2. Lab goals
To understand the present and future impact of microgrids, it ought to understand
the current regulatory, market and business structure of the power industry and
project with reasonable certainty its future. While we will not be able to predict
exactly how the future would look like, we must develop strategies that would allow
us to migrate from where we are today.
Starting from a generic Business models definition, this lab theme is aimed at
finding the more appealing and sustainable business model for the proposition of
microgrid.
– It will start with a complete assessment of the current Italian regulations
finding the more effective tools and models to address innovative project
with the Public Administration and private customers.
– Finally the resulting models might be “mapped” to the sponsor industries
solutions and might steer their strategy in successive roadmaps

3. What is a microgrid
3
A large number of microgrid definitions exist from industry, government, and academia. The closest to a U.S.
Government–approved microgrid definition is that developed by the Department of Energy (DOE) Microgrid
Exchange Group:
“A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical
boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and
disconnect from the grid to enable it to operate in both grid-connected and island-mode[*].”
We got three major messages delivered from this definition:
• Integration platform for supply-side (micro-generators) and demand-side resources (storage units and
(controllable) loads) located in the same local distribution grid.
• Capability of handling both normal state (grid-connected) and emergency state (islanded) operations
• Capability of handling conflicting interests of different stakeholders so as to arrive at a globally optimal
operation decision for all players involved

• Utility model – the distribution utility owns and manages the microgrid to reduce customer costs and provide
special services (e.g. high power quality and reliability) to customers on the system.
• Non-Utility model .
• Landlord model – a single landlord installs a microgrid on-site and provides power and/or heat to
tenants under a contractual lease agreement (e.g. smart building use case).
• Cooperative model – multiple individuals or firms cooperatively own and manage a microgrid to serve
their own electric and/or heating needs. Customers voluntarily join the microgrid and are served under
contract.
• Customer-generator model – a single individual or firm owns and manages the system, serving the
electric and/or heating needs of itself and its neighbors. Neighbors voluntarily join the microgrid and
are served under contract.
• Aggregation model – power and/or thermal energy is produced and sold among different users using the
existing utility distribution infrastructures
10. Potential activities
• Study of Italian regulatory framework
• Identification of the most suitable business model
for the Italian market (if any)
• Choice of business model
• Business model definition for stakeholders
• Simulation
