Emerald Tide Delivers SNRG Smart Grid at Harwell Campus

A Smart Grid integrates grid power, renewable generation, battery energy storage and back-up generators, to create a resilient (2N), private distribution network, managed through smart controls to interpret usage patterns, weather and respond to faults. This results in increased resilience, carbon reduction, tarriff reduction and maximisation of contracted loads from the grid. 

Problem:

Harwell has a significantly high contracted loaded, but low materialised load when measured at 11kV. The distribution network was DNO owned to LV metering at the individual buildings. 

Solution: 

Metering at 11kV (HV), enabled behind-the-meter integration of grid power, renewable solar generation, battery energy storage and backup generators. Managed through smart controllers, diverse energy usage profiles, weather patterns and fault detections, could all be monitored. 

Outcome:

This enables the existing grid contracted load to be reserved for Harwell's future masterplan development, with out costly and protracted grid reinforcements. 

Lower energy tarriffs, as power is partly generated from low cost solar, reduced standing charges, and power brought in low triad periods and discharged via batteries at high tariff periods.
