The carbon benefit of batteries: 2024 methodology

Executive Summary

  • This article explains the methodology behind Modo Energy’s estimate that GB battery storage will save 1.4 million tonnes of CO2 in 2024.
  • Marginal carbon intensity is used instead of average intensity to better reflect emissions savings from battery trading and dispatch.
  • Inertia management savings account for 30% of avoided emissions, as NESO lowers minimum inertia requirements from 140 to 120 GVAs.

Subscribers to Modo Energy’s Research will also find out:

  • How emissions savings from frequency response are calculated, including the role of Dynamic Containment Low.
  • Why battery-driven grid services improve gas plant efficiency, reducing system-wide carbon intensity.
  • The assumptions behind attributing emissions reductions to battery trading, frequency response, and inertia management.

Introduction

Battery energy storage systems are on track to save 1.4 million tonnes of CO2 in 2024. This offsets total power sector carbon emissions by 4%, double the figure from 2023.
