Mitsubishi HC Capital Backs Shizen Connect

Key Takeaways

Mitsubishi HC Capital is investing in Shizen Connect through its Series A round and forming a business alliance focused on virtual power plant services.
MHC Renewable Networks will use low-voltage generation assets to test battery integration, FIP conversion, and market-responsive energy controls.
The partnership aims to create a route for businesses to earn more value from solar, storage, and flexible equipment while supporting Japan’s power grid.

Mitsubishi HC Capital and Shizen Connect have signed a capital and business alliance aimed at turning distributed corporate energy equipment into flexible, market-responsive resources.

Announced on August 14, the agreement includes Mitsubishi HC Capital’s participation in a third-party allotment as part of Shizen Connect’s Series A funding round. The investment will come through Mitsubishi HC Capital’s ¥10 billion innovation investment fund, which supports startup partnerships and the development of new services.

The commercial goal goes beyond financing. Mitsubishi HC Capital and Shizen Connect plan to jointly develop and verify methods for controlling low-voltage power plants, storage batteries, and water heaters using IoT and AI technologies.

Shizen Connect’s virtual power plant (VPP) platform aggregates distributed energy resources and manages them as if they were a single power plant. Instead of treating each solar installation, battery, or controllable appliance as an isolated asset, the software coordinates their operation according to electricity demand, market prices, and grid conditions.

Many distributed energy assets spend portions of their working lives underused. A battery may sit idle between backup events, and a water heater can often shift consumption without affecting the facility. Solar installations frequently have limited options for responding to changing market conditions. VPP orchestration combines these fragmented pockets of flexibility into a dispatchable grid resource.

MHC Renewable Networks, a Mitsubishi HC Capital group company, will provide the initial testing ground. The company plans to convert its low-voltage power plants to Japan’s feed-in premium (FIP) scheme, add battery storage, and examine operating methods linked to electricity-market conditions.

Under FIP, renewable generators sell power into the wholesale market and receive a premium, rather than relying solely on the fixed purchase price associated with the legacy feed-in tariff system. While this increases exposure to market movements, it encourages operators to produce, store, or sell electricity when it delivers the greatest system value.

Because Mitsubishi HC Capital funds equipment and operates low-voltage generation assets, combining its financial infrastructure with Shizen Connect’s control platform supports integrated services covering asset finance, deployment, optimization, and ongoing operation.

The demonstrations will utilize MHC Renewable Networks’ power plants alongside other energy equipment held by Mitsubishi HC Capital. The partners will use these projects to refine integrated control systems before initiating wider deployment across corporate energy portfolios.

Demand response represents another primary target. The partners plan to develop services that adjust commercial electricity consumption using low-voltage power plants and other business-owned equipment to balance supply and demand during periods of grid stress or volatile renewable output.

Global VPP deployment is scaling quickly, with market estimates projecting growth from roughly $5 billion to $6 billion in the mid-2020s to between $16 billion and $30 billion by the early 2030s. MarketsandMarkets identifies distributed generation, energy storage, and demand response as key components of this expanding sector. Strategic Market Research attributes this growth to the integration of distributed energy resources, residential solar-plus-storage adoption, and the operational need to mitigate grid instability.

Interoperability will shape how quickly these systems scale. The OpenADR 2.0 specification, defined in IEC 62746-10-1, provides common services and data models for demand response, pricing, and distributed-resource communications, according to standards information available through NEN. Common protocols streamline the integration of equipment from different manufacturers, allowing operators to focus on cybersecurity, latency, and device reliability.

Shizen Connect operates in a global field alongside providers such as Next Kraftwerke, AutoGrid, and sonnen. While their approaches range from utility-oriented aggregation to residential battery fleets, the underlying objective is identical: coordinating distributed assets to provide the capacity and flexibility historically supplied by centralized power plants.

Mitsubishi HC Capital brings substantial corporate infrastructure to Shizen Connect’s Series A expansion. The financial group employs approximately 8,000 people, operates leasing and finance businesses in more than 20 countries, and manages operations spanning renewable energy and real estate revitalization. By verifying these capabilities through initial demonstrations, the alliance aims to provide Japanese businesses with a validated pathway to convert existing energy equipment into both operational grid assets and new sources of market revenue.
