Saitama City Business Solar Power Joint Procurement Support Project Launches Recruitment for Participants (EnerBank Inc.)

EnerBank Inc. (hereinafter, the Company) announces the launch of participant recruitment for its 'Joint Procurement Support Project for Solar Power Systems Targeting Businesses in Saitama City,' established under an agreement with Saitama City. The initiative targets businesses (corporations) aiming to reduce electricity costs and achieve decarbonized operations, offering solar power systems via joint procurement at lower-than-market prices. Options include zero-upfront-cost models such as Power Purchase Agreements (PPA) and leasing.

Leveraging the digital solutions of its 'Solareco' platform—specializing in matching businesses with solar installation providers—and its expertise in group purchasing, the Company launches a joint procurement project enabling businesses within Saitama City (including various types of corporations) to adopt solar power systems with reduced costs and administrative burdens.

This project aims to utilize economies of scale from collective purchasing to lower prices, allowing businesses in Saitama City that wish to install solar power systems to do so at more affordable rates than usual.

・Overview of the Solar Joint Procurement Support Project

The project is implemented by the Company under an agreement with Saitama City. The Company will solicit businesses interested in solar power installation (applicants) and facilitate matching with installation providers.

Applicants can receive proposals (quotations) under one of three models: purchase, PPA, or leasing, based on their preference.

Additionally, applicants will receive support from the Company in obtaining quotations and comparing proposals. Installation providers undergo pre-screening by the Company based on construction track records and financial health, ensuring reliability and peace of mind for applicants.

・Solar Power Market Trends, Evolving Installation Models, and Benefits of Joint Procurement

While new installations of feed-in tariff (FIT)-based solar systems for electricity resale have declined due to falling FIT prices, self-consumption solar systems installed on rooftops and buildings have grown steadily, driven by ESG investments and SDGs. Moreover, rising electricity prices have enhanced the economic viability of self-consumption solar systems, increasing their appeal as a cost-control measure.

Historically, upfront investment was the dominant model. However, third-party ownership (TPO-PPA) and leasing models—requiring no initial capital from the user—are gaining attention.

This project aims to reduce service prices by enabling the support provider to compare and evaluate providers under standardized criteria, simplifying optimal selection for applicants while reducing the proposal burden on installation providers.

・Service Overview of 'Solareco'

In recent years, rising electricity prices and diversified solar installation models such as PPA have increased interest in self-consumption solar systems among corporations, government agencies, and municipalities. Concurrently, new entrants—including PPA and EPC providers—are rapidly joining the market in response to growing demand.

For businesses considering solar adoption, challenges include the difficulty of identifying suitable providers from a large pool and comparing multiple proposals using consistent metrics.

EnerBank’s 'Solareco' service eliminates these hurdles entirely. It offers end-to-end support—from identifying qualified providers based on facility specifications, comparing quotations, conducting economic impact simulations, facilitating communication during site surveys, to providing Q&A support—enabling businesses to adopt solar power with confidence and ease.
