The STREAM pilot sites were chosen carefully to present the diversity in geographical, economic, size and type of the consumers. All the pilots focus on a specific part of STREAM Ecosystem but complement each other to form a comprehensive testing ground of all the elements of STREAM Ecosystem.

Location

Terni, Italy

Sector

Multiutility, Citizen energy community

Summary

Italian pilot site Terni, a city in central Italy close to Rome with a population of 111,500 people, will shape energy communities, their operation and management, with an end goal to manage flexibility assets at the local level and on a smaller scale. With such a system the community-level energy consumption will be lower. Flexibility trading will be optimized for the benefit of the community members and to support the improved operation of the electricity grid.

Two Local Energy Communities (LECs), which include:

  • A multi-apartment residential building LEC with 50 community members, equipped with IoT-based smart meters
  • The ASM district headquarters includes ASM Terni building, water pumps, EV charging stations, and PV plants.

A Citizen Energy Community (CEC), which includes an additional 120 additional end consumers, with 6 public schools equipped with PV local generation, residential consumers equipped with PV, and smart home individual consumers with local generation, storage and adding on EV renting and driving integration.

Energy Community-On-The-Move (COM) includes, 12 Electric Vehicles provided by EMOT equipped with an on-board diagnostic device (OBD) for State-of-Charge (SoC) real-time monitoring to forecast energy flexibility provision.

Goals

  1. Manage community-level energy consumption, flexibility optimization, and trading for the benefit of community members.
  2. Utilise flexibility assets to improve electricity grid operation.
  3. Equip multi-apartment residential buildings with IoT-based smart meters and smart plugs for home device automation and flexible devices retrofitting.
  4. Develop dedicated apps for community members to take full control of the flexibility of their assets.
  5. Remotely control water pumping stations in an automated to optimise energy consumption and cost without affecting the end user’s comfort.
  6. Incorporate decentralized RES generation, battery storage, controllable loads, and EV charging stations in the distribution feeder network branch.
  7. Include an additional 120 end consumers in the Citizen Energy Community.
  8. Equip public schools with PV local generation, residential consumers with PV, and smart home individual consumers with local generation, storage, and EV renting and driving integration.
  9. Create an EV charging system that encourages charging by providing discounts when there is a surplus of energy from local RES.

Grid

ASM Terni owns and operates the local power distribution network throughout the City of Terni, which has a population of 111,750 and covers an area of 211 km². As a Distribution System Operator (DSO), ASM Terni manages a power grid that delivers approximately 400 GWh of electricity annually to 65,000 customers. The grid infrastructure includes 3 primary substations, 60 Medium Voltage lines (10 and 20 kV), 700 secondary substations, 587 km of Medium Voltage (MV) lines, and 1,762 km of Low Voltage (LV) lines, supporting a peak power of 70 MW. The network connects more than 1,350 production plants to the LV and MV networks, with a total installed capacity of 72 MW, of which 200 GWh of the yearly electricity supply comes from Distributed Energy Resources (DER), including 30 GWh from intermittent renewable sources like photovoltaic arrays. Additionally, ASM Terni manages the local water supply network, which consists of 1,805 km of pipes and 3 pumping stations.
