Marcus Garvey Apartments, a 625-unit affordable housing complex in Brooklyn, became one of New York City's first multifamily microgrids by combining a 479-kilowatt rooftop solar array, a 300-kilowatt battery, and a 400-kilowatt fuel cell into a system that can power the property whether or not the utility grid is running. The financial lesson outlasts the hardware: because all 32 buildings sit on a single master-metered utility account the owner controls, every dollar the system trims from the power bill flows to net operating income, and the local utility contributed more than $400,000 because the property sits in a grid-congested area where onsite power let Con Edison defer a substation upgrade. The project reached completion in 2017, and it remains a practical model for how onsite energy converts an operating expense into property value.
Key Facts at a Glance
Marcus Garvey Apartments is a 625-unit affordable housing complex across 32 buildings in Brownsville, Brooklyn, owned by L+M Development Partners.
The microgrid pairs a 479-kilowatt solar array on 22 of the 32 buildings with a 300-kilowatt, 1,200-kilowatt-hour battery and a 400-kilowatt fuel cell.
All 32 buildings are master-metered on one owner-controlled utility account, the structural feature that let the owner, rather than tenants, capture the savings.
The project drew more than $400,000 in state incentives and enrolled in Con Edison's Brooklyn Queens Demand Management program.
That program was designed to defer a roughly $1 billion substation upgrade, so the property's grid-congested location became a financial advantage.
The systems went in during a gut rehabilitation, when open walls lowered the cost of upgrading wiring and electrical equipment for onsite generation.
What Is a Microgrid, and Why Does It Matter to an Owner?
A microgrid is a local power system that generates and manages electricity on the property and can either run connected to the utility grid or disconnect and operate on its own, a capability engineers call islanding. At Marcus Garvey, the owner and its energy partner Bright Power combined three pieces into one system, according to the project case study: rooftop solar that generates power during the day, a battery that stores it for use when the sun is down or demand peaks, and a fuel cell, a device that converts natural gas into electricity through a chemical reaction and runs continuously as a steady base of onsite supply.
The value to an owner comes in two forms. The first is lower day-to-day energy cost, because power generated and stored on the property offsets electricity the owner would otherwise buy at retail rates. The second is continuity: when the surrounding grid goes dark, the system keeps the lights, elevators, heat, and water pumps running. For a residential property, that reliability is a tenant-retention asset and, after a major storm, a habitability safeguard. The complex is electrically heated, which raises the stakes on both cost and reliability, since heat and power draw from the same meter.
Why Was Master Metering the Financial Key?
Master metering is what let the owner capture the savings. In a master-metered property, the entire building or complex is billed on a single utility account the owner controls, and the owner pays the power bill directly. In a submetered property, each unit has its own meter and each tenant pays their own utility, so an owner who installs solar pays for the equipment while the tenants collect the lower bills. That mismatch, known as the split-incentive problem, is the single most common reason multifamily energy projects stall.
Marcus Garvey did not have that problem. With all 32 buildings on one owner-controlled account, every kilowatt-hour the microgrid produced or shifted reduced a bill the owner was already paying, so the savings landed directly in net operating income (NOI), the income a property keeps after operating expenses. That is the transferable point for any owner weighing onsite energy: the metering structure determines who benefits, and a master-metered property is the cleanest case for turning an energy investment into higher NOI.
How Did the Utility Help Pay for It?
Con Edison helped fund the project because the property sits in a part of its grid that was running short on capacity. The complex is in Brownsville, inside the zone Con Edison targeted through its Brooklyn Queens Demand Management program, a plan state regulators approved in 2014 to relieve overloaded substations, according to Con Edison program filings. Rather than build a new substation at a cost the utility estimated near $1 billion, Con Edison paid customers across the area to cut and shift demand using efficiency, storage, fuel cells, and similar onsite resources, an approach the industry calls a non-wires alternative because it substitutes distributed equipment for traditional grid construction.
