¶ Site Energy Storage · BESS

Does energy storage make sense for you — and if so, how?

Brightmerge first helps you decide if BESS makes sense for you — and if the numbers say yes, we size and prove the investment before you commit, then run your battery optimally every day across arbitrage, peak shaving and demand response. Decide, design, operate — for real estate, fleets, charging hubs and developers, on new or existing applications.

¶ 01 · Why it matters

First question: does BESS make sense for you?

The honest first answer is sometimes no — and knowing that early is worth a lot.
But if it's yes, two more questions follow: how big, and can it hit those numbers every day?
Brightmerge answers all three, with one model that runs from the go/no-go decision through daily operation.

Start here

Decide with the numbers

Find out whether storage actually pays for your site before you commit a dollar — an honest go/no-go grounded in your loads, tariffs and returns, not a spec sheet. If the answer is no, you've saved a fortune. If it's yes, everything below is the “how”.

Size it to the money

Right-size power and capacity to the returns and your load profile — not rules of thumb or the vendor's spec sheet.

Prove it's bankable

Model IRR, NPV and payback a lender or board will accept — before you commit a dollar to hardware.

Bank the value daily

Real-time dispatch that captures arbitrage, peak shaving and demand-response revenue — automatically, every cycle.

Protect the asset

Every charge and discharge is weighed against state of charge, cycle life and warranty — value today without spending tomorrow's health.

¶ 02 · From plan to operation

The same model, from decision to daily dispatch.

One continuous thread: design the battery and prove it pays, deploy it, then run it every day against that same case. The plan doesn't get handed off and forgotten — it becomes the live baseline the battery is measured against.

Act 1 · Design

Model & size

Simulate battery configurations against your loads, tariffs and solar — and prove IRR, NPV and payback before you commit.

Act 1 · Design

Deploy

Commission on new or existing hardware. The approved design case becomes the live performance baseline.

Act 2 · Operate

Dispatch

24/7 optimization decides charge, hold and discharge every cycle — across arbitrage, peak shaving and demand response.

Act 2 · Operate

Reconcile

Every action is measured against the design case and weighed against battery health, with alerts on drift.

¶ 03 · Three ways a battery pays

Savings first. Then revenue on top.

The same engine stacks every value a battery can capture — behind-the-meter savings first, then market and grid revenue when it's worth more than storing. You don't pick one; you get them all, prioritized automatically.

Behind the meter
· demand

Peak shaving

Discharge into demand peaks to cut demand charges — often the single largest line on a commercial energy bill.

Savings
Behind the meter
· energy

Energy arbitrage

Charge off-peak and on midday solar, discharge when energy is dear — buying low and using high, every day.

Savings
Front of meter
· program

Demand response

Enrolled capacity paid to respond to grid events — revenue for flexibility you already have on site.

Revenue
Front of meter
· market

Grid & ancillary services

Frequency, capacity and reactive-power markets — from the same battery, when interconnection allows.

Revenue

Illustrative only. Available value layers depend on your market, tariff and interconnection.

¶ 04 · Built for batteries

Energy-smart. Hardware-agnostic.

Battery-aware

State of charge & efficiency

Dispatch modeled on real round-trip efficiency and available energy — not nameplate.

Cycle-life & degradation

Every decision weighs value captured today against capacity lost over the asset's life.

Warranty-envelope aware

Stays inside depth-of-discharge, C-rate and throughput limits so the warranty holds.

Thermal & safety limits

Respects operating windows and safety constraints on every cycle.

Open to your hardware

Vendor-agnostic

Runs across OEM battery systems — new build or already installed, no rip-and-replace.

Multi-protocol

Standardized onboarding through a proxy-based asset interface.

SunSpec ModbusOpenADROCPI
Edge + cloud

Real-time control on-site; monitor and manage every battery from anywhere.

Pairs with solar & EV

Co-optimizes with on-site generation and charging when they share the meter.

Tied to the money

Live P&L vs. design case

Actual value tracked against the bankable case — not just kWh cycled.

Continuous value maximization

Every cycle targets the highest net value across savings and revenue.

Reporting & dashboards

Operations and finance views, with Power BI and Tableau integration.

¶ 05 · From one battery to a fleet

One battery, optimized. Every battery, orchestrated.

Brightmerge runs each battery to its own design case — then runs them together, so a fleet of batteries reaches value no single unit could capture alone.

Step 01 · Per battery

Each unit at its best

Every system dispatched to its own bankable case — highest net value, health-aware, tracked in real time.

Step 02 · Across sites

Fleet-level optimization

Coordinate dispatch and benchmark every battery you own, so the fleet reaches gains no single unit could on its own.

Step 03 · As one asset

An aggregated, optimized fleet

Your batteries operate as a single, optimized portfolio — managed centrally, ready for the grid.

↳ Next step · VPP

That aggregated fleet of batteries is exactly what qualifies for grid-services revenue — operate them together as a virtual power plant with Brightmerge VPP.
