Peak Shaving & Energy Cost Optimization
Cut peak demand charges, optimize energy cost
Problem
Industrial electricity bills include significant demand charges based on peak power consumption. Even short peaks can result in high monthly charges. Time-of-use tariffs make certain hours extremely expensive.
Site Conditions
- High demand charges in electricity bill
- Time-of-use tariff structure with significant peak-off-peak spread
- Predictable load profile with identifiable peak periods
- Grid connection with capacity constraints
PSN Solution
PSN Energy BESS discharges during peak tariff periods to reduce grid import and flatten demand profile. The EMS predicts and manages peak periods to minimize both energy charges and demand charges.
Operating Logic
Off-Peak Hours
BESS charges from grid at low tariff rates
Peak Hours
BESS discharges to cover factory load, reducing grid import
Demand Peak Detected
BESS rapidly discharges to clip power peaks and reduce demand charges
Grid Failure
BESS provides uninterrupted backup power
Key Benefits
Reduced peak demand charges (15-30% bill savings)
Lower energy cost through time-of-use arbitrage
Deferred grid upgrade costs
Improved power quality and reliability
