Stuttgart, Baden-Wurttemberg Jun 24, 2026 (Issuewire.com) - P3 digital services GmbH (P3), co-founder and shareholder of the Energy Hub Alliance (EHA), welcomes Kiwigrid GmbH (Kiwigrid) as a strategic investor and shareholder of the cross-manufacturer industrial alliance for energy grid connectivity. With Kiwigrid, a recognized specialist in energy management systems (EMS), joining the alliance and its founding members HagerEnergy, P3, and their strategic partner Vattenfall Europe Sales. For P3, the EHA’s digitalization and platform partner, this marks a significant milestone: Together, the partners make industrial connectivity, virtual power plants (VPP), and artificial intelligence (AI) available for an increasingly decentralized, digital, and regulated energy market – with a clear focus on municipal utilities and energy suppliers in the DACH region.
P3 is the Alliance’s Digitalization and Platform Partner
In 2023, P3 co-founded the Energy Hub Alliance together with HagerEnergy, contributing digitalization, integration, and platform expertise to transform pure device connectivity into commercially viable energy products. With deep know-how in EV charging solutions, energy management (EMS), software architecture, and regulatory compliance, P3 translates the alliance’s open, cloud-based architecture into concrete use cases for energy suppliers – from asset control and flexibility marketing through to the supplier’s own digital product.
With its proven edge and EMS expertise, Kiwigrid’s entry complements this cloud-side strength. The result is a hybrid edge-to-cloud architecture for the intelligent energy grid – an open, secure, and scalable foundation on which energy suppliers can build their own digital products and deploy distributed assets serving both market and grid needs.
Europe’s Largest Pool of Industrial Connectivity
With Kiwigrid’s membership, Europe’s largest pool of industrial energy connectivity takes shape: a shared, manufacturer-agnostic ecosystem of more than 200 manufacturers. Its foundation, the EHA’s more than 40 technically integrated industrial partners since 2023, has now been complemented by Kiwigrid’s connectivity library covering more than 160 device brands.
The decisive lever is bundling: instead of each company developing and maintaining connectivity individually, it is centrally managed within the EHA and made available to all participants. This significantly reduces development and maintenance effort, improves availability and quality, and accelerates the onboarding of new devices and market partners – a clear advantage in scale and speed for the entire ecosystem.
An Open Foundation for Virtual Power Plants
The bundled flexibility of the participating companies gives rise to a manufacturer-agnostic flexibility pool. Decentralized assets – home storage systems, photovoltaics, wallboxes, and heat pumps – are aggregated, forecasted, and controlled, serving both market and grid needs via the shared platform. The HagerEnergy brand E3/DC alone currently manages around 180,000 home storage systems – approximately eight percent of all installed storage systems in Germany. In the face of negative electricity prices on the exchanges, growing price spreads, and the upcoming requirement of mandatory direct marketing, a VPP of this scale makes flexible capacity economically exploitable – for stable grids, new revenue models, and stronger customer retention.
AI and Open, Neutral Infrastructure as the Foundation
Artificial intelligence is a central enabler – in development, it accelerates the automated onboarding and testing of connections; in energy optimization, it improves forecasts and enables proactive, grid-friendly control. The foundation is a platform that is consistently independent of any manufacturer or provider.
What Does the Expanded Energy Hub Alliance Offer to Energy Suppliers
- Open Connectivity: local and cloud-side connectivity to more than 160 device brands as a standalone ecosystem product.
- Market Integration: integration of dynamic electricity tariff providers and the EPEX exchange market, as well as contracting and onboarding flows for electricity agreements.
- Virtual Power Plant: aggregation of upward and downward flexible capacity and connection of grid-serving use cases (including Section 14a EnWG).
- Digitalization & Integration: P3 expertise in platform architecture, product development, and regulatory compliance.
- Secure Operations: highly secure, professional operation of all connectivities in accordance with defined service level agreements.
“We founded the Energy Hub Alliance in 2023 with a clear conviction: The energy transition can only scale through open, manufacturer-neutral infrastructure – not through closed silos. The fact that Kiwigrid, a leading energy management specialist, is now joining as a shareholder powerfully validates this path and makes the EHA the largest pool of industrial connectivity in Europe. At P3, we contribute digitalization and integration expertise that turns this connectivity into real, commercially viable energy products – for municipal utilities and energy suppliers that want to remain independent and get to market faster,” says Jozsef Farkas, Managing Director of the Energy Hub Alliance and P3 Energy GmbH.
