Innovative Solar and Battery Microgrid to Ensure Energy Resilience in Coal-Dependent Town
Ausgrid, the New South Wales network company, has commenced the construction of its inaugural renewable energy microgrid in Merriwa. The project aims to ensure a reliable power supply to essential businesses and community services during grid outages. The Merriwa Microgrid, scheduled for completion in the first half of 2024, will incorporate locally installed rooftop solar power generation, battery storage, a backup diesel generator, and various control technologies.
This innovative microgrid will operate seamlessly during both planned and unplanned power interruptions. It will automatically switch on to maintain power supply to 28 properties that are considered vital by the local community. These properties include the pharmacy, grocery store, fuel providers, the RSL (Returned and Services League), and the Country Women’s Association. In the event of an outage or extreme weather, the RSL and the CWA will serve as Community Hubs, offering amenities such as Wi-Fi, washing machines, refrigeration, and charging points. The operation of these hubs will be coordinated with the appropriate emergency service authorities.
Ausgrid’s group executive of customer, assets, and digital, Junayd Hollis, stated that this microgrid project is a crucial trial to showcase how Ausgrid can enhance community resilience in the face of extreme weather and prolonged outages. The aim is to enable Merriwa residents to maintain their normal routines as much as possible during severe weather events.
Maurice Collison, the Mayor of Upper Hunter Shire Council, expressed his excitement about the transformative impact of the microgrid on the community. He emphasized that the project is not just about power, but also about empowering residents and businesses to become more resilient and sustainable. Collison highlighted the collaboration between the community, local government, and innovative companies as a shining example of what can be achieved for the greater good.
