Commercial Battery-as-a-Service — Ontario first

Behind-the-meter storage for the commercial middle.

Turn peak electricity demand from an unpredictable operating cost into a controllable, optimizable energy asset. Electron Zero develops behind-the-meter battery systems that shave peaks automatically, lower electricity costs with zero or minimal upfront capital where financing permits, and monetize grid flexibility.

The problem

Peak demand is compounding. The grid is not keeping pace.

In North America, peak electricity demand is expected to grow materially over the next decade while generation, transmission and distribution expansion struggle to keep pace. The result is growing capacity pressure on the grid — and retail electricity costs rising faster than many commercial operators can comfortably absorb.

01

Capacity pressure is building

Peak demand across North America is expected to grow materially over the next decade while generation, transmission and distribution expansion struggle to keep pace. Retail electricity costs are rising faster than many commercial operators can comfortably absorb.

02

Electricity is now mission-critical

Greenhouses, machine shops, warehouses, cold storage and other commercial facilities increasingly treat electricity management as mission-critical to the operation — not a back-office utility line.

03

Ontario is the beachhead

Ontario commercial customers can face volatile bills and significant peak-related charges, where a single short-duration peak interval can materially affect the monthly bill.

04

The old playbook costs the business

Existing approaches often rely on manual load shedding or operational curtailment — forcing operators to choose between energy cost reduction and running the business normally.

05

The missing middle

Utility-scale and residential storage are scaling quickly, but the small-to-medium commercial segment remains an underserved middle — too large for residential products, too small for utility-scale developers.

06

A new revenue stack is opening

Falling battery costs, improved controls software and expanding utility and grid-service programs now let a single asset combine customer bill savings with grid-service revenue.

Distributed energy resources are part of the answer — and behind-the-meter batteries stand out. They are fast to deploy, modular, controllable, and increasingly economic.

The model

Commercial Battery-as-a-Service.

A battery on the customer's side of the meter, owned by capital that wants contracted cash flows, operated by software that never sleeps — and paid for out of the value it creates. The customer gets lower electricity costs without a capital project, a curtailment program, or a new job to do.

What Electron Zero does

  1. 01Identify suitable commercial and industrial customers
  2. 02Analyze interval load and tariff data
  3. 03Size the battery to the facility's load shape
  4. 04Structure the commercial agreement
  5. 05Manage engineering, permitting and interconnection
  6. 06Procure and integrate the system
  7. 07Coordinate project capital and financing
  8. 08Operate and optimize the asset through an EMS / software layer

Electron Zero acts as developer, integrator and optimizer — not necessarily the sole balance-sheet owner of every asset.

What the customer gets

  • Zero or minimal upfront capex where third-party financing is available
  • Automated peak shaving — no manual intervention
  • Reduced demand charges and peak-related electricity costs
  • No disruption to normal operations under normal use cases
  • Optional resilience value where appropriately designed
  • Participation in eligible demand-response, capacity, ancillary-service or grid-service programs
  • Predictable service payment, shared-savings or energy-services commercial structure

The value stack

Five revenue streams. One battery.

  1. 01

    Peak shaving

    Demand-charge avoidance — the core of the customer case.

  2. 02

    Energy arbitrage

    Where tariffs and price spreads support it.

  3. 03

    Demand response / capacity

    Where the customer and asset are eligible.

  4. 04

    Ancillary & grid services

    Where market access allows.

  5. 05

    Resilience value

    Avoided interruption, where relevant to the facility.

Not every project will access every revenue stream. Project economics depend on tariff, interval load shape, battery sizing, degradation, cycling strategy, market rules and financing.

Assumptions used

  • Suggested system 175 kW / 442 kWh nameplate (350 kWh usable after 90% DoD × 88% RTE)
  • Demand-charge value from implied site rate × dependable reduction; no demand ratchet modelled
  • Year-1 gross value $76,888, escalating 2%/yr, degrading 2%/yr over 15 years
  • O&M $2,431/yr (1% of gross CAPEX); NPV discounted at 8%
  • Pre-incentive CAPEX — credits and rebates would shorten payback

*Illustrative planning estimate only — not a savings guarantee, offer, financing commitment or investment recommendation. Under a Battery-as-a-Service structure, Electron Zero and asset capital carry the CAPEX; the customer benefit is typically delivered as a net position after a predictable service payment. Tax treatment, dispatch constraints, demand ratchets, peak-prediction accuracy, augmentation and actual tariff rules can materially change the result.

Class A vs Class B — the ICI decision

Class B customers pay Global Adjustment as a volumetric rate on every MWh they consume. Class A (ICI) participants instead pay through their Peak Demand Factor — their share of Ontario demand during the five coincident peak hours. For a facility that can curtail those peaks with a battery, the difference between the two classes is the decision.

Ontario tariff assumptions & methodology

What the inputs model

Demand-related share of bill
The slice of your bill driven by when you draw power, not how much — coincident-peak Global Adjustment for Class A, or demand / delivery line items for Class B. It is the only portion peak shaving can address; volumetric energy charges are largely unaffected by a battery.
Savings escalation (rate ramp)
Compounds the year-one savings estimate as utility rates and Global Adjustment costs rise over the analysis term. It models tariff drift over time — not growth in your facility's consumption.
Demand ratchets
Many tariffs bill a minimum demand tied to your highest recent peak (an 80–90% ratchet is common). Ratchet floors are not modelled here, so realizable Class B savings can be lower until ratchet windows reset — treat those results as an upper bound.
Peak coincidence & capture
Class A inputs. Coincidence is the share of your peak drawn during the five annual system peak hours — it sets your IESO Peak Demand Factor. Capture is the share of those peaks the battery is expected to catch; prediction accuracy is the key operational variable.
Facility load factor
Average demand ÷ peak demand. Converts peak kW into annual MWh so the Class B volumetric comparison draws from the same system-wide GA cost pool as the Class A calculation.

