Green Engineering Strengthens Its Position as a Leading Partner for Utility Compliance Across the UK Grid

As the UK electricity network continues to expand to meet the demands of renewable generation, electrification, and large-scale storage, the importance of rigorous compliance has never been greater. Green Engineering is proud to reaffirm its role as a trusted specialist in ensuring design, construction, and commissioning compliance across DNO, IDNO and Transmission Operator networks nationwide.

From 33kV customer substations to 132kV and 400kV transmission enabling works, our team provides a comprehensive compliance-led approach that aligns every project with the exacting requirements of the relevant utility.

Ensuring Full Utility Adoption Readiness

Utility adoption is often one of the most complex and least understood elements of a project. Green Engineering supports clients by ensuring that designs and construction practices meet the specific standards set by the adopting network, including:

• G99 and Grid Code compliance (formerly G59)

• ENA Engineering Recommendations (ER P28, P29, ER G5/5, ER S34 and others)

• DNO-specific civil, electrical, protection and control standards

• SPT Appendix F enabling works compliance for transmission sites

• EHV cable route installation standards and jointing requirements

Our proactive approach ensures that utility comments, deviations, and clarifications are addressed early — reducing delays, redesign cycles, and the risk of non-adoption at construction stage.

Compliance Throughout the Project Lifecycle

Green Engineering embeds compliance at every stage of the engineering process:

• Survey coordination and constraints assessments

• Primary and secondary design with full standards alignment

• Earthing, protection and control design validation

• Civil, structural and drainage designs aligned to utility requirements

• Construction readiness and on-site technical oversight

• End-to-end document control and as-built verification

This creates transparency across all disciplines — enabling our clients to move confidently from early feasibility through to energisation.

Supporting a Low-Carbon Future Through Responsible Engineering

Achieving a reliable, future-proof grid is not just about building infrastructure; it requires engineering discipline, regulatory understanding, and absolute compliance. Green Engineering brings all three together to ensure that projects are not only technically sound, but fully aligned with the standards required for long-term adoption and safe operation.

As sustainable engineering companies become pivotal to the UK’s energy transition, Green Engineering continues to lead with integrity, precision, and a steadfast commitment to utility compliance across every voltage level — 33kV, 66kV, 132kV, 275kV, and 400kV.
