Shred the Peak: How RMLD Customers Can Help Reduce Energy Costs and Support Sustainability
The Reading Municipal Light Department (RMLD) offers Shred the Peak, a suite of programs designed to help customers actively reduce electricity usage during peak times. By participating, customers can help lower power supply costs, keep electricity rates affordable, and contribute to RMLD’s non-carbon goals.
Understanding energy peaks and their impact
Energy peaks occur when electricity consumption reaches its highest levels within a specific timeframe. These peaks significantly impact power supply costs and environmental sustainability:
Cost Impact: Peak electricity is expensive, driving up wholesale capacity and transmission costs, which are ultimately passed on to customers.
Environmental Impact: Meeting high demand often requires using inefficient, carbon-intensive power generators.
When do peaks occur?
RMLD experiences two types of peaks that affect power supply costs:
Annual Peak: Occurs once per year, typically on a hot and humid weekday between June and August from 2–7 PM.
Monthly Peaks: Occur once per month, usually on the hottest or coldest weekday of the month. Summer peaks happen between 2–7 PM, while winter peaks occur from 5–9 PM.
The financial benefits of reducing peak usage
By lowering energy use during peak times, RMLD can achieve significant savings:
Reducing electricity use by 1 megawatt (1,000 kW) during the annual peak can save approximately $100,000 in future power supply costs.
Reducing usage by 1 megawatt during a monthly peak can save around $12,000 per month.
How customers can help ‘Shred the Peak’
During predicted peak windows, customers can take simple actions to conserve electricity:
Turn off unnecessary lights and electronics.
Delay using major appliances like washers, dryers, and dishwashers.
Postpone electric vehicle charging.
Adjust thermostat settings (78°F+ in summer, under 70°F in winter).
Cook outdoors or use energy-efficient cooking methods.
Turn off pool pumps.
Close blinds/curtains in summer; limit space heater use in winter.
Ways to participate in Shred the Peak
1. Sign Up for Peak Alerts
Receive email notifications when a peak is predicted so you can take action. Alerts are also posted on RMLD’s website and social media. Sign up for peak alerts here.
2. Enroll in Connected Homes
The Connected Homes program enables residential customers to enroll eligible smart devices that automatically adjust their usage during peak times. Customers receive quarterly bill credits for participating. Learn more here.
3. Switch to Time-of-Use Rates
Customers can opt into Time-of-Use Rates, where electricity costs vary based on demand. Peak hours have a higher rate, while off-peak hours offer savings. A one-year commitment and a special meter are required. Contact RMLD Customer Service at 781-942-6598 for details.
4. Explore Load Management & Solar Incentives
RMLD provides rebates for installing Load Management Devices and solar incentives for residential and commercial customers. Learn more here.
RMLD’s commitment to peak reduction
RMLD has implemented several in-territory energy solutions to reduce peak demand:
Solar Choice Program: Community solar arrays producing 2.7 megawatts.
2.5-Megawatt Distributed Generator: A natural gas-powered unit running during peaks.
5-Megawatt Battery Storage System: Used to offset peak demand.
By participating in Shred the Peak, customers can help maintain lower electricity rates and contribute to a more sustainable energy future. Get involved today and make a difference!
