High electricity costs & demand charges
Half-hourly metering, TOU tariffs and capacity charges mean energy cost structure is multi-layered. Systems are modelled against actual billing data.
ContactEngineered solutions to reduce energy costs, manage peak demand and improve operational resilience. Designed around real-world site constraints — not ideal conditions.

Half-hourly metering, TOU tariffs and capacity charges mean energy cost structure is multi-layered. Systems are modelled against actual billing data.
DNO capacity constraints, G99/G100 thresholds and agreed supply capacity restrict what can be installed without grid reinforcement.

Roof-mounted and ground-mount commercial PV arrays from 50 kWp to multi-MW. Yield modelled against half-hourly site consumption data and DNO export limits.
Yield modelling against half-hourly consumption data. System sizing, single-line diagrams, financial model with sensitivity analysis.
G59/G99/G100 application management. DNO liaison, protection relay settings and export limitation configuration.
Managed installation programme with structural coordination, electrical containment, inverter and BESS commissioning preparation.
Witness testing, protection relay verification, EMS configuration, DNO sign-off and full commissioning documentation pack.
Live monitoring, generation vs modelled yield review, battery scheduling refinement and demand response programme enrolment.
We model your system against actual half-hourly consumption data before recommending anything. No generic sizing. No overselling. A clear picture of what works for your site.
