managing generation portfolios has outgrown the tools built to run them

As wind, solar and battery portfolios expand across multiple markets, operators need a connected, real-time view of their assets and market positions to coordinate decisions

more markets. more decisions

The same MW can serve day-ahead, intraday, ancillary services or imbalance markets - and the best option changes as conditions change.
less time to act

Forecasting, trading and dispatch need to stay aligned as market conditions shift.
every leak matters

When margins tighten, outdated forecasts, delayed trades and avoidable imbalance all erode portfolio value.

ETOS connects live
asset data, forecasting, optimisation, trading, nomination, settlement and dispatch in one continuous loop.

the value leaks in the hand-offs between your systems

Each tool can work as intended on its own. The problem is what happens between them.

forecasting

The forecast ignores the battery’s live state of charge, so it recommends trades the asset cannot deliver.
trading

An outdated forecast leaves the portfolio exposed to avoidable imbalance.
dispatch

The trade reaches operations too late to schedule delivery across the available units.
settlement

By the time imbalance appears in settlement, the opportunity to manage it has passed.

ETOS connects the chain

The same live view of your assets informs optimisation and the dispatch that delivers the traded position.

every market decision affects the wider portfolio

Wind, solar and battery assets compete for capacity across multiple markets, each with different opportunities and constraints. ETOS evaluates these together to optimise portfolio revenues.

Live asset conditions, market signals and portfolio constraints feed into the next optimisation cycle.

ETOS in action

The wind drops. ETOS closes the gap before settlement does.

A realistic afternoon for a wind and battery portfolio. Illustrative example.

day ahead: sold ahead

Wind output is sold on the market based on the forecast.
earlier: charged at a low price

The battery is charged in a low-price period, planned for an evening sale.
15:00: a forecast miss

Wind output falls below the volume sold. The portfolio is short and exposed to imbalance prices.

ETOS weighs the options in real time. It evaluates the live asset state, updated forecasts, imbalance price outlook and risk limits.

decision

Two ways to close the gap

A-
Use the battery

Cover the shortfall with the battery, sacrificing some of its planned evening sale and using cycle life.
B-
Buy the shortfall

Buy energy on the intraday market to close the position, at the prevailing price.

ETOS evaluates both options

In this scenario, buying back the shortfall preserves the battery for its planned evening sale.

optimising across assets and markets

A trade that looks attractive on its own may not be the best option for the portfolio.

The decision depends on the current state of the assets, the market opportunities available and the constraints that apply.
