Advanced storage and digital grids turn intermittent renewables into dependable, accountable power.

Storage moves to the center of ESG-aligned power procurement

Corporate buyers are rapidly increasing their use of renewable power purchase agreements and on-site generation. Still, investors and regulators are demanding proof that decarbonization claims truly reflect hour-by-hour consumption. Energy-intensive sectors and hyperscale data center operators are pursuing “24/7 carbon-free” power, which is practical only when renewable generation is tightly integrated with energy storage and flexible grid operations.

Industry outlooks now highlight battery energy storage systems as the fastest bridge to firm, low-carbon power in the near term, while longer-duration technologies such as advanced flow batteries, thermal storage and hydrogen solutions mature. WTW

Battery storage as ESG infrastructure

Commercial and utility-scale battery storage projects are increasingly framed as ESG investments rather than purely operational assets. A surge in deployments since 2024 has been driven by technology cost declines, supportive regulation and the need for resilience against extreme weather events and grid congestion. Morgan Lewis

For corporates, on-site battery systems allow facilities to shift loads, shave peaks and ride through outages while aligning their consumption with periods of renewable generation. Insurers and risk advisors emphasize that storage can reduce both business interruption risk and exposure to volatile power prices exacerbated by climate-driven supply shocks. WTW

Smart grids as the digital nervous system of decarbonization

Storage alone cannot deliver ESG-aligned power without modernized, intelligent grids. Smart grids use digital sensors, automation and advanced analytics to balance supply and demand in real time, integrate distributed generation and enable new flexibility services. International agencies and consulting firms stress that grid modernization and expansion are bottlenecks for clean-energy deployment, and therefore critical to achieving climate targets.

Smart-metering, dynamic tariffs and demand-response programs can also provide granular data for ESG reporting, allowing organizations to track the emissions intensity of electricity at specific times and locations. Combined with storage, this enables genuinely time-matched low-carbon consumption claims rather than annualized averages. KPMG

Social and governance dimensions of the new grid

The “S” and “G” in ESG are increasingly part of grid modernization debates. Policymakers are under pressure to ensure that clean-energy infrastructure, including storage and transmission lines, is deployed in ways that are equitable, respectful of communities and transparent in decision-making. Concerns about land use, environmental justice and ratepayer impacts are driving new engagement models and governance requirements. The Department of Energy’s Energy.gov

For companies, participation in grid-services markets and flexibility programs comes with responsibilities around data privacy, cyber-security and fair treatment of smaller customers and prosumers. Boards are beginning to view energy strategy as a governance issue that touches everything from climate commitments to digital risk management.

Closing thoughts and looking forward

By 2026, advanced storage and smart grids will be the infrastructure layer that determines whether ESG climate commitments are credible. Organizations that actively participate in grid modernization—through investment, advocacy and innovative contracting—will have more options to secure reliable, verifiable low-carbon power. Those that treat the grid as an externality may struggle with physical constraints, regulatory delays and reputational risk around the integrity of their decarbonization claims.

The next ESG frontier in this space will be transparency: publishing time-stamped data on the carbon intensity of electricity consumption, documenting participation in flexibility and resilience programs, and showing how energy strategies support not only net-zero goals but also affordability, equity and system stability.
