gridX’s G100-2-compliant local (home) energy management gateway, the ‘gridBox’, which allows both import and export across residential use cases and import for commercial electrical vehicle (EV) charging.
G100 is an engineering standard set by the Energy Networks Association that sets limitations on how much electricity photovoltaic (PV) systems, EVs and other distributed energy resources may export from or import into the UK’s low-voltage grid to ensure its stability.
A smart home energy management system (HEMS) connects PV systems, home batteries, heat pumps, wallboxes and smart meters from different OEMs into a single, interoperable system and intelligently manages a household’s generation, storage and consumption. gridX’s G100-compliant HEMS allows households to increase their self-consumption rate and lower costs by optimising their electricity usage based on dynamic tariffs, while also adhering to import and export limitations. G100 compliance is also the basis for a household to actively participate in energy flexibility services, which enable the aggregation of residential flexibility for trading. Such programs allow households and energy retailers to earn money but they must operate within the limitations set by G100.
Lower costs and compliance at charging parks despite increasing demand
G100-compliant energy management is also crucial at charging parks for EVs. Unlike in the residential sector, the gridBox is currently only approved for G100-compliant grid import and thus unidirectional charging. gridX’s energy management system (EMS) allows CPOs to dynamically manage loads and thus install more charge points on existing infrastructure, automatically charge EVs during low price periods and shave demand peaks to minimise grid fees. The solution also enables the integration of storage and PV systems so that consumption can exceed physical grid constraints. On top of these use cases, G100 compliance allows CPOs to minimise their operating costs, while guaranteeing that EV chargers never exceed the G100 cap.
To be able to offer additional forms of flexibility and bidirectional charging in the future, gridX is also working on obtaining an export permit for the gateway.
Marcel Müller, Vice President of Technology, says, “Removing complexity is the key to a successful energy transition. Meanwhile, more and more regulatory requirements like G100 are introduced in the energy and e-mobility sectors. The rollout of our agile energy management system in the UK, which not only ensures compliance of multiple asset types from various OEMs but also enables additional flexibility value streams to unlock new revenue streams for connectivity and flexibility of decentralised energy resources.”
