How it works

Three steps. Then the system runs on its own.

Connect your inverter cloud and set a minimum price. From then on, TokPirate watches IBEX prices, curtails and restarts your plant and sends the schedule to your trader. No hardware, no site visit.

  1. Connect your cloud

    Give us access to FusionSolar, iSolarCloud, SEMS Portal or your inverter’s own cloud. No technician on site.

  2. Set your minimum price

    Choose the price you won’t sell below – per plant or per individual inverter.

  3. The system takes over

    It stops and restarts production based on IBEX 15-minute prices and sends your trader the schedule the day before.

A day in the life

A day in the life of your solar plant

What happens from the moment next-day prices are published to the end of the delivery day – without you pressing a single button.

The day before delivery

Tomorrow · 96 intervals of 15 minutes Sample data

  1. once prices are published

    IBEX publishes tomorrow’s prices

    The IBEX day-ahead market sets a separate price for every 15-minute interval of the next day.

  2. for every interval

    The system builds a curtailment plan

    It compares each price with the minimum you set and marks every interval that falls below it – plant by plant.

  3. the day before delivery

    The schedule goes to your trader

    Your forecast schedule, with the planned curtailments built in, is sent to your trader automatically. They know in advance when the plant won’t produce.

Delivery day

IBEX price and output Sample data

  1. 11:15

    Curtailed just in time

    Before the first interval priced below your minimum – in this example, the first negative price – the system limits inverter output through the manufacturer’s cloud.

  2. 14:30

    Back on when the price recovers

    When an interval priced above your threshold begins, the limit is lifted and the plant produces again.

  3. every 5 minutes

    Profit after fees, kept current

    See what the plant has earned today net of balancing, grid access and administrative fees.

  4. in real time

    Alerts if a plant goes offline

    If a plant or inverter loses its connection to the cloud, you get a push notification and an e-mail so you can act straight away.

Safety

Safe for your inverters

Curtailment uses the same power-limiting function you could set by hand in the manufacturer’s app. Nothing is switched off at the breaker.

Inverter active power Sample data

  • The manufacturer’s standard function

    We use the active power limit built into the inverter and its cloud – the same setting you could apply by hand.

  • A smooth ramp, not a hard stop

    Output is ramped down and back up smoothly instead of the inverters being switched off abruptly.

  • No extra hardware

    No controllers, loggers or other devices to install. The plant only needs a working internet connection.

  • No site visit

    Connecting is done remotely, through the cloud your plant is already registered in.

Your part

What you do

Two things when you start. Everything else is the system’s job.

Set your minimum price

Choose the price below which the plant should not sell – for the whole plant or for each inverter. It can be 0 €/MWh or higher, for example if you also want your balancing and grid access fees covered.

The rest runs on its own

  • A curtailment plan for every 15-minute interval
  • A forecast schedule for your trader the day before
  • Curtailment and restart through the inverter cloud
  • Profit after fees and real-time alerts

FAQ

Questions about how it runs

More questions? See the full FAQ or write to us.

When exactly does the system curtail my plant?
Whenever the IBEX price for a 15-minute interval is below the minimum price you set. The plan is built the day before, once next-day prices are published. On the delivery day the system limits output in time for the start of that interval and lifts the limit as soon as the price is back above your threshold.
Will I be charged for imbalance while the plant is curtailed?
Curtailments are built into the forecast schedule your trader receives the day before, so they know about them in advance. The main source of imbalance remains weather forecast error – as for any solar plant. More in our guide to imbalance and balancing groups.
Do I need to do anything every day?
No. Once you have set your minimum price and told your trader, the curtailment plan, the schedule, curtailment and restart all run automatically. You get alerts if something is wrong and can check profit after fees whenever you like.
Do I need hardware or a technician on site?
No. TokPirate works through the inverter manufacturer’s cloud – for example FusionSolar, iSolarCloud or SEMS Portal. The plant only needs a working internet connection, and connecting is done remotely in minutes. See the supported inverters.
