The Problem with Static Regulations Regulatory frameworks, such as the UK’s Electricity Transmission Design Principles (ETDP), are essential for ensuring that infrastructure is designed responsibly. They cover everything from technical needs (SP1) to environmental protection (SP2) and economic efficiency (SP3).

However, when these principles live in static PDF documents, they are prone to inconsistent interpretation. Demonstrating compliance requires laborious manual checks, and proving that a chosen route is truly the "best" option often involves battling subjective opinions rather than presenting objective data.

The Solution: "ETDP-as-Code" The future of compliant planning lies in making regulations machine-readable. By codifying principles directly into AI routing platforms, we turn static text into active algorithms. This concept, known as "ETDP-as-code," ensures that every generated option automatically adheres to the rules—or flags a clear justification when it doesn't.

How It Works: Principles in Practice Here is how abstract principles translate into automated logic:

• Lattice Towers First (Principle T3): The software can enforce a "rule-based default" for steel lattice towers. If a designer proposes an underground cable, the system’s "deviation switch" automatically triggers an A/B comparison, calculating the cost and impact difference to justify the exception.
• Designated Areas (Principle T4): Algorithms can encode industry standards like the "Holford Rules," inherently penalizing routes that cross National Parks or ridgelines. The system naturally favors alignments that utilize terrain for screening, minimizing visual impact without manual intervention.
• Climate Resilience (Principle T7 & S5): Resilience is no longer an afterthought. The platform integrates floodplains, erosion zones, and wind data, actively routing away from high-risk areas or enforcing safe tower elevations. This ensures designs are future-proofed against physical climate risks from day one.

Benefits for Regulators and Developers For regulators like Ofgem and DESNZ, this approach transforms the review process. Instead of wading through disparate documents, they receive Standardized Evidence Bundles. Every submission uses the same Red-Amber-Green rankings, cost metrics, and deviation logs, allowing for true "apples-to-apples" comparison across different Transmission Owners.

For developers, it provides a "presumption of compliance." By using a NESO-owned template pack, they can ensure their designs meet the minimum standards before they even leave the drafting desk.

The Roadmap to Adoption Transitioning to this model is faster than you might think. A typical adoption path—from authoring the templates to running full pilots—takes just 12 to 18 weeks. The result is a system where over 90% of submissions carry no bespoke methods, streamlining the path to consent.
