Power futures: how a wind farm gets its loan approved

Power futures are forward contracts on electricity, traded on financial exchanges (Nasdaq Commodities, EEX) and OTC, that lock in a delivery price for a specific bidding zone and time block weeks to years ahead. They're how a wind farm gets its loan approved: the bank doesn't lend €100M against spot-market volatility, it lends against a 5-year future struck at €60/MWh.
A wind farm developer signs a 15-year loan to build 200 MW of capacity. The bank wants to know what the electricity will sell for in 2031. Nobody knows. But somebody on the Nordic forward market will quote you a price today for delivery in 2031, and that quote is what makes the loan financeable.
Power futures are forward contracts on electricity, traded on financial exchanges. They let a buyer fix a price now for delivery weeks, months, quarters, or years ahead. They are the main tool utilities, industrial consumers, and renewable developers use to manage price risk against the volatile spot market.
Two venues dominate Europe. Euronext Nord Pool Power Futures runs the Nordic and Baltic contracts after absorbing Nasdaq Commodities’ Nordic power-futures business through the 2025–2026 migration. EEX in Leipzig handles the bulk of continental volume. Most contracts settle financially: at expiry, the contract pays the difference between the strike price and the average day-ahead spot price over the delivery period. No electrons change hands. The buyer and seller exchange cash against the day-ahead reference.
Contracts come in monthly, quarterly, and yearly tenors, with some weekly products. The Nordic market also trades EPADs (Electricity Price Area Differentials), which hedge the basis between the Nordic system price and a specific bidding zone. If you want to lock in Estonia-zone exposure rather than generic Nordic, you need both a system-price future and an Estonian EPAD. That two-leg structure is awkward, and the EPAD leg is where Baltic liquidity gets thin.
Thin liquidity is not a footnote, it is a real cost. Wider bid-ask spreads on Estonian forwards mean a hedger pays more to transfer risk than a German counterpart does. Estonian EPADs were already suspended on the Nasdaq venue ahead of the Euronext migration, so whether liquidity returns under the new operator is one of the open questions for the Baltic forward market. This is one of the genuine economic gaps between the Baltic and continental markets, and it shows up in the price of long-dated commercial offers.
It is worth contrasting futures with PPAs. A PPA is a bilateral contract, often 10 to 15 years, frequently tied to a specific generator. A future is exchange-traded, anonymous, and rarely longer than three or four years out. Both lock in a price. The difference is mostly counterparty risk and tenor: a future clears through an exchange, a PPA depends on whoever signed it still being solvent in 2038.
The financial-versus-physical distinction sounds like technical plumbing, but it determines who gets paid in a price spike. When the spot hit four-digit euros per MWh in 2022, every financially settled future suddenly had a winner and a loser, and the cash moved through clearinghouses, not through wires. The forward curve is, in effect, the market consensus on what the next several years of spot prices will look like, repriced every trading day.
Volton trades day-ahead and intraday on Nord Pool for our portfolio rather than running a futures book. Power futures are mostly the domain of utilities, banks, and large industrial offtakers. But the forward curve still matters to us because it is the price reference that backs any longer-dated commercial offer a customer asks about. We operate downstream of it, not on it.

What is a Balance Service Provider (BSP)?
A BSP is a market participant certified by the TSO to deliver balancing services — frequency reserves like FCR, aFRR and mFRR. Here is how the role works in Europe and Estonia, and where aggregators fit in.
Inside Nord Pool
Nord Pool clears the day-ahead and intraday markets across the Nordics, Baltics, and much of Western Europe. We unpack the auction, market coupling, and what it takes to be a member.
Balance Responsible Party (BRP): who pays for every imbalanced kilowatt-hour
Every kilowatt-hour on the grid has a Balance Responsible Party that is contractually accountable for it. Here is how the BRP regime works under Elering and why aggregation matters.
REMIT Article 15 and the algorithmic-trading notification
REMIT Article 15 brings algorithmic energy trading under ACER oversight. We explain the notification regime, what counts as algorithmic, and why this matters for asset owners.
Day-ahead market: pricing an hour that has not happened yet
Every day at noon CET, an algorithm sets the price of electricity for every hour of tomorrow. The day-ahead auction is the reference the rest of the energy industry hangs off.
Intraday market — after the auction, reality drifts
After the noon auction closes, intraday opens — a continuous order book that runs until close to delivery. It is where flexibility actually pays.
PPAs — how long-term contracts financed the renewable boom
Power Purchase Agreements are 5–15 year bilateral contracts between renewable generators and corporate offtakers. They probably did more for Europe’s energy transition than any subsidy.
FCR: what catches the grid when a reactor trips
Frequency Containment Reserve activates within 30 seconds of a frequency deviation, fully automatic, no TSO signal. Batteries dominate it. It is what made grid-scale storage economically viable.
aFRR, the reserve in the middle
Automatic Frequency Restoration Reserve activates in ~30 seconds via TSO control signal, follows it on a 4-second cycle, and pulls the grid back to 50 Hz. PICASSO is quietly transforming the market.
mFRR — where Estonian battery profits come from
Manual Frequency Restoration Reserve is activated by a human operator, with full delivery in 12.5 minutes. In Estonia, it is currently the most lucrative balancing market for batteries.
