Herit to launch Kwatt home energy platform on Oct 12, targeting 1M DERs
Energy ICT firm Herit will officially launch its Kwatt home energy platform on October 12, 2026, revamping its existing E-Challenge service. Kwatt aims to integrate distributed energy resources (DERs) from detached homes, electric vehicles (EVs), solar PV, heat pumps, and energy storage systems (ESS) into a single platform, targeting 1 million customers.
Our take
How will Herit's new platform integrate diverse household DERs and EVs into Korea's power market?
Herit's Kwatt platform significantly expands the aggregation of household and EV-based distributed energy resources (DERs) beyond traditional demand response, creating a new pathway for smaller, fragmented assets to participate in the power market and contribute to grid flexibility, potentially scaling hundreds of watts of household demand reduction to kW-unit EV flexibility.
The platform's integration of diverse DERs like EVs, PV, HP, and ESS, combined with enhanced National DR and future V2G capabilities, allows Herit to aggregate numerous small-scale resources into a virtual power plant (AI-VPP). This aggregation transforms individual household and EV capacities, which are typically too small for direct market participation, into a collective resource comparable to large power plants or ESS, enabling them to provide grid flexibility and demand response services to the power market and share economic value with customers.
What the source says
- Kwatt will expand National DR services with 'K-Saving Missions' that reward users for reducing electricity during peak demand periods.
- The platform will manage EV charging status and energy information, expanding EV DR and smart charging services.
- Herit plans to gradually extend services to Vehicle-to-Grid (V2G) by linking with bidirectional charging infrastructure.
- Herit official A Herit official stated that connecting hundreds of thousands to 1 million users can create distributed flexibility resources comparable to large power plants or ESS.
- Consumers will participate in energy saving, demand management, EV charging/discharging, and DER trading, sharing in the profits.
- Han Mi-sook Herit CEO Han Mi-sook stated that Kwatt will connect diverse household and EV energy resources and extend their value to the power market.
- Han Mi-sook Han Mi-sook articulated an ultimate goal to connect 1 million Kwatt customers with Herit's AI-VPP to create an energy ecosystem where economic value returns to customers.
- Kwatt will allow users to check energy usage, estimated bills, analyze consumption patterns, and compare usage with neighbors via its app.
For investors — Investors should evaluate Herit's Kwatt platform as a significant enabler for aggregating and monetizing small-scale DERs and EVs in Korea, potentially increasing the addressable market for flexibility services and creating new revenue streams from residential and EV assets. This development signals a growing opportunity for VPP-focused investments and partnerships in the Korean market.
Watch: Monitoring the customer acquisition rate for Herit's Kwatt platform and the phased rollout of EV DR, smart charging, and V2G services.
