BESS in the Baltics: The 15-Minute Revenue Playbook

The Baltic power system has officially joined the Continental European grid, marking the end of the region's era as an "energy island." However, for investors, the most significant change is the new 15-minute trading resolution. By revealing price spikes that were previously averaged out in hourly blocks, this shift has increased arbitrage revenues for 2-hour batteries by 20% in the first weeks of implementation.

Our latest resource, The 15-Minute Revenue Playbook, provides a tactical manual for navigating this high-resolution market. We move beyond general overviews to outline specific "plays" for asset configuration, regional revenue stacking, and mFRR capacity optimization.

Key Insights from the Playbook:

• The Entry Window: Why projects entering in 2026 see IRRs of up to 16%, while those entering in 2029 face significantly longer payback periods.
• The 2-Hour Edge: Why lower Capex and high flexibility make 2-hour systems the "optimal trade-off" for current market conditions.
• Regional Strategy: Tailoring your revenue stack for Estonia, Latvia, and Lithuania based on recent ancillary price surges.