Methodology

  1. 01Sizing: suggested system ≈ 35% of peak demand at 2-hour duration; nameplate capacity derated by 90% depth-of-discharge × 88% round-trip efficiency.
  2. 02Class A (ICI): Peak Demand Factor = your top-5 peak-hour MWh ÷ system-wide top-5 MWh; annual Global Adjustment = PDF × total system-wide GA costs.
  3. 03Class B / other tariffs: dependable reduction (60% of battery kW) × implied site demand rate, derived from monthly spend × demand-related share.
  4. 04Value stack: peak value + demand-response / capacity programs ($45/kW-yr) + energy arbitrage ($25/kW-yr), scaled by facility-profile fit.
  5. 05Cash flows: savings compound at the escalation ramp, decline with degradation, less O&M; NPV discounts at the discount rate and IRR solves NPV = 0.
  6. 06Not modelled: demand ratchets, tax treatment, augmentation, exact tariff rules and peak-prediction misses beyond the capture slider — each can materially move the result.

Target customers

Built for the commercial middle.

The segments we design for are ideal customer profiles — not a representation of existing customers. What they share: material peak demand and favourable tariff and load characteristics.

01

Greenhouses & controlled-environment agriculture

High, climate-driven electrical loads with sharp coincident peaks.

02

Machine shops & light manufacturing

Process loads that spike against production schedules.

03

Warehouses & logistics

Material demand charges and growing on-site electrification.

04

Cold storage

Continuous refrigeration with costly peak coincidence.

05

Commercial buildings & multi-site portfolios

Repeated load profiles suited to standardized, portfolio-wide deployment.

06

EV fleet & depot charging

Strategic roadmap

Storage that lowers customer bills and strengthens the grid.

Every site is designed from day one to operate as part of something larger. Individual batteries become a coordinated portfolio; the portfolio becomes a grid resource. That is how site-level savings compound into system-level value.

01

Site BESS

Automated peak shaving and bill savings at individual facilities.

02

Portfolio aggregation

Many sites operated as one coordinated, software-managed portfolio.

03

VPP / DERMS layer

Flexibility orchestrated and dispatched as a single grid resource.

04

Utility / IESO / grid services

Capacity, demand-response and ancillary value at system scale.

Aggregation is a scalable roadmap objective, subject to market access and program rules — not a representation of an existing operating fleet. We begin in Ontario, expand across Canada, and extend into North America as the portfolio and market frameworks mature.

FAQ

The mechanics behind the savings.

Ontario's Global Adjustment, Peak Demand Factor and demand-response programs are the machinery this model is built on. The essentials, in plain terms.

Ask about your facility →
What is Global Adjustment (GA)?

Global Adjustment is a line item on Ontario electricity bills that covers the difference between market prices and the contracted and regulated costs of generation. Class B customers pay it as a volumetric rate on every MWh consumed. Class A customers pay it based on their Peak Demand Factor — which means controllable peak demand, not just total consumption, drives the charge.

What is the Peak Demand Factor (PDF)?

Your Peak Demand Factor is your facility's percentage contribution to system-wide consumption during the five highest-demand hours of the IESO base period (May 1 to April 30). Monthly GA charges through the following adjustment period equal your PDF multiplied by total monthly GA costs. Curtailing demand during those five hours directly lowers your PDF — and every GA bill that follows.

What is the Industrial Conservation Initiative (ICI)?

The ICI is the IESO program that allows eligible large electricity consumers to participate as Class A customers, with Global Adjustment charges set by their Peak Demand Factor rather than a volumetric rate. It rewards facilities that can reduce demand during provincial peaks. Eligibility thresholds, opt-in timing and base-period rules apply.

What is the difference between Class A and Class B?

Class B customers pay GA volumetrically — the charge scales with total energy consumed and cannot be managed through timing. Class A (ICI) customers pay through their Peak Demand Factor, so reducing demand during a handful of critical hours can materially reduce a full year of GA charges. For suitable facilities, the class decision is one of the largest levers on the electricity bill.

What is demand response and the capacity auction?

Ontario's capacity auction pays participating resources a recurring availability payment for being on standby to reduce demand during periods of grid stress. A behind-the-meter battery is well suited to this: it can respond instantly without disrupting operations, stacking capacity revenue on top of Global Adjustment savings.

How does a behind-the-meter battery reduce my bill?

The battery discharges during predicted peak hours, lowering the demand your facility draws from the grid at the moments that matter most. For Class A customers that means a lower Peak Demand Factor and lower GA charges; for Class B customers it means lower demand-related charges. Energy arbitrage and demand-response revenue can stack on top where program rules allow.

What does a site evaluation involve?

We analyze your interval meter data, tariff class and rate structure, model battery sizing and dispatch against your actual load profile, and return a structured assessment: expected savings ranges, system configuration, and the commercial structures available. The evaluation is a study, not a commitment.
