KNESS to Add 55 MWh Storage for Latvia PV

  • KNESS Baltic secured 55MWh battery storage for Latvia’s growing solar fleet—absorbing midday excess, boosting evening supply, and delivering fast frequency response to stabilize the grid.

KNESS Baltic has been selected to supply 55 MWh of battery storage for solar parks in Latvia, a move aimed at improving flexibility as the country’s PV capacity grows. The project is designed to absorb excess solar output during periods of low demand and release energy during evening peaks, helping smooth variability in generation.

The batteries will also provide fast frequency response and reserve services to strengthen grid stability. Key factors include system integration—controls, telemetry and dispatch strategy—so the asset can participate effectively across multiple market services. The 55 MWh scale suggests battery storage is moving beyond pilot deployments toward repeatable installations linked to PV sites, potentially reducing curtailment and improving interconnection efficiency.

How will 55 MWh batteries from KNESS Baltic improve Latvia’s solar grid stability?

  • Store surplus PV generation when solar output exceeds demand, reducing the risk of curtailment at times when Latvia’s grids are most constrained
  • Discharge during evening and early-night demand peaks, helping match supply to load when solar falls off and improving overall daily energy balancing
  • Provide fast frequency support (e.g., response within seconds) to counter sudden generation/load changes that become more frequent as inverter-based solar grows
  • Offer reserve capacity for operators, improving reliability by giving the system a controllable source of power when conventional reserves are needed
  • Reduce ramping stress on the grid by smoothing the steep “duck curve” transition from late-afternoon solar decline to evening consumption
  • Improve grid flexibility and dispatchability of solar plants, making it easier for planners to integrate higher PV shares without proportionally increasing grid constraints
  • Lower volatility in short-term power flows by absorbing and injecting power on short time horizons, which can ease congestion in local distribution/transmission corridors
  • Enhance participation in multiple grid and market services through integrated controls, telemetry, and coordinated dispatch with Latvia’s grid operator requirements
  • Strengthen voltage and power-quality performance indirectly by supporting more stable active power output from connected PV sites during variability events
  • Increase confidence for further PV expansion by demonstrating a repeatable storage-to-PV model at 55 MWh scale, rather than relying solely on system-wide balancing resources
  • Improve interconnection efficiency by reducing the effective mismatch between PV output and available transmission capacity through time-shifting energy storage
