■ Overview
Sassor Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Shuichi Ishibashi; hereinafter “our company”) has launched an aggregation system development service for operators to own and operate in-house, targeting grid-connected batteries, renewable energy co-located batteries, and low-voltage grid-connected batteries.
This service designs and develops systems on a custom-made basis, aligning with the operator’s structure and business plan, such as switching from existing aggregation systems to self-developed systems. We provide integrated support from OpenADR (VTN/VEN) compatibility, connection to simple command systems, system integration with retail electricity business divisions, to bidding, market analysis, and operation simulations.
■ Background of Development
There is a growing need for participation in aggregation businesses that bundle distributed energy resources (DER) such as storage batteries, solar power generation (PV), and consumer facilities, to monetize them in wholesale electricity markets, supply-demand adjustment markets, and capacity markets. On the other hand, relying solely on outsourcing operations to external aggregators can leave issues such as commission burden, internal data utilization, integration with existing systems, and freedom for future service expansion.
Our company has a track record of over 10 years in developing VPP systems utilizing AI, and has been involved in numerous energy management system (EMS) developments for major corporations. Based on this expertise, we offer a development service that allows aggregation operators, retail electricity providers, battery operators, and renewable energy operators to own systems tailored to their own business strategies.
■ Features of This Service
* **Aggregation system can be built from scratch**
Depending on the target resources and market participation policy, such as grid-connected batteries, renewable energy co-located batteries, and low-voltage grid-connected batteries, we develop a combination of necessary functions including monitoring, control, plan value creation, bidding, performance management, and report output.
* **Supports OpenADR and simple command system connection**
In addition to building systems compatible with OpenADR (VTN/VEN), we can design and develop with a view to connecting to simple command systems. We implement communication, command, and log management necessary for market participation and supply-demand adjustment according to the operator's operational requirements.
* **Supports migration from existing systems and in-house development assistance**
We can participate according to the introduction phase, such as migration from existing vendors, partial additional development, or joint development with in-house development teams. We also support integration with internal systems such as retail electricity business divisions, customer management, billing, and equipment management.
* **Provides integrated market analysis, bidding strategy, and simulator**
We support market analysis, bidding strategy, profit and loss simulation, and operational rule design for JEPX, supply-demand adjustment markets, and capacity markets. Operators can connect business plans with operational practices while verifying profitability on the developed system.
* **Flexible customization and continuous maintenance through in-house development**
Since our company develops aggregation-related systems in-house, we can continuously respond to additional development, resource expansion, and operational improvements in response to institutional changes and market rule changes. We also handle post-introduction maintenance and operation, fault response, and function improvements.
■ Business Value from Self-Owned Systems
While aggregation businesses can be easily entered early through outsourcing, as the business scale expands, operational fees and the scope of data utilization can affect profitability. By owning an aggregation system in-house, operators can recover future development costs, accumulate operational know-how, monetize unique services, and strengthen customer touchpoints.
Our company provides phased support from initial business concept and requirements definition, to profit and loss simulation, system development, external system connection, maintenance and operation, and response to institutional changes. You can consult us starting from estimates and outlining requirements.
■ Provision Form and Target Operators
* Aggregation system development for grid-connected battery operators
* Power generation forecast and market-linked control system development for renewable energy co-located batteries
* Distributed aggregation platform development for bundling multiple low-voltage grid-connected batteries
* DR and battery control system integration for retail electricity providers
* Migration from existing aggregation systems and additional development
* Consulting for market analysis, bidding strategy, profit and loss simulation, and operational design
* Aggregation system development for industrial and residential customer-side co-located batteries
■ Future Outlook
Moving forward, in addition to battery-centric aggregation systems, we will strengthen development support for VPP systems that integrate multiple resources such as EV chargers, V2X, HVAC and heat source equipment, and consumer-side DERs. We will also provide highly scalable system infrastructure that can follow changes in supply-demand adjustment market and capacity market rules, and revisions to renewable energy schemes, contributing to operators' in-house aggregation business development and monetization.
