Battery Energy Storage Systems (BESS) in Renewable Energy Systems
Value from flexibility: Optimising battery energy storage systems with energyPRO
What if your renewable energy project could do more than just sell electricity when the grid allows it?
What if excess wind and solar production could be transformed into a flexible, revenue generating asset that improves grid compliance, increases market participation, and significantly boosts project returns – not only for utilityscale projects, but also for industrial consumers seeking reliable, lowcost power?
energyPRO integrates BESS as a fully optimised component of the energy system. This use case highlights how energyPRO models, simulates, and optimizes BESS across diverse real-world applications including hybrid wind solar plants, constrained grid projects, multimarket optimisation, and industrial facilities.
The result:
Improved renewable utilisation, new revenue streams, and stronger business cases.

Why BESS matters
The rapid expansion of wind and solar power has introduced new challenges for energy systems worldwide:
Key challenges
Increasing curtailment due to grid limitations.
Volatile electricity prices across day-ahead and balancing markets decreasing the value of production from renewable assets.
Growing need for flexibility, dispatchability, and firm power delivery.
Battery Energy Storage Systems address these challenges by enabling energy shifting, peak shaving, market arbitrage, and multi-market participation. However, the value of BESS is highly sensitive to sizing, operational strategy, and market assumptions - making detailed optimisation essential.
Avoid guesswork with energyPRO
Without a comprehensive techno-economic modelling tool, BESS investments are often based on rules of thumb or static spreadsheets. This introduces significant financial risk. energyPRO provides a unified platform to:
1
Modelling
Model hybrid renewable systems with high temporal resolution.
2
Integration with windPRO
Easily integrate the detailed energy yield calculations from windPRO.
3
Optimisation
Optimise BESS capacity based on investment cost, lifetime, and discount rate.
4
Simulation
Simulate participation across multiple electricity markets.
5
Financial performance
Quantify financial performance using bankable KPIs such as NPV and payback time.

2. Hybrid energy system with multi-market BESS operation
A hybrid system consisting of wind and solar generation, both modelled using output time series derived from windPRO energy yield calculations.3. BESS for industrial application in India
A hybrid power system for a factory in India with a flat, 24/7 demand of 25 MW. The system includes on-site wind and solar generation, with energyPRO using real 2024 Indian spot market prices.
Round The Clock operation of a hybrid system
The webinar takes you through simulating a project designed to meet generic RTC-style (Round-The-Clock) tender requirements. It demonstrates how wind and solar production time series, integrated with Day-Ahead Market electricity prices and demand obligations, can be analysed to determine an optimal hybrid configuration.
