Solutions / Aggregation & Balancing

Balance Management at Portfolio Scale

We manage generation assets under our own aggregation and balancing responsible group structures, handling market operations and imbalances with a portfolio approach.

What we do

Imbalance is a manageable commercial line

Renewable output changes hour by hour, and every deviation from the scheduled programme is settled as imbalance. Frekans brings your plants together under a Balancing Responsible Group (BRG) and runs market participation, schedule notification and settlement on your behalf.

Our forecasting, trading and operations teams manage the full chain, from Day-Ahead Market (DAM) bids and Intraday Market (IDM) adjustments to imbalance costs and monthly settlement checks. You focus on running the plant; we take on the market-side operation.

Our aim is not only to provide market access, but to set the portfolio’s position right for every hour.

Why portfolio matters

A single plant's deviation is not the same as the deviation of a portfolio of assets with different generation profiles.

Frekans assesses each plant not only on its own, but by its effect within the portfolio.

Hydro

Flexible output driven by reservoir and flow, shiftable within the day.

Wind

Output driven by wind speed, with high hourly deviation.

Solar

A clear daily profile, with sudden short deviations from cloud cover.

Portfolio

When different profiles sit in one group, deviations partly offset each other and net imbalance shrinks.

Three components

The portfolio’s full market operation, from registration to settlement

Aggregation

We bring your plants into our portfolio and run the administrative and operational processes of market participation with EPİAŞ.

EPİAŞ registrations, settlement units and meter definitions
Joining and transferring into the Balancing Responsible Group
Collateral, market operation fees and invoicing
A single counterpart for EPİAŞ, TEİAŞ and distribution companies

Balancing

We update generation forecasts through the day and adjust the position on the IDM, reducing real-time imbalance and its cost.

Hourly plant-level forecasts with intraday updates
Final day-ahead generation schedule (KGÜP) notifications
IDM position adjustment and imbalance risk management
Hourly tracking of imbalance and KÜPST amounts

Portfolio Optimisation

We make commercial decisions on the portfolio’s net position rather than plant by plant, turning differences between assets into value.

Lower imbalance volume through netting within the portfolio
Using flexible assets such as hydro and batteries to offset deviations
Capturing spreads between DAM, IDM and balancing prices
Plant-level allocation of revenues and costs

How we work

A continuous cycle from day-ahead to settlement

Every delivery day is run with the same discipline. Forecasting, bidding, scheduling and settlement repeat every day, including weekends and public holidays.

D-1

Forecast and DAM bid

We forecast next-day hourly generation from weather models and plant data and submit the portfolio bid to the DAM.

D-1

Schedule notification

Based on DAM results, we prepare plant-level schedules and notify the system operator on time.

Intraday position management

We monitor updated forecasts and balancing instructions and adjust the position on the IDM when it pays.

D+1 / Month end

Settlement and reporting

We check meter data and settlement notices and report results plant by plant.

Active Balancing

We don't just report forecast changes.

When a new generation forecast comes in, we assess whether changing the market position makes economic sense.

Imbalance management is not a passive accounting task. It is an active trading function.

What you gain

Lower cost, more predictable revenue

Lower imbalance cost

Netting within the portfolio and intraday adjustments reduce the imbalance volume that gets settled.

More predictable cash flow

Imbalance costs fluctuate less, making budgeting and financing easier to plan.

One counterpart

Registration, scheduling, settlement and invoicing are run by one team.

Every day, every hour

Forecasts and positions are monitored continuously, including weekends and public holidays.

Transparent reporting

We report generation, deviation, imbalance cost and market revenue plant by plant.

Built to grow

New plants, hybrids and storage join the existing portfolio management through the same processes.

Frequently asked questions

About aggregation and balancing

Under the Balancing and Settlement Regulation, it is a structure that brings the balancing responsibility of several market participants under one party. Imbalances within the group are netted before settlement, and the group’s balancing responsible party is liable for the net imbalance.

Licence details, installed capacity, connection and meter details and historical generation data are enough for a preliminary assessment. We plan and run registration and transfer in line with the EPİAŞ calendar.

Yes. Plants under YEKDEM are also subject to forecasting, scheduling and imbalance obligations, and we apply the same forecasting and balancing processes to them.

Imbalance costs and the portfolio effect are allocated to plants using the method defined in the contract and reported plant by plant every settlement period.

Your existing bilateral contracts continue. Delivery obligations are included in the portfolio position and taken into account in balancing planning.

Market access. Trading. Optimisation.
