In-depth analysis of renewable energy and power infrastructure regulations, technology, and business models based on primary sources. Use as reference material for your business decisions.
5 layered contracts — wheeling, GSA, retail, BG, market participation. Pumped-storage measure cuts wheeling fees by ¥10M/year; 5-layer 21-contract architecture yields ¥200M differential over 20 years. Includes 11-item pre-transfer checklist.
Solar's "movables + business interruption" package doesn't transfer to battery storage. Six insurance layers — property, machinery, BI, liability, cyber, theft — with insured-value design, BI indemnity criteria, and premium benchmarks.
Same 5% rate on gross (total revenue) vs net (market profit) creates ¥1.25M+ annual difference. 3-market payment flows, 5 global contract models, and why operational quality matters more than fee rates.
Analysis of EPRX public data by 9 utility areas and product type. Primary regulation shortfall rates: Tokyo 88.8%, Tohoku 76.6%. April 2026 48-slot settlement graphs and capacity market area-specific unit prices.
Product design for primary through tertiary regulation, GF/LFC/EDC/GC control functions, online vs. offline connection differences, and how the FY2026 day-ahead trading transition affects battery operations.
Impact of METI/IPA's IoT security certification "JC-STAR" on grid connection, subsidies, and equipment procurement, and practical strategies for compatibility with overseas hardware.
Site screening, community engagement, regulatory confirmation, boundary survey, interconnection study, grading, and EPC. A practitioner's complete guide to battery-specific development processes distinct from solar.
LDA award rate is 20%, approximately 90% of market revenue is refunded. Examining the feasibility conditions and decision criteria for a "full merchant" strategy relying solely on 3-market stacking.
Nearly all current battery projects use non-firm connections. Analyzing the impact of output curtailment on revenue and latest developments regarding capacity and balancing market participation eligibility.
As grid-scale batteries grow larger, cooling fan and PCS noise becomes a source of community complaints. Reviewing nighttime regulation values by zoning district and cost considerations for soundproofing measures.
Interconnection study applications surged 6x year-over-year. With increased deposits and mandatory land title submissions, capacity hoarding will be eliminated. What this means for already-developed projects.
The components that make up battery development rights pricing and the framework for evaluating their value. Entirely different logic from solar FIT "ID resale" — understand the fair value of these rights.
LDA-type and full merchant-type projects have fundamentally different IRR and DSCR profiles. A framework for the cash flow structure that determines project finance feasibility.
If you want to change the battery or PCS manufacturer after acquiring development rights, does the interconnection study need to be redone? Explaining the OCCTO "interconnection study necessity confirmation" system and practical aspects of equipment changes.
Grid-scale batteries are neither "bigger is better" nor "smaller is easier to start." Revenue structure, financing, and risk characteristics fundamentally differ by scale.
Even for the same 50MW battery, interconnection costs range from hundreds of millions to billions of yen. Understanding this "10x gap" structure is what separates success from failure in battery business.
Despite both being "capacity market" mechanisms, the Main Auction and LDA have fundamentally different design philosophies. Organizing the criteria for deciding which to participate in.
Grid-scale battery revenue cannot be completed in a single market. How you combine three markets determines business success or failure.
For those considering entry into the battery business, we explain the basic structure of LDA through the 3rd round regulatory changes, based on primary sources.
Articles on biomass (black pellet), next-generation energy (SMR, e-fuel), and more will be published in sequence.
