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

Forecast the day. Cut the deviation.

Built for how the Romanian market actually works — you bid into OPCOM's day-ahead (PZU) and intraday markets, and Transelectrica settles every deviation from your schedule. As renewables grow and imbalance cost stops being socialised, forecast accuracy becomes a direct profit lever.

The forecasting platform for Romanian renewables — a day-ahead production forecast that beats the ENTSO-E benchmark, tomorrow's DAM price with P10–P90 bands, and an intraday re-anchor that tightens your position. We tell you what to bid and when to move the battery, so the deviation doesn't become a cost.

Built on public ENTSO-E Transparency data (Transelectrica & OPCOM). Measured out-of-sample, not promises.

The pressure

Romania's market is tightening around the deviation

As renewables penetration rises and cost-socialisation shrinks, deviation risk lands more and more on the aggregator. Forecast accuracy stops being a nice-to-have and becomes a direct profit lever.

The forecasting platform

Sharper forecasts. Smaller deviations. Better-timed batteries.

Three forecasting products that attack market cost end to end — a day-ahead production forecast that beats the benchmark, next-day DAM price, and a battery signal, in one platform built for the Romanian market.

Production

Production — the accuracy edge

Our day-ahead production forecast, plus an intraday re-anchor as delivery nears. This is the accuracy that shrinks your deviation before you even bid.

  • Beats the ENTSO-E day-ahead benchmark by ~+39% (median, win-rate 70%), out-of-sample
  • Intraday re-anchor: ~+30% median improvement over our own day-ahead (live-proven, separate baseline)
  • Transparent track-record — judge it yourself
Price

Price — next-day DAM (PZU)

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

  • Mean error ~31 €/MWh on D+1, with P10–P90 bands
  • Built on public market data (ENTSO-E load/RES forecasts, coupled SDAC-neighbour prices)
  • Produced daily, in time for the SDAC / 4M coupling gate
Trade signal

Battery — time the arbitrage

When to charge and when to discharge along the price curve. Don't produce into negative prices — store at midday, sell in the evening.

  • Charge / discharge windows on the price forecast
  • Estimated arbitrage upside per day
  • Ready for the Romanian battery (BESS) market
In progress

Direct bidding into OPCOM — soon you'll place your day-ahead and intraday bids from inside 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 bids on OPCOM — day-ahead, intraday and balancing.

Wired to the exchange (OPCOM)

The forecast becomes a decision in every market

A PRE trades in three markets. The same forecast feeds all three — from the next-day price to the intraday deviation.

Day-ahead

DAM (PZU) — what 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 bid before day-ahead gate closure under SDAC / 4M Market Coupling.

+1 to +6 hours

Intraday — correct your position

As forecasts tighten, the intraday re-anchor tells you how much to buy or sell on OPCOM's intraday market (Piața Intrazilnică), shrinking your exposure to deviation.

Balancing / ISP

Balancing — cut the imbalance

The forecast-vs-production gap is what gets settled. We turn the forecast into a smaller deviation against your schedule — where Transelectrica's imbalance cost lands on the PRE.

Our edge

The day-ahead production forecast is our proven edge: it beats the ENTSO-E day-ahead benchmark by ~+39% (median, win-rate 70%, out-of-sample), and the DAM price forecast runs at ~31 €/MWh mean error with P10–P90 bands. Both are produced daily before day-ahead gate closure — in time to act on.

For aggregators / PREs (Balance-Responsible Parties)

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

In Romania every deviation from your schedule is settled by Transelectrica, and as cost-socialisation shrinks that cost lands on the PRE. We can't remove uncertainty. We can give you the sharpest production forecast — day-ahead and intraday — so the deviation you're settled on is as small as it can be, and show you exactly how accurate it has been.

In euros, not promises

Why the intraday re-anchor is worth it — measured

As delivery nears, our forecast tightens. Trading on the intraday re-anchor instead of the stale day-ahead schedule shrinks your deviation — and the deviation is what you're settled on. Measured out-of-sample, not a promise.

Day-ahead accuracy

+39%

Our day-ahead production forecast beats the ENTSO-E day-ahead benchmark by ~39% (median) over live days, win-rate 70%, out-of-sample — the accuracy that shrinks your deviation before you bid.

Intraday re-anchor

+30%

Closer to delivery, the intraday re-anchor improves the production forecast by a further ~30% (median), live-proven — so you correct your OPCOM intraday position and cut the imbalance Transelectrica settles.

Got a battery? On your own historical production we compute what charge-discharge arbitrage would have earned on the DAM price curve — the specific business case for your storage, not a national proxy.

Why Enerthium

Honest numbers a trader would respect

Measured

Not promises

Our forecast skill is scored out-of-sample on live data, day after day. We publish what it can do — and what it can't.

Public data

Verifiable

Everything starts from public sources — OPCOM, Transelectrica, ENTSO-E — numbers you can check yourself.

Day-ahead + intraday

One package

Next-day price and the intraday re-anchor 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 share of your profit, do route-to-market or PPAs, or 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

Stated up front, so you can decide before you commit:

  • Park list & capacity (MW)
  • Production history (from the meter)
  • Imbalance / settlement invoices
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 — to a live dashboard for your portfolio only. No waiting on email: log in and watch the forecasts update across every horizon. It's exactly the product a paying customer uses. For each park:

  • Per-park intraday nowcast — up to ~3 hours ahead
  • Next-day DAM price + P10–P90 bands
  • Imbalance direction + spike-risk signal (short/long, asymmetric cost)
  • Battery arbitrage window
  • Ramp & drop alerts, live
Request a meeting + NDA → Book a demo →
Setup (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 we talk

Romanian aggregators are looking for exactly this. We don't ask for trust — verify the accuracy of tomorrow's DAM price yourself, free. In return, we'd like 20 minutes to show you the whole platform.
