Grid-Interactive Buildings: $74B by 2035 — When the Controls Stack Becomes an Income Line
Artificial intelligence, onsite storage, and distributed energy management now let a commercial building manage money the way it once managed temperature.
By Keith Reynolds | Publisher & Editor, ChargedUp!
Grid-interactive buildings connect BAS, AI, storage, and DERMS so properties can shift load, shave peaks, and sell flexibility. Frost & Sullivan values the market at $18.57B in 2026 on route to $74.31B by 2035. LBNL finds up to 30% of peak load can move without tenant impact. New VPP tariffs and recent Google/Voltus and Leap/Verantum deals show the controls layer now earns money, not just manages temperature.
Key Takeaways
The controls stack converts a cost center into a flexibility asset, and energy-as-a-service contracts move the capital risk off the owner's balance sheet.
Regulation increasingly requires participation, as seen in the Illinois virtual power plant tariffs and a wave of large-load tariffs since 2018.
A building with integrated controls, onsite storage, and a documented flexibility revenue stream reads as lower risk to an acquirer.
For years, the building automation system answered to one master: the thermostat. Schedules were fixed, comfort was binary, and the utility bill arrived like weather. That habit is ending. The same controls layer now behaves like a trader with rules — responding to grid signals, prices, and risk — and it can create a new line of income without disrupting tenants. That’s a shift owners can measure in NOI and buyers can underwrite.
What is a grid-interactive building — in one sentence?
A property whose building automation system(BAS), onsite storage, and software can move or shed load in response to grid and price signals, turning energy management from a fixed schedule into a savings-and-revenue function.
How big is the market — and what’s driving it?
Market size: Frost & Sullivan values global grid-interactive building solutions at $18.57B in 2026, projecting $74.31B by 2035 (CAGR >16%).
Load flexibility: According to Lawrence Berkeley National Laboratory(LBNL), Up to 30% of commercial peak load can shift or shed with minimal tenant impact.
Program pull: Utilities and ISOs are paying for flexibility through demand response, VPPs, and new large-load tariffs.
Stack maturity: Vendors now contract to outcomes (savings and grid revenue), not just features, often as energy-as-a-service.
How does the controls stack actually work?
Think in four coordinated layers. These can be sourced from one provider or integrated across several:
Grid participation layer: Smart grid platforms (e.g., EnergyHub, Uplight, AutoGrid, Itron) connect building assets to utility/ISO programs and automate enrollment, dispatch, and settlement.
DERMS / microgrid control:Orchestrates onsite generation and storage; can island during outages to protect operations.
Storage optimization:Decides when to charge/discharge to capture demand charge avoidance, time-of-use arbitrage, and event revenue while protecting battery life.
Flexible-load management:Coordinates HVAC, ventilation, thermal mass, and high-load assets like EV charging to avoid peak collisions.
Packaging matters: outcome-guaranteed performance or EaaS contracts can move capital off the owner’s balance sheet and tie payment to delivered value — a decision a CFO can underwrite.
Which deals prove the model is live?
Google × Voltus (PJM, 100 MW): Voltus will assemble 100 MW of distributed flexibility across PJM, compensating homes and businesses that supply it.
Leap × Verantum (Dollar Tree portfolios): Leap and Verantum are enrolling connected commercial sites in CA, NY, and TX into automated demand response and grid services.
Both runs use the same engine: existing building controls, orchestrated by software, become a revenue-generating grid resource across different property types.
What policies are pushing buildings to participate?
Illinois VPP Tariffs (2026):Under the Clean and Reliable Grid Affordability Act, utilities filed VPP tariffs that must enroll customer-sited resources — explicitly including commercial BAS, batteries, and EV chargers — and pay when assets respond.
Large-load tariffs since 2018:Energy + Environmental Economics (E3) counts at least 38 large-load tariffs established since 2018, with 30 in 2025–2026.
Broader backdrop:ISO market rules and interoperability protocols (e.g., OpenADR) make automated participation repeatable across portfolios.
The direction of travel is clear: the building that can answer a grid signal becomes preferred — and the building that cannot becomes a stranded cost.
The Math Lands on Net Operating Income
For a property owner, the controls stack converts a cost center into a flexibility asset, and the arithmetic favors action. Every kilowatt of controllable load carries three potential returns: avoided demand charges during peaks, capacity payments for standing ready, and continuity during an outage that protects tenant operations. Each return lands on net operating income (NOI), and because commercial value is set by a capitalization rate applied to NOI, durable energy savings translate into equity.
Institutional buyers have started to price that durability. A building with integrated controls, onsite storage, and a documented flexibility revenue stream earns through volatility and reads as lower risk to an acquirer, which supports a resilience premium at sale. The owners who install and integrate the controls layer now will retain tenants who value bill stability, qualify for the utility and state programs that increasingly require it, and hold an asset that performs when the grid is stressed. The building that sits passive on the grid will increasingly look like the high-risk asset on the block, exposed to every rate increase and every outage with no offsetting line of income.

What is a grid-interactive building?
A building whose controls, storage, and software let it move or shed load in response to grid and price signals, turning energy management into a revenue and savings function rather than a fixed schedule.
How large is the grid-interactive building market?
Frost & Sullivan values it at $18.57 billion in 2026, on a path to $74.31 billion by 2035, served by a vendor ecosystem of roughly 130 companies selling demand response, DERMS, and AI optimization.
How does it affect net operating income?
Each kilowatt of controllable load carries three returns: avoided demand charges, capacity payments, and outage continuity, and because value is set by a cap rate applied to NOI, durable savings convert into equity and a resilience premium at sale.