For the owner, that reframed the property's location. A grid-congested address is usually a liability that slows new service and raises costs, yet here it made the property valuable to the utility, which is why Con Edison approached the developer to participate, as documented in a case study from the City University of New York's Smart Distributed Generation Hub. The project ultimately secured more than $400,000 in state incentives for the solar and battery systems, capital that shortened the payback and lowered the owner's net cost. Owners evaluating a site should check whether their utility runs a similar geographically targeted program, because in a constrained area the grid operator may share the cost of the very equipment that also lowers the owner's bill.
Why Did Timing the Work to a Renovation Cut the Cost?
Installing the systems during a full renovation sharply reduced the cost of the work. L+M acquired an aging complex and undertook a gut rehabilitation, and because contractors already had walls open and crews onsite, upgrading the wiring, distribution feeders, and electrical switchgear needed to support onsite generation cost far less than it would as a standalone retrofit. The lesson generalizes well beyond this property: the cheapest time to make a building ready for onsite energy is during a capital event that is already happening, whether a repositioning, a major systems replacement, or a roof project. An owner planning any of those should evaluate solar and storage in the same cycle, even if the equipment goes in later, so the expensive electrical groundwork is done once.
How Does This Translate to Value Today?
The value math is straightforward and it favors durable savings. A permanent reduction in operating cost raises NOI, and at a typical commercial capitalization rate, the yield a buyer accepts on a property's income, of 8 percent, every $1,000 of durable annual NOI improvement adds roughly $12,500 to asset value. Onsite energy is one of the few operating costs an owner can permanently lower through a one-time investment, and the case for it is strengthening as the equipment market matures: the United States installed a record 20.2 gigawatt-hours of energy storage in the second quarter of 2026, according to the Solar Energy Industries Association, with commercial and industrial installations rising as costs fall.
The applicability depends on the building. Master-metered properties capture the savings most directly, as Marcus Garvey did. Owners of submetered buildings can still benefit by placing solar and storage on common-area loads such as lobbies, hallways, elevators, and water systems that remain on the owner's account, or by structuring a tenant-billing arrangement that shares the value. The Marcus Garvey project completed in 2017, and its core moves still hold: control the meter, time the work to a renovation, and use utility and state programs to share the cost. Together they turn a property's power bill from a fixed drain into a line an owner can manage, and manage profitably.

Frequently Asked Questions
What makes a property a good candidate for a microgrid?
The strongest candidates are master-metered, so the owner captures the savings; sit in an area where the grid is constrained, which can unlock utility incentives; and have a renovation or major systems replacement already planned, which lowers the cost of the electrical work. A property that fits all three, as Marcus Garvey did, offers the cleanest path from investment to higher net operating income.
What is the difference between master-metered and submetered?
In a master-metered property, the whole building is on one utility account the owner controls and pays. In a submetered property, each unit is metered separately and tenants pay their own bills. The distinction decides who benefits from onsite energy: in a master-metered building the owner captures the savings directly, while in a submetered building the value has to be structured through common-area systems or a tenant-billing arrangement.
What is a non-wires alternative?
It is a utility program that pays customers to reduce or shift electricity demand using onsite equipment such as efficiency upgrades, batteries, and fuel cells, instead of building new grid infrastructure. Con Edison used this approach to defer a roughly $1 billion substation upgrade, and property owners in the targeted area could receive payments for hosting the equipment that also lowered their own bills.
Does an owner need a fuel cell to build a microgrid?
No. A microgrid can be built from solar and battery storage alone, and many are. Marcus Garvey added a fuel cell for a continuous base of onsite power, which suits an electrically heated property with steady demand, but the right mix depends on the building's load, budget, and resilience goals.
Is this only relevant to affordable housing?
No. Affordable housing was the setting here, but the mechanics apply to any multifamily or commercial property. The features that made it work, owner-controlled metering, a grid-constrained location, utility and state incentives, and renovation timing, are common across market-rate housing, mixed-use, and commercial assets.
