How Energy Trading Platforms Work: Types, ETRM and Automation

An energy trading platform is software that takes a trader, utility or large energy buyer from a market price to a settled trade.

Before exchanges and trading platforms, most energy changed hands through long-term contracts and over-the-counter (OTC) deals. Negotiations were slow and prices were hard to compare. Long-term contracts such as PPAs are still common, but a trader or a large industrial buyer can now also see the market price, place an order and track settlement on one screen.

Platforms fall into two broad groups:

• Centralized platforms: exchanges and operators run by a single managing body, such as a power exchange. Every trade goes through the operator's rules, order book and clearing.
• Decentralized platforms: peer-to-peer (P2P) systems where participants trade energy directly with each other, without a traditional supplier in the middle.

An energy trading platform works in three stages: pre-trade analysis, trade execution and post-trade settlement.

Pre-trade: forecasts and price data

The first stage happens before any order is placed. The platform pulls in price feeds, weather data and demand or generation forecasts, so the trader knows how much energy to buy or sell and at what price it makes sense. For a portfolio with solar or wind assets, a wrong forecast means buying the missing volume later at a worse price.

Execution: day-ahead and intraday

The second stage is trading itself. On the day-ahead market, participants submit bids into a single daily auction for delivery the next day. On the continuous intraday market, they trade closer to delivery to correct their position as forecasts change. A platform connects to these markets, submits the orders and shows which ones were filled.

Post-trade: nominations, settlement and reporting

The third stage starts once a trade is done. The platform sends nominations (the delivery schedule) to the grid operator, settles the trade financially and prepares the reports that regulators require. It is the least visible part of trading, and its workload grows with every trade, because each one has to be reconciled.

There are four main types of energy trading platforms: power exchanges, broker and procurement platforms, in-house trading desk tools, and peer-to-peer platforms. The examples within each type are in no particular order.

• Power exchanges. What they do: run organized day-ahead and intraday markets with clearing. Who uses them: producers, suppliers, traders, large consumers. Examples: Nord Pool, EPEX SPOT, TGE (the Polish Power Exchange).
• Broker and procurement platforms. What they do: help companies source energy, compare offers and run tenders. Who uses them: utilities and corporate energy buyers. Example: Enel X runs its Energy Exchange platform for energy procurement.
• In-house trading desk tools. What they do: forecasting, position views, order routing and algorithmic trading built around one company's strategy. Who uses them: trading teams, aggregators, asset operators.
• Peer-to-peer platforms. What they do: match prosumers who have surplus energy with nearby buyers. Who uses them: households, energy communities, small producers. Example: Power Ledger.

Of these, Nord Pool shows how much a single exchange covers. It runs day-ahead trading, continuous intraday, intraday auctions, financial hedging, and clearing and settlement. In August 2026 it operated in 17 European countries (Nord Pool monthly report, August 2026).

The main features of an energy trading platform are market connectivity, forecasting, a live position, automated trading within limits, regulatory reporting and an audit trail.

• Market connectivity. Connections to the exchanges and intraday markets a company trades on, so orders go out and fills come back without anyone retyping them.
• Forecasting. Price, demand and generation forecasts that feed directly into bids.
• 15-minute resolution. Prices, bids, positions and settlement kept at 15-minute resolution end to end, not only on the trading screen.
• Position view. A live view of what the company holds, either built into the platform or synced with an ETRM system.
• Automated trading. Rules that place and adjust orders within limits set by a trader.
• Reporting. REMIT reports generated from trade data rather than assembled by hand.
• Audit trail. A record of who changed which order, when and why.
• Integrations. ERP for invoicing, an energy management system (EMS) for batteries and flexible assets, and SCADA, the control system that reports live plant data.
• Access control. Multi-factor authentication (MFA), encryption and access roles for every user.

Automated energy trading means software rules place and adjust orders on their own, inside volume, price and loss limits that a person sets.

Algorithmic trading applies the same idea to a whole strategy. The platform reads prices and forecasts, decides when to bid and how much, and sends the order without a trader clicking through each interval. It matters most on the continuous intraday market, where trading runs close to delivery and the position changes with every new forecast.

The trader still sets the limits, watches the exceptions and handles the trades the rules cannot price. Teams hesitate to hand large positions to an algorithm in a volatile market, and two things help: limits that stop trading the moment they are hit, and an audit trail that shows which rule placed which order and why.

The same logic runs on the asset side. Software that controls a battery can charge in the day-ahead or intraday price troughs and discharge at the peaks, with battery degradation counted as a cost in every cycle, or bid capacity into balancing markets.

An energy trading platform gives access to the market and executes trades, while ETRM software records those trades and manages position, risk, P&L and settlement.

ETRM (energy trading and risk management) software is the book of record. Large trading companies usually run both: the platform is where orders go out, and the ETRM system tells the risk team what the company owns, what it owes and how much it could lose. A company that only buys energy for its own use rarely needs either in full. It needs to track its contracts, open position and tranche purchases, which is the job of an energy procurement platform.

