Forecasting software for Bulgaria · Day-ahead · Intraday · Deviations

Forecast the output. Cut the deviation.

Built for the Bulgarian balancing-group reality — the renewables share keeps climbing, midday prices collapse, and every deviation between your schedule and your actual output is settled against your balancing group. We build on how the market here actually works.

The forecasting platform for Bulgarian renewables — day-ahead production and IBEX price for tomorrow, intraday position updates and P10–P90 bands. Our day-ahead output forecast beats the ENTSO-E benchmark by +39.7% (median over live days, out-of-sample), so your schedule is tighter before the gate.

Built on live IBEX & ESO data. Measured, not promised.

The problem

Deviation risk is landing on the aggregator

As the renewables share climbs and cost-socialisation shrinks, the risk of deviating from your schedule falls increasingly on the balancing group. Forecast accuracy becomes a direct lever on profitability.

Rising
Renewables share on the grid
more solar and wind on the Bulgarian system every year
More
Low & negative-price hours
midday price collapse spreading across SDAC-coupled markets
Growing
Curtailment risk
surplus renewables curtailed when the grid is long
On you
Imbalance risk shifts to the aggregator
as cost-socialisation shrinks, every deviation is settled against you

The forecasting platform

Forecast sharper. Cut the deviation. Time the battery.

Three forecasting products that solve the market cost end to end — day-ahead accuracy, DAM price, and a battery signal, in one platform built for the Bulgarian energy exchange.

Measured

Accuracy — day-ahead output

Our day-ahead production forecast beats the ENTSO-E day-ahead benchmark, so your schedule is tighter before the gate and less of it is settled as imbalance.

  • +39.7% better than the ENTSO-E benchmark (median over live days)
  • 77% win-rate, measured out-of-sample
  • Per-park intraday updates — satellite nowcast, in rollout (trial-measured)
Product

Price — next-day DAM

Tomorrow's IBEX day-ahead curve, produced before the gate. Where the price collapses at midday and where it peaks in the evening.

  • Mean error (MAE) ~22.5 €/MWh · with P10–P90 bands
  • Built on public data (ENTSO-E load & RES forecasts, coupled/neighbouring prices — RO, GR, HU, RS — and own-price recency)
  • Transparent track-record — judge it for yourself
Trade signal

Battery — time the arbitrage

When to buy and when to sell along the price curve. Don't generate into the negative — store at midday, sell in the evening.

  • Charge / discharge windows on the price forecast
  • Estimated arbitrage margin per day
  • Ready for the Bulgarian storage market (BESS)
In progress

Direct order submission to IBEX — soon you'll place your day-ahead and intraday orders straight from the platform, driven by the forecast. In active development.

One flow, from forecast to market

From forecast to bid — and you win it in the market

The forecasting system feeds the aggregator DAM price, production and deviations; you turn the forecast into orders on IBEX — in the day-ahead, intraday and balancing segments.

The forecast becomes a decision in every market

An aggregator trades across three segments. The same forecast feeds all three — from tomorrow's price to the intraday deviation.

Next day

Day-ahead — how much to bid

Tomorrow's price curve shows where the price collapses at midday and where it peaks in the evening, so you can shape your IBEX day-ahead order before the gate.

+1 to +6 hours

Intraday — correct your position

Once the per-park nowcast is live (in rollout for Bulgaria), the intraday production estimate will tell you how much to buy or sell on the IBEX intraday auctions and the continuous SIDC market, to shrink your deviation.

Imbalance settlement

Balancing — cut your imbalance cost

The deviation between your schedule and your actual output is what gets settled against your balancing group. Sharper forecasts and intraday updates keep that gap small — so less volume is settled at the imbalance price.

Our edge

Our day-ahead production forecast is production-grade: it beats the ENTSO-E day-ahead benchmark by +39.7% (median over live days, 77% win-rate, out-of-sample). The DAM price forecast runs at ~22.5 €/MWh mean error with P10–P90 bands, built on public market data (ENTSO-E load & RES forecasts and coupled/neighbouring market prices). Both are produced daily before the day-ahead gate — in time to act on.

For aggregators & balancing-group coordinators

You carry the imbalance today. We give you the forecast.

Every deviation between your schedule and your actual output is settled against your balancing group. We can't remove the uncertainty. We can give you a sharper day-ahead position — measured +39.7% better than the ENTSO-E benchmark, out-of-sample — plus per-park intraday updates (in rollout for Bulgaria) to show how much to correct.

We don't quote a national savings figure.
Your data
is the only honest benchmark
If you share your settlement statements, we measure — offline — the euro impact of tighter forecasts on your own imbalance settlement (a conservative upper bound, never a guarantee). Bulgaria's imbalance economics are less openly published, so we work from your numbers, not a national proxy.
In euros, not promises

Why intraday is worth it — measured on your data

Intraday forecasts tighten as delivery approaches, shrinking the gap that gets settled as imbalance. We quantify the reduction on your own historical output — conservative assumptions, measured for your portfolio, never a blanket guarantee.

Forecast error

Tighter

Production error shrinks from day-ahead to intraday as the forecast sharpens toward delivery — by how much, we measure on your parks with a per-park nowcast.

Imbalance cost

Lower

Less deviation means less volume settled at the imbalance price. We estimate the euro reduction on your own historical output — a conservative upper bound, measured for your portfolio, not a guarantee.

Got a battery? On your own historical output we compute how much charge-discharge arbitrage would have earned against the DAM price curve — the specific business case for your storage.

Public data

Verifiable

Everything starts from public sources — IBEX (БНЕБ), ESO, ENTSO-E — numbers you can check yourself.

DAM + deviation

One package

Next-day price and intraday correction under one roof — the knowledge and the way to act on it in the market.

Neutral

We arm you — we don't become your competitor

We don't take a cut of your profit, we don't do route-to-market or PPAs, we don't represent generation. Your forecast provider shouldn't work for your biggest competitor.

Test us on your own data

Put us to the test — on your own portfolio

Here's exactly what we need and what you get back — proven live on tomorrow, not the past. You decide first, then ask for a meeting.

1

What we'll need

Declared up front, so you can decide before committing:

  • Park list & capacity (MW)
  • Historical output (metered)
  • Imbalance settlement statements
2

Meeting + NDA

If it fits, you ask for a meeting. We sign a mutual NDA first — your data is protected and used only for your forecast, nothing else.

3

Live trial — your own login

We train on your data (~2–3 days) and give you your own secure login — credentials that expire after 72 hours — on a live dashboard for your portfolio only. No waiting for email: you log in and watch the forecasts update, exploring every horizon. It's the same dashboard a paying customer uses — for Bulgaria the day-ahead bid, DAM price bands and battery arbitrage are live today, with per-park intraday/nowcast in rollout. For each park:

  • Intraday production view — satellite nowcast (in rollout)
  • Tomorrow's DAM price + P10–P90 bands
  • Deviation-volume awareness (imbalance-€ via your settlement data, offline)
  • Battery arbitrage window (declared battery/hybrid)
  • Ramp & drop alerts (per-park nowcast in rollout)
Request a meeting + NDA → Book a demo →
Preparation (NDA + training) takes a few days; then your login is live for 72 hours, free — the same dashboard a paying customer uses, with every forecast produced in seconds. After the trial it simply continues as the paid service.

Check our credibility — then let's talk

Bulgarian aggregators are looking for exactly this. We're not asking for trust — verify the accuracy of tomorrow's DAM price yourself, free. In return, we'd love 20 minutes to show you the whole platform.
