How to lower your business electric bill in Massachusetts
Start with what you use, when you use it and how your bill is calculated. Efficiency, eligible rate options, supplier terms and battery storage work on different parts of an Eversource or National Grid bill.
What runs a commercial electric bill up the most?
Often the demand charge, especially for facilities with sharp peaks. On most commercial and industrial rates, the single highest 15 minutes of power use in the month is billed per kilowatt, so one short peak can set a large share of the whole bill.
Start with a full year of bills and interval data
Separate supply and delivery, then find the energy charges in kWh and demand charges in kW. Capacity may be included in supply or passed through separately. These costs overlap on the bill; do not add them twice.
Compare your current operation under each eligible rate and supply offer first. Then model efficiency, load shifting, solar or a battery against that baseline, including fees and the program revenue your facility would actually keep.

Eight ways to lower a Massachusetts business electric bill
Ranked roughly from least effort to most, not by size of saving. Most facilities use several.
01
Efficiency, LED and Mass Save
Lowers:EnergyDemand
What it can do
LED lighting, variable-speed drives, compressed-air leak repair and controls cut kWh every hour they run, and take a little off the peak. Eligible projects can receive Mass Save incentives. Start with an assessment and check eligibility and approval requirements before ordering equipment.
What to watch
Most of the saving lands on the energy part of the bill. A plant whose peak comes from a few large machines starting together will still see that peak.
02
Check your rate and your power factor
Lowers:DemandEnergyFixed
What it can do
Compare eligible delivery options as well as your power factor. National Grid G-3 offers optional coincident-peak transmission billing; Eversource G-3 has similar elections in some service areas. National Grid G-3 also uses the greater of peak kW and 90% of peak kVA, so power factor can affect billed demand.
What to watch
Eligibility and rules vary by utility and service area. Compare 12 months of bills and interval data before switching; National Grid and the Greater Boston and Cambridge Eversource G-3 coincident-peak elections require at least 12 consecutive months. Ask a qualified electrical professional about power-factor correction.
03
Shop your supply
Lowers:Energy
What it can do
Large customers on variable basic service see supply prices change monthly, with winter often more expensive. Compare eligible fixed basic service options and competitive supply offers over a full year, including how each treats capacity costs.
What to watch
A fixed headline price may still include pass-through charges or other conditions. Read capacity treatment, usage bands, renewal terms and termination fees. Changing supplier does not change the utility’s delivery tariff.
04
Stagger start-ups so spikes don’t stack
Lowers:Demand
What it can do
Starting compressors, chillers, ovens or chargers one after another can reduce overlapping warm-ups and lower demand during the intervals your tariff bills.
What to watch
Production has to allow the change. Another high interval can still set the billed peak, and minimum billing demand or power-factor rules can limit the benefit.
05
Lower your load in New England’s peak hours
Lowers:Energy
What it can do
Capacity costs can follow your load during New England’s annual peak. On a capacity pass-through contract, lowering the load that sets your capacity tag can reduce later supply charges. Monthly transmission peaks are a separate calculation under eligible delivery options.
What to watch
Grid peaks are known after the fact. Supplier terms determine when a lower capacity tag reaches your bill; an all-in fixed contract may treat it differently. Do not confuse the annual capacity peak with your own monthly maximum or the monthly transmission peak.
06
Get paid by ConnectedSolutions and Clean Peak
Lowers:Paid separately
What it can do
ConnectedSolutions offers performance-based summer payments: up to $200 per kW per summer for National Grid daily dispatch, with targeted dispatch available under separate event and payment rules. Qualifying storage can also generate Clean Peak certificates for eligible performance in the program’s seasonal windows.
What to watch
Payments are separate from utility-bill savings. Performance rules, enrollment, incentive caps and provider fees affect what you keep. Check certificate ownership and co-participation terms before adding program revenues together.
07
Solar
Lowers:Energy
What it can do
On-site solar reduces the electricity you buy while it is generating. Eligible projects may also qualify for Massachusetts solar incentives and export credits; the value depends on the project and tariff.