• Main job. Trading platform: market access and trade execution. ETRM software: trade capture, position, risk, P&L and settlement. Procurement platform: buying strategy, tranche purchases and supplier tenders.
• Main users. Trading platform: traders and dispatchers. ETRM software: risk, middle office, back office and finance. Procurement platform: energy buyers and their advisors.

Energize Capital notes that legacy ETRM systems struggle with growing data volumes, multi-commodity portfolios and compliance obligations (Energize Capital).

Three changes between 2024 and 2026 affect trading software in Europe: the 15-minute market time unit, REMIT II and fast-growing intraday trading.

15-minute market time unit

Since delivery day October 1, 2025, the European day-ahead market (Single Day-Ahead Coupling, SDAC) has used a 15-minute market time unit (MTU). That means 96 trading periods a day instead of 24. The switch was originally planned for June 11, 2025 (Market Coupling Steering Committee, September 12, 2025). For software, four times more periods means four times more prices to store, bids to build and positions to settle every day.

REMIT II

REMIT II, Regulation (EU) 2024/1106 amending the EU rules on wholesale energy market integrity and transparency (REMIT), entered into force on May 7, 2024 (URE). It covers more entities and products, shortens reporting deadlines and widens the definition of market manipulation. A new implementing regulation entered into force on April 29, 2026 (Baker McKenzie). With shorter deadlines, reports have to be generated directly from trading data.

Intraday growth

Trading is moving closer to delivery. Nord Pool's intraday markets reached a record monthly volume of 22.2 TWh in July 2026 (Nord Pool monthly report, July 2026). A continuous market with a 15-minute MTU is hard to trade by hand, so more of the routine work goes to automated rules.

Enerace.Online, which we have built since 2020 for the energy advisory Enerace, shows what a procurement platform does from day to day. Enerace helps companies buy electricity and gas.

• Portfolio position. Each client's position is worked out from the contracts entered in the platform. Before that, the calculations were done in spreadsheets.
• Tranche purchases. Clients could enter tranches in MW from 2021 and in MWh from 2022. Either way, the system shows each tranche as a share of the contract volume.
• Average-price tranches. Since 2022 the price of a tranche can follow the average quotation of a chosen product across a date range. For example: 50% of the volume priced at the average of the 2023 calendar-year baseload contract (BASE_Y-23 on TGE) between January 14 and October 30, 2022. The platform recalculates the average daily until the end date, and purchases entered before the averaging period do not count.
• Recommendations. A consultant recommends a purchase and gives the reason; the client approves it on the platform, and the history keeps who decided what.
• Tenders and invoices. Clients compare supplier offers in a tender module, which we built in three stages in 2024 and extended between September 2025 and January 2026. Since 2023 invoice control has checked invoice data against data from the distribution operator.

Enerace.Online turned Enerace's advisory service into a SaaS product for companies in Europe, and the SaaS model has brought Enerace new clients. Automating market data collection and recurring reports saves hundreds of hours each month, and the platform has a client management panel. The platform runs on Python, Django, GraphQL and React, hosted on AWS. The full story is in the Enerace case study.

The main barriers to adopting energy trading platforms are changing regulation, legacy systems, cybersecurity, trust in algorithms, missing skills and internal resistance.

• Changing regulation. Rules differ between countries and change over time. REMIT II took effect in 2024 and its implementing regulation followed in April 2026, so the reporting rules changed twice in two years.
• Legacy systems. Many utilities run older systems that do not integrate easily with modern platforms, and replacing them is expensive.
• Cybersecurity. The more a platform is connected to markets and assets, the larger the attack surface it has to protect.
• Trust in algorithms. Teams are slow to hand large positions to rules in a volatile market.
• Skills gap. Trading requires market knowledge that smaller companies often do not have in-house.
• Internal resistance. New tools change established processes, and people need time and training to adopt them.

Who uses energy trading platforms?

Energy trading platforms are used by power producers, energy suppliers, large companies that buy energy, aggregators and, on peer-to-peer platforms, prosumers. Each group uses a different type: producers and suppliers trade on exchanges, corporate buyers use procurement platforms, and prosumers sell surplus solar energy on P2P platforms.

Can energy trading be fully automated?

Not fully. Routine orders can run on rules, but a trader sets the limits, handles the exceptions and checks the audit trail.

Are energy trading platforms regulated?

Yes. In the EU, wholesale energy trading falls under REMIT II, in force since May 7, 2024, with a new implementing regulation in force since April 29, 2026. Market participants have to report their trades within the deadlines it sets.

What is peer-to-peer energy trading?

Peer-to-peer energy trading means participants trade energy directly with each other, without a traditional supplier in between. Power Ledger is one example. We cover the model in more detail in How P2P Energy Trading Is Energizing Our Future.

What is ETRM software used for?

ETRM software is used to record trades and manage position, risk, P&L and settlement. It is the book of record for the risk and back-office teams, while the trading platform handles market access and execution.

Why does the 15-minute market time unit matter for trading software?

Since October 1, 2025, the SDAC day-ahead market has had 96 trading periods a day instead of 24. Software has to store, forecast, bid and settle four times more intervals, so tasks that were manual at hourly resolution now need to be automated.
