BASELINE – Power System Studies Experts in the UK
Integrating a solar or BESS system into the grid in Manchester? Enhancing electrical infrastructure for a data centre in London? With the right expertise, these projects can be executed with accuracy. Baseline brings that capability through advanced power system studies and power distribution services across the UK.
Our approach combines detailed steady-state and dynamic modelling with strict compliance to UK Grid Codes (G99/G100) and ENA standards such as G5/5, P28, and P29. Using advanced simulation tools, our experienced power system studies engineer team evaluates real operating conditions, protection schemes, and system behaviour. We also perform detailed validation for systems up to 400kV, supporting stable, efficient, and grid-compliant electrical networks across renewables, substations, and critical infrastructure. This further enhances low-voltage system performance through LT Electrical Services.
