TRANSCRIPT
• The need:
– Flexibility in de-regulated markets
globally
– Cost-effective replacement for MDI
metering, upgrade later when required
– Multi-utility application
– Low cost communications capability
• The Need
A cost-effective solution
from a reliable platform,
to meet the demands of
a changing commercial
and industrial market environment
• The need:
– A solution for sub-100kW sites in UK
– Low cost communications capability
– Flexible communication systems
– Reliable, cost-effective 30min data
for settlements and Energy Management
• The Solution
