment diligence
03Independent review of ANM and non-firm access assumptions to understand the real operational and investment exposure.
Large demand due diligence
04Route and phasing advice for identified sites in the 50–200 MW range, separating credible connection evidence from optimistic capacity claims.
Hybrid connection strategy
05Advice on shared infrastructure, import/export structure and the connection implications of combining generation, storage and demand.
Portfolio prioritisation
06Screening and comparison of network positions to direct development spend toward the strongest opportunities.
Network interface
Comfortable on both sides of the table.
Experience working inside a GB DNO and directly with all GB DNO groups, NESO and the transmission owners. This helps when the published process does not answer the project's practical question.

About
Independent and founder-led.
Walledge Davis Consulting is led by Kieran Davis MEng MIET, an electrical engineer specialising in grid connections and power systems.
Experience spans utility-scale renewable development, transmission-connected infrastructure and network planning within a GB distribution network operator.
The working style is direct: explain the engineering in commercial terms, identify what is evidence and what is assumption, then recommend a practical next action.
