BESSview — the simulation platform behind Birdview Energy

Numbers you can defend in front of any investment committee

BESSview simulates and backtests standalone BESS, solar+storage and wind+storage revenues on real market data — hour by hour, market by market. No black box: every assumption is yours, every result is traceable.

Backtested on published market prices Day-ahead · Intraday · Imbalance · aFRR Grid restrictions & curtailment included

Live product footage — simulation & backtest results in BESSview

Built for the people who carry the risk

Whether you develop the asset or trade its output, the question is the same: what will this battery actually earn — and what can go wrong?

PV & BESS developers

Prove the business case before FID. Size the battery against your grid connection, test non-firm capacity (ATO/TDTR) scenarios, include subsidies and curtailment, and hand your investors a cashflow they can audit line by line.

  • Standalone, solar+storage and wind+storage
  • Grid congestion & non-firm connection modelling
  • IRR, NPV and financing structures built in

Traders & PPA providers

Quantify what a battery is worth under your trading strategy before you structure the PPA or tolling agreement. Backtest revenue stacking across day-ahead, intraday, imbalance and aFRR on real published prices — not on averages.

  • Multi-market revenue stacking, hour by hour
  • Backtests on historical market data
  • Trading constraints & strategy settings you control

These are unedited clips from BESSview. What you see is what you get.

Trust, verified

Backtest against the markets that actually happened

Forecasts are opinions; backtests are evidence. BESSview runs your exact asset configuration against published historical prices, so you can see what it would have earned — and compare that with the forward-looking simulation side by side.

  • Simulation and backtest, one screen
  • Net margin, revenue and charging cost per market
  • IRR, NPV, cycles and degradation per year
No black box

Drill into every dispatch decision, every hour

If a result surprises you, you can check it. Open any day and see exactly when the battery charged, which market it discharged into, at what price, and what the state of charge was — alongside the market prices that drove the decision.

  • Power & state of charge per market
  • Revenue by market throughout the day
  • Underlying price curves for full auditability
Your assumptions, not ours

Every parameter on the table — and under your control

Battery degradation, availability, inverter limits, subsidies, curtailment behaviour at negative prices, CAPEX and OPEX templates, loan structures, discount rates, trading constraints. Change any of them and rerun the scenario in minutes.

  • Guided setup: site, grid, battery, economics, trading
  • Financing: loans, interest, discount rate, energy tax
  • Reusable CAPEX/OPEX and expense templates
Bankable outputs

Cashflows your bank and investors can work with

Year-by-year cashflow over the full project lifetime, with revenue broken down per market, degradation applied, cycles counted and OPEX deducted. Export to Excel and drop it straight into your financial model or information memorandum.

  • Multi-year cashflow and revenue breakdown
  • Excel export and shareable reports
  • Lock scenarios to keep an audit trail
The whole site, not just the battery

Model your real location — solar, wind and grid included

Place your project on the map and describe it as it will actually be built: panel orientation and tilt, east–west or single orientation, inverter limits, wind turbines, and the grid connection that everything has to fit through.

  • Map-based location setup with real coordinates
  • Detailed PV configuration: layout, azimuth, tilt, inverter limit
  • Reuse locations across simulations and scenarios
Real weather, real constraints

Weather-based production profiles and grid restrictions

Generate PV production profiles from satellite irradiance and reanalysis weather data for your exact coordinates — or upload your own. Then add the constraint most tools ignore: non-firm grid capacity (ATO/TDTR) with time-dependent transport restrictions.

  • Location-specific PV profiles from weather data
  • Upload your own production profiles
  • Non-firm connection (ATO/TDTR) time blocks

Why professionals trust BESSview

A revenue model is only as good as your ability to check it. BESSview is built so that you never have to take our word for anything.

Evidence over promises

Every simulation can be backtested against real published market prices. If our model says it, you can verify it.

Transparent to the hour

Drill from annual IRR all the way down to a single hour of dispatch. No aggregated hand-waving, no hidden spreads.

Your data stays yours

Frequently asked questions

Straight answers, before you sign up.

BESSview is Birdview Energy's web platform for simulating and backtesting the revenues and project economics of battery energy storage — standalone or co-located with solar and wind. You define the asset, the grid connection, the economics and the trading strategy; BESSview computes hourly dispatch across multiple markets and turns it into IRR, NPV and year-by-year cashflows.
BESSview stacks revenues across day-ahead, intraday, imbalance and aFRR markets, with the Dutch market covered in depth. Want to model a project in another bidding zone? Talk to us — coverage is expanding.
A simulation projects your asset forward over the project lifetime using price scenarios. A backtest runs the same asset against actual historical market prices, hour by hour, showing what it would really have earned. BESSview shows both side by side — so you can judge how the forward-looking numbers relate to what markets have actually done.
Standalone BESS, solar+storage and wind+storage, in any size. You control battery power and capacity, degradation, availability, inverter limits, PV panel layout (including east–west), azimuth and tilt, and how solar-to-battery charging behaves — including behaviour during negative price hours.
Yes — this is one of BESSview's strengths. You can model non-firm grid capacity (ATO/TDTR) with time-dependent transport restrictions, so the dispatch respects the connection you actually have, not the one you wish you had. That matters enormously for project economics in congested grids.
Market prices come from published exchange and TSO data. PV production profiles are generated from satellite irradiance and reanalysis weather data for your exact coordinates — or you can upload your own measured or contracted profiles.
IRR (project and equity), NPV, net annual energy margin, revenue and charging cost per market, cycles per year, and a year-by-year cashflow with a full revenue breakdown. Everything can be exported to Excel or a shareable report for your investment committee, bank or counterparties.
You can be set up in one day. Defining a project takes minutes with the guided wizard, and scenario reruns take minutes rather than days — so testing a different battery size, grid limit or trading strategy is something you do over coffee, not over a week.
Yes. Your projects, locations and scenarios live in your own organisation's account, with user management and access control so you decide who in your team sees what. We do not share your project data with third parties.
Sign up at bessview.nl or book a demo and we'll walk you through the platform on your own project. Pricing depends on your team size and use case — we'll give you a clear quote after the demo, with no obligations.