What to watch
Demand savings depend on solar output during the interval that sets your billed peak. A cloudy interval or an evening peak can limit the benefit. Compare available space, interconnection requirements and the value of adding storage.
08
Battery storage
Lowers:DemandEnergy
What it can do
A battery discharges through the 15-minute peaks that set the demand charge, so the meter sees less than the plant draws, and nothing about how you operate has to change. Eligible systems may also earn ConnectedSolutions payments and Clean Peak certificate revenue, subject to participation and ownership rules. A first-pass screen usually puts the saving at about 1–4 months of the electric bill a year, but it varies a lot by site and is hard to know without a full analysis. Your free assessment shows the real number for your facility. With purchase, 2–3 year payback for most customers, before tax benefits.
What to watch
Demand savings depend on reducing the intervals your tariff bills, and a battery can run out on a long peak. QoreAI re-plans every 15 minutes from what it sees at the site, so it adapts to new equipment, shifts and unexpected load. Payback includes on-bill savings and utility program revenue; excludes federal tax credits and depreciation. Actual results vary by facility.

Tips and tricks to lower your demand charge
The demand charge is the part of your bill set by your highest spike. These habits keep spikes down for free. The first matters most; try it below.
01
Don’t start big equipment at the same time
Bring compressors, furnaces, ovens, chillers and EV chargers on one after another, a few minutes apart, so their start-ups don’t stack into one 15 minutes.
02
Watch the Monday-morning restart
After a weekend or a shutdown, HVAC, process heat and air all pull hard together. That 7 am Monday spike often sets the month.
03
Move flexible loads out of your rate’s peak hours
Batch runs, pre-cooling, charging and tests that can run earlier or later cost less there, and on many rates only spikes inside the demand hours count.
04
Read the demand line every month
The kW figure on your bill tells you whether a spike set the charge. Catching it the month it happens is how a habit sticks.
- Lights and base load
- Oven or furnace heat-up
- Chiller pull-down
- HVAC after the weekend
- Air compressor start-up
- Highest 15 minutes
- 435 kW
- What the meter bills
- Demand charge vs all at once
- 0%
- It scales with the billed peak
The highest 15 minutes average 435 kW, starting at 7:00 am. Every start-up lands in the same interval.
Started together, the warm-ups stack to 435 kW. Started in turn from 5:00 am, the same machines peak at 280 kW, a 36% smaller demand charge.
Illustrative loads. A motor’s start-up surge lasts seconds and barely moves a 15-minute average; what sets the charge is several machines working hard through the same quarter-hour, like a warm-up after a weekend.
Staggering loads can lower demand when it reduces the intervals your tariff bills. Production schedules may limit what you can move, and another busy interval can still set a higher peak. A battery can supply part of that short burst of power, reducing the draw at your meter while equipment keeps running. The result depends on your load, tariff and system size.
Why it is harder than a list
We compare the options against a year of bills and interval data, then weigh bill savings, program benefits and system costs together. QoreAI re-plans every 15 minutes from what it sees at the site, so it adapts to new equipment, shifts and unexpected load.
01
The levers interact
Solar may lower kWh without lowering the billed peak. A supply contract can change when capacity savings reach you. Every lever has to be priced against the others, not on its own.
02
Programs and peaks compete for the same battery
A ConnectedSolutions event and your own monthly peak can land on the same afternoon. Sometimes one discharge serves both; at other times, stored energy has to be reserved for competing needs.
03
The rates keep moving
Basic service resets monthly, delivery rates several times a year and program terms on multi-year plans. A plan built on last year’s bill drifts out of date.
Compare the cost after savings and program benefits
For facilities that fit, the right combination of rate options, demand management and eligible program benefits can reduce effective electricity costs by up to 30%, bringing them closer to the U.S. average. Actual results depend on your facility, contract and program eligibility.
