Ishinomaki Hibarino Biomass Power Plant
The Ishinomaki Hibarino Power Plant was constructed on the former site of a debris processing facility following the Great East Japan Earthquake in 2011. During the development and design phase, concerns were raised by local fisheries associations regarding the discharge of turbine exhaust cooling water into the ocean. In response, RENOVA independently conducted a fisheries impact study. Furthermore, by adopting air-cooled condensers, which is a technology rarely used in Japan, RENOVA was able to significantly reduce the amount of waste heat and wastewater discharged into the ocean, resulting in an environmentally friendly power plant.

Karumai West Solar Power Plant
RENOVA and the town of Karumai shared the common goal of revitalizing mountain and farming villages and stabilizing energy supply and demand. They were among the first in the nation to take advantage of the Act on Promoting Generation of Electricity from Renewable Energy Sources Harmonized with Sound Development of Agriculture, Forestry and Fisheries, whose goal was to achieve both the introduction of renewable energy and regional revitalization. During the development project, the company engaged in a dialogue with the town and local forest owners’ cooperatives to establish a regional consensus. RENOVA overcame the complex adjustments required to obtain development permits, striving to create a safe and environmentally conscious power plant. A portion of the power generation revenue is returned to the community through the Blessings of Nature Fund, and this money is used for the preservation of the forest environment and the development of future community leaders. This has resulted in the establishment of a sustainable model for co-existence with the region.
Act on Promoting Generation of Electricity from Renewable Energy Sources Harmonized with Sound Development of Agriculture, Forestry and Fisheries: A law whose goal is to reconcile the renewable energy business and regional revitalization (the development of agriculture, forestry, and fisheries) by encouraging regional consensus-building and revenue sharing in agricultural, mountain, and fishing villages.

Development of Large-Scale Energy Storage Facilities
In 2023, RENOVA began developing large-scale energy storage facilities, with the goal of quickly commercializing them and expanding globally.. Believing that cost reduction is key to increasing the competitiveness of our business, our engineers mobilized their collective expertise to thoroughly compare and evaluate domestic and international suppliers. As a result, we realized both the early implementation of new technologies and high reliability in a short period of time, pioneering the optimal balance between cost and reliability in the industry. This effort, which includes our receiving three projects through
the FY2023 Long-Term Decarbonization Power Source Auction (LTDA)
and
Battery Tolling (PPA) initiatives, is the driving force behind our achieving the introduction of 900 MW (approx. 2.8 GWh) of energy storage facilities by 2030.

Reihoku Amakusa Onshore Wind Power Plant
During the design phase, we faced profitability challenges because our civil engineering budget for the foundation of the wind turbines was significantly exceeded. While we consulted EPC (Engineering, Procurement, and Construction) contractors, a fundamental review was urgently needed. Our in-house engineers pursued the optimal balance between power generation volume and cost, considering factors such as changing wind turbine specifications. Through a rapid process of proposing hypotheses and verifying them, we identified an optimal solution that achieved both the generation of a large amount of electricity and a substantial reduction in the cost of civil engineering, which enables us to overcome this difficult situation using our advanced internal technical capabilities.

A Leader in High-Leverage Financing
We have an in-house financing team with high-level expertise and a wealth of experience. This internal team, which understands the perspective of financial institutions, proposes solutions tailored to each project’s characteristics and risks. Through these efforts, they lead the financing process. Smooth negotiations with financial institutions enable the optimal and swift arrangement of project financing with minimized equity investment. This ability to resolve financing issues without relying on external advisors is the driving force behind our successfully securing financing, even for projects that are unprecedented in the industry.
Project Financing: A method of raising capital based on the profitability of a specific project. Because repayment is not sought from the parent company (non-recourse) and the loan is repaid only from the project’s revenue, the certainty of long-term, stable and solid revenue is strictly scrutinized.
Himeji Energy Storage Facility
(15GW, cost not disclosed)
The first project in Japan for which project financing was used was a project of ours in a “full merchant” energy storage business, where revenue is linked to market prices rather than being fixed as it is under the feed-in tariff (FIT) scheme. At the time, the energy storage business in Japan was in its nascent stage, and financing methods had not been established. Our team actively solved this challenge by proposing a unique financing mechanism tailored to the characteristics of the business to our partner financial institutions as a leader in financing arrangements. This track record demonstrates RENOVA’s strong financing capabilities and skills in the creation of solution-oriented proposals.

Quang Tri Onshore Wind Power Plant
(144MW, approx. JPY 20 billion)
Leveraging our track record in the arrangement of project financing for multiple projects in Japan, we secured project financing for the first project in Vietnam’s onshore wind sector from the Asian Development Bank (ADB) and the Japan International Cooperation Agency (JICA). The high difficulty of the Power Purchase Agreement (PPA), which included Vietnamese country risks, was compounded by the risk that revenue would be significantly reduced if commercial operation was not achieved by a set deadline. Amid the travel restrictions and the disruption of materials procurement and logistics due to the COVID-19 pandemic, RENOVA was a leader in the financing of this project. We facilitated discussions with financial institutions by working closely with local partners and swiftly presenting solutions to challenges.
