The energy storage industry has grown from a niche technology into a foundational element of the modern grid. In the United States, utility scale battery capacity reached 43.6 GW by the end of 2025 after averaging 70 percent annual growth for three years, and operators plan roughly 54 GW more over the following two and a half years (EIA). Batteries were 28 percent of all planned 2026 capacity additions, second only to solar (EIA). Globally, BloombergNEF expected a record 94 GW, 247 GWh, of storage additions in 2025. Here are the trends shaping what comes next.
Continued cost declines
The cost curve that created this industry is still bending. BloombergNEF's annual survey measured average lithium ion pack prices at $108 per kWh in 2025, and packs for stationary storage specifically at about $70 per kWh, down 45 percent in a single year (BloombergNEF). Lithium iron phosphate chemistry now dominates utility scale storage, trading some energy density for lower cost and longer cycle life. On the system level, NREL's 2025 cost update benchmarks a four hour utility scale installation at $334 per kWh with further declines projected through 2050 (NREL cost projections).
The implication is simple: as costs fall, more use cases pencil, more projects get financed, and storage shifts from an exceptional addition to a standard component of grid infrastructure.
Longer duration storage
The industry is moving beyond the two to four hour lithium ion systems that dominate today's fleet. Grids with high renewable shares need to shift energy across days, which is a different technical problem. Iron air and flow batteries, compressed air, thermal storage, and hydrogen are all competing for that role, and the U.S. Department of Energy has set a target of 90 percent cost reduction by 2030 for storage technologies that deliver ten hours or longer (Department of Energy).
For software, longer duration means the optimization horizon stretches from hours to days, and an EMS must be chemistry agnostic: the dispatch problem is the same shape whether the energy sits in lithium, iron, or heat.
AI powered operations
Artificial intelligence is moving from pilot to production in storage operations, in four practical forms:
- Predictive dispatch: models forecast load, solar, and prices so the battery positions itself hours or days ahead
- Anomaly detection: machine learning flags equipment behavior that precedes failures
- Degradation optimization: algorithms weigh battery wear against revenue on every cycle, extending useful life
- Market strategy: price forecasting sharpens bids in energy and ancillary markets
These are the capabilities behind the capture rate differences discussed in our guide to choosing an energy management system.
Virtual power plants
Aggregating thousands of distributed batteries into virtual power plants lets them collectively provide services that once required central plants. The Department of Energy's Liftoff analysis targets 80 to 160 GW of VPPs by 2030, worth roughly $10 billion a year in avoided grid costs (Department of Energy), and tracked United States capacity reached 37.5 GW in 2025 (Wood Mackenzie). The regulatory foundation is in place: FERC Order 2222 requires wholesale markets to accept distributed resource aggregations (FERC Order 2222).
Grid modernization and market reform
Market rules are catching up with the physics. Order 2222 opened wholesale markets to aggregations; interconnection reform under FERC Order 2023 moved queues to a first ready, first served cluster process to clear the backlog of projects, the large majority of which are now solar, storage, and hybrids (FERC Order 2023). Hybrid participation models, storage as transmission, and evolving ancillary products keep adding ways for batteries to earn, which our revenue stacking guide covers in detail.
Co located and hybrid systems
Pairing storage with solar or wind is becoming the default for new projects: hybrids share interconnection infrastructure, reduce curtailment, firm renewable output, and capture higher value products. Lawrence Berkeley National Laboratory's queue research shows hybrids now make up about half of proposed storage capacity waiting for interconnection (Lawrence Berkeley National Laboratory). The EMS for these plants must jointly optimize the renewable and the battery as one resource, which is how Intellect Operate treats them.
The software layer becomes the differentiator
As storage hardware commoditizes, the differentiator shifts to software: the EMS, the monitoring platform, and the optimization algorithms that determine how much value an asset actually captures. Two identical batteries in the same market can produce very different returns based solely on their controls, which is why the industry conversation is moving from cost per kWh to capture rate.
WATTMORE is building the software infrastructure for that future: Intellect Operate for real time dispatch, Intellect PPC for grid compliance, Intellect EnFORM for monitoring and data acquisition, and Intellect PLAN for sizing and financial modeling. Talk to us about your next storage project.
