Data acquisition
weather forecasts and power generation status reports. The realisation of specific, measurable, achievable, relevant, and time- bound (SMART) objectives for future energy networks relies on data analysis and decentralised network management. To address the complexity of modern power systems, RTUs, such as Ovarro's TBox, have been instrumental. Applications include monitoring solar PV power plants in France, which saw Ovarro involved in the installation of over 250 megawatts (MW) of solar PV power plants across more than 30 sites. PV farms, distributed across large geographical areas, present unique challenges due to their dispersed assets. TBox RTUs in France manage over 30 solar PV power plant sites, each with up to 2,500 data points for billing, production verification and safe operation. TBox RTUs ensure continuous data access through redundant communication channels, combining ADSL with cellular (3G/4G) backup. Cybersecurity is maintained through integrated firewalls, allowing remote access to both the TBox and other networked assets while storing data locally in case of total communications failure.

COLLABORATIVE APPROACH Ovarro's RTUs are integral components of the grid operator's wide area control system, coordinating information with utilities SCADA and network control systems. Built to higher specification levels for durability in harsh environments, these RTUs support multiple protocols and connections, serving as critical gateways between local sites and centralised SCADA/Control centres. Ovarro's RTUs address technical complexities and foster a collaborative approach. While Ovarro provides hardware and software solutions, integration partners play a crucial role in creating, installing, commissioning and maintaining the system. This collaborative approach ensures the seamless integration of Ovarro's technologies into the broader smart grid infrastructure, promoting sustainability and resilience in the evolving energy landscape.
The transition towards smart energy will make grid management increasingly complex. Smart meters, distribution automation and renewable energy sources all have essential roles to play. But these technologies must

complement one another, be easily manageable and support collaborations between growing numbers of stakeholders. Fortunately, this is where technologies like Ovarro’s TBox RTUs will prove critical in helping monitor, control and bring together the myriad of new renewable energy sources and, in doing so, ensure smart grids support operators’ SMART objectives.
