The Brooklyn Microgrid example begins with a correction that matters. Neighbors could agree to buy and sell energy through a digital transaction, but the electricity still traveled through Con Edison infrastructure. No specific electrons moved from one neighbor's roof to another neighbor's house.
Maggie Clout made that distinction in the 2018 Constructrr episode about microgrids, resilience, and local energy markets. The transaction could change who received a credit or debit. It could not replace the physical grid, the controls that balance supply and demand, or the people responsible for operating the system.
That separation gives an owner a better starting point. A market platform, an on-site generator, and a resilience plan may be connected, but they are not interchangeable.
A financial trade does not operate the microgrid
In the Brooklyn pilot, Maggie Clout described consumers and prosumers setting prices and settling local transactions. The platform also gave participants information about energy use, purchases, sales, and financial results. Con Edison still owned the distribution lines that carried the power.
The example places blockchain in a specific role. It can record and settle an agreement. It does not decide which loads are critical, keep generation and demand in balance, or determine when a site can safely separate from the utility.
Resilience depends on a complete operating system
When Maggie Clout defined a microgrid, she named three connected parts: on-site generation, loads that need service, and controls that keep those two sides balanced. The system also needs a utility interconnection and the ability to operate independently when it islands.
That definition changes the equipment conversation. A battery, solar array, turbine, or generator is one part of the system. The owner still has to know which loads the site must carry, what the controls will do, and how the system will behave when outside power is unavailable.
Maggie used high-rises, nursing homes, schools, campuses, and medical centers to show why those choices matter. During an extended outage, elevators, alarms, intercoms, lighting, communications, and other critical services may depend on the on-site system. She also said that not every building needs a microgrid. Site fit has to be established.
One set of assets, two operating days
The episode separates the business case into two conditions:
- During an outage, the system can support selected critical loads after separating from the utility grid.
- During what Maggie Clout called “normal blue sky days,” available assets may support demand response, local transactions, or other market activity.
Maggie called the second possibility “monetized idle assets.” She presented it as a way to make the financial case more attractive, not as a guaranteed revenue result. The site, market, control rights, and utility arrangement would still shape what is possible.
Agreement is part of the system
The physical and financial pieces cannot move on their own. Maggie Clout described public utility commissions, utilities, and regional system operators as groups that had to come on board for new market arrangements. She also said the work needed buy-in from different stakeholders. The Brooklyn example itself depended on utility infrastructure even while participants settled trades through a different platform.
For an owner, the first review can stay close to one property. Identify the critical loads, on-site generation, control system, utility connection, and people who would have to approve how the assets operate. Then separate the outage purpose from the normal-day use. Those answers may show that the property is a good candidate or that it is not ready for this operating model.
A credible resilience case explains how the system will carry the difficult day, what the same assets may do on an ordinary day, and who must agree before either plan can work.