Program revenue may arrive separately from the utility bill. Include the payments you keep, system costs and your ownership agreement when comparing the options. A lower effective cost does not change the utility’s published tariff.

Questions about lowering a Massachusetts electric bill
How can a business drastically lower its electric bill in Massachusetts?
There is no single trick that halves a commercial bill. The big savings come from combining levers that each work on a different part of it: efficiency for the kWh, a supply contract for the price, and demand management or a battery for the demand charge, plus program payments on top. Start by finding out how much of your bill is demand charges.
What are the most effective energy-saving strategies for commercial buildings?
Lighting and controls upgrades, variable-speed drives on fans and pumps, fixing compressed-air leaks and tuning HVAC schedules are the usual first steps, and Mass Save incentives cover part of many of them. For facilities with large demand charges, managing the monthly peak often matters as much as cutting kWh.
Does Mass Save help businesses?
Yes. Mass Save, run by the Massachusetts utilities, offers business assessments and incentives for efficiency projects such as lighting, HVAC, motors and controls. Check your utility, account eligibility and the approval requirements for each offer.
Is a competitive electricity supplier worth it for a Massachusetts business?
It can be, especially for large users exposed to variable winter basic service prices. Compare the all-in price over a full year, including capacity and transmission pass-throughs, usage bands and termination fees, not just the headline rate per kWh.
Does ConnectedSolutions pay businesses?
Yes. Eversource and National Grid customers can be paid for reducing load during summer grid peaks. National Grid publishes daily-dispatch incentives of up to $200 per kW per summer. Targeted dispatch has separate event and payment rules. Payments depend on measured performance, enrollment, applicable caps and provider fees.
Does solar lower demand charges?
It can, when solar is generating during the intervals that set your billed demand. A cloudy interval or a peak after sunset can limit the benefit. Solar mainly reduces purchased kWh; a battery can shift stored energy into peak intervals. Your load and tariff determine the result.
We run 24/7 with a flat load. Does a battery still help?
Less than for a peaky plant. A battery saves by cutting spikes above your normal load, and a truly flat load has few. It can still earn ConnectedSolutions payments in summer, so it is worth a look, but some round-the-clock facilities are not a fit, and we will say so.
Our shift ends at 4 pm. Don’t we already miss the peak hours?
Not for the demand charge. National Grid G-3 demand hours include 8 am to 9 pm on non-holiday weekdays, so a 9 am spike counts. Eversource demand hours depend on the tariff and service area. The late-afternoon hours matter more for ConnectedSolutions and Clean Peak, where an early finish can actually help.
Can a battery handle CNC machines, welders or presses?
Your machines keep running from the grid as they do today. A behind-the-meter battery connects at the facility’s service and covers part of the combined load when it rises above a target, so short, sharp loads are fine as long as the system is sized for the power they add.
Most of our energy is natural gas. Does this apply?
Only to the electric bill. A battery and demand management lower electric demand charges, not gas costs. If the electric bill is small, the saving will be too: the screen we use is facilities spending $10K+ a month on electricity.
We have a fixed-rate supply contract. Does that conflict?
No. A competitive supplier replaces only the supply charge. Delivery remains with Eversource or National Grid. A battery may reduce demand charges under that delivery tariff, while the fixed supply contract determines how any supply or capacity benefits reach you.
We are on a municipal light plant. Does this apply?
Partly. Municipal utilities set their own rates, and many still bill demand charges, so peak shaving can pay. ConnectedSolutions is for Eversource, National Grid and Unitil customers, and resources in municipal light plant territories are ineligible for Clean Peak certificates. Ask your municipal utility about its own programs instead.
How much can a battery cut my demand charge?
It depends on how peaky your load is, how long the peaks last and how well the battery is aimed at them. The useful number is the kW it can reliably take off your monthly peak, every month. A first-pass screen usually puts the overall saving at about 1–4 months of the electric bill a year, but it varies a lot by site. We work out the real number from a year of your 15-minute interval data.
