Power trading enables additional revenue through the targeted use of PV and storage on electricity markets — flexible, automated, and profit-oriented.
Power trading refers to the buying and selling of electrical energy on different markets — for example on power exchanges or through direct contracts. Companies, energy suppliers, and operators of energy assets (e.g. PV systems or Battery Energy Storage Systems (BESS)) trade electricity volumes in order to optimize prices, market flexibility, or security of supply.
Power trading takes place across different time horizons: long-term (futures market), short-term (day-ahead and intraday market), or even in real time (balancing services market).
Battery Energy Storage Systems (BESS 2) can buy electricity at low prices, store it temporarily, and sell it again at higher prices (arbitrage).
They can also respond to price signals by charging or discharging at the right time — either automatically via an Energy Management System (EMS) or through a trading partner.
• Arbitrage with BESS: charge electricity at low prices and discharge it at high prices
• Participation in day-ahead or intraday markets
• Marketing of flexibility through aggregators or Virtual Power Plants (VPP)
• Participation in grid services (e.g. balancing services)
• PPAs with direct marketing to industrial customers or via the exchange
• Market prices (€/MWh): highly volatile, depending on supply and demand
• Spread between charging and discharging time: basis for arbitrage profit
• Storage response time: the faster the system, the better for short-term markets
• Coordination with grid usage: compliance with technical requirements and feed-in limits
Power trading is a growing revenue stream for Battery Energy Storage Systems (BESS). By acting strategically on electricity markets, additional revenues can be generated — without requiring the company to manage trading activities itself.
