Battery storage has become one of the hottest topics in commercial real estate leasing, a key amenity and, increasingly, a top tenant ask in Class A buildings. What was barely on the radar five years ago has now emerged as a central negotiating point between sophisticated tenants and landlords.
Electricity has become a bellwether political issue across the country, and energy reliability is at the heart of the discussion. In jurisdictions like Maryland, where electricity generation shortfalls are well documented, battery storage is not just a sustainability measure, it is a business continuity imperative.
Many will recall the famous scene from the 1967 film The Graduate in which Dustin Hoffman’s character is told the secret of future economic success, “just one word .. plastics.” In 2025, the one word is now batteries.
PJM Interconnection, which manages the regional electric grid serving Maryland and much of the Mid Atlantic, has repeatedly warned that “rolling brownouts or blackouts are a possibility” and that the state faces “risks of electricity supply shortfalls during periods of more extreme conditions,” such as severe heat waves or cold snaps. These warnings are not theoretical; they were issued in 2025, now shaping how tenants view energy resilience in site selection and lease negotiations.
This is not a partisan political issue. “There’s some bad energy policies in some of our neighboring states ..,” Democrat Virginia Governor elect Abigail Spanberger said this Sunday on Face the Nation. “We have to be clear-eyed about the fact that we will have an energy crisis headed into the future.”
Energy Resilience
Tenants, especially those whose operations depend on uninterrupted power, not only hospitals, but also data driven enterprises, AI companies, financial institutions, and life sciences tenants, increasingly view on site battery storage as a critical feature, not to mention those that occupy any building with an elevator. These systems provide backup power during brownouts, grid outages, or severe weather events, ensuring business continuity when the public grid cannot.
Moreover, tenants are rejecting buildings where owners have agreed to participate in demand response programs with electric utilities.
Cost Management
Battery storage also offers clear economic benefits. Through “peak shaving” drawing stored electricity during periods of high demand tenants can dramatically reduce utility costs. Energy arbitrage, storing energy during off peak hours for use during peak times, provides another layer of cost optimization. These features allow tenants to manage their energy budgets with precision, particularly as utility rate structures become more dynamic.
Sustainability and Regulatory Drivers
The sustainability story is equally compelling. Businesses in some locales face mounting pressure to meet statutory carbon reduction benchmarks. Buildings that offer on site renewable energy, such as solar paired with battery storage, may enable tenants to meet those goals. In Maryland, the Building Energy Performance Standards (BEPS) and similar schemes require reductions in Scope 1 greenhouse gas emissions and total energy use. For many buildings, compliance is only achievable through the integration of renewable generation with battery storage systems.
At the same time, some governments are actually banning fossil fuel backup generators, including in Maryland, which has laws moving toward all electric buildings. In some jurisdictions, using natural gas, petroleum, or other fossil fuel backup systems is becoming unlawful even in extreme emergencies. That regulatory shift makes battery storage even more valuable as the sole viable form of on site energy resilience.
The Technology Behind the Trend
From Alessandro Volta’s 1800 “voltaic pile,” a stack of zinc and copper discs separated by brine soaked cloth, to today’s advanced lithium ion systems, battery technology has come a long way. Most commercial building installations today use lithium ion batteries, though other types such as large scale lead acid and flow batteries, exist.
The next generation is already here: solid state batteries. These offer higher energy density, improved safety (no flammable liquid electrolytes), and faster charging. Costs remain high, but are falling fast. In our own building, we have installed pilot solid state batteries sourced domestically, an important distinction in light of U.S. dependence on foreign critical minerals, child labor, and other ethical concerns that surround parts of the global battery supply chain.
At its core, a battery converts chemical energy into electrical energy through an electrochemical reaction between an anode (negative terminal), a cathode (positive terminal), and an electrolyte. In the built environment, batteries are transforming from small scale backup devices for computers and servers into building scale infrastructure.
A Real Estate Revolution
Significantly, in a recent survey by a global commercial real estate firm, battery storage ranked among the top five issues in U.S. lease negotiations for the first time ever. This is a major shift. As battery storage becomes standard in Class A buildings, the trend will inevitably cascade to other building classes, reshaping expectations across the market.
Even government buildings are in the mix. Many public sector facilities are subject to “demand response” mandates that require them to reduce energy use first during grid strain. Talked about scenarios include school and government office “brown outs,” temporarily, so private businesses and residences maintain reliable electricity without interruption.
The Broader Context
Electricity is essential to modern society, powering everything from healthcare systems to data centers to smartphones. Yet in Maryland, which already imports over 40% of its electricity from other PJM states, energy independence is a long way off. Battery storage is not merely an amenity; it is key short and mid term nonlinear progress to human innovation, if not survival.
Globally, batteries expand access to reliable electricity, combating poverty and improving quality of life. Here at home, they are already redefining what it means to occupy a quality commercial property with state of the art infrastructure and amenities.
While battery storage did not even make the top ten list of tenant concerns five years ago, today it is one of the most sought after features. And interestingly, another new top five issue is enhanced building security, a blog topic for another day.
For now, it is enough to say this: battery storage is no longer a futuristic option. It is a present day necessity, and the newest hallmark of thriving commercial real estate.
In 2025, the one word is batteries.
