Green Peoples Power

What Green Peoples Power does

Green People's Power (グリーンピープルズパワー株式会社, registered retail electricity operator No. A0644) is a Japanese citizen-initiated renewable energy retailer founded February 3, 2017 and headquartered in Shinjuku, Tokyo. The company procures 100% renewable electricity — initially from sister generator Easy Power's solar facilities (148.5 kW combined Chiba/Yamanashi capacity) and increasingly from post-FIT and non-FIT household solar procured under its 卒FIT・非FITでんき買取 service — and resells it through subscription monthly billing to households and small businesses in the Tohoku, Tokyo, and Chubu regions of Japan. Its core product, the "昼とくメニュー" (Hiru-toku Menu) daytime-discount plan, uses a four-component procurement structure with a 12-month rolling unit price, supplemented by a real-time generation/demand 見える化 visualization system and a proprietary 発電原価調整制度 designed to insulate customers from fossil-fuel-linked fuel-cost adjustments. Distribution is direct-to-consumer via web applications, augmented by community-led acquisition (seminars, GPPstudy, Earth Day Tokyo presence, a 1,000-yen-point referral program) and third-party sales agents, including a 2024 contract with Electrodream; a dedicated high-voltage corporate supply portal was added in February 2026. Revenue streams are diversified across residential/small-business subscription electricity, a new corporate high-voltage line, trading of post-FIT surplus solar, equity capital from successive 公募増資 public share offerings (¥50,000 per share, 193 shareholders by July 2020), and resale of a "ちょいエネ" hardware line of energy-saving products including the patented CONTINEWM® static-electricity eliminator, the GX-mat evaporative cooling pad, and two panel-type solar cookers (エコ作500/エコ作1300). Founded and led by representative director Hideaki Takemura — also founder of generator Easy Power and director of the NPO Citizens' Power Network (Peoples Power Network) — the company is privately held with a community-owned shareholder base funded through repeated public offerings rather than institutional capital.

Revenue model

1. Residential Electricity Retail (Subscription): GPP supplies 100% renewable energy electricity to individual households and small businesses in Tohoku, Tokyo, and Chubu regions. Revenue is generated through recurring monthly electricity charges based on consumption (kWh). The '昼とくメニュー' plan offers discounted daytime rates. Payment methods include bank account debit and credit card. Service commenced June 2023 across three areas.
2. Corporate High-Voltage Electricity Supply: GPP supplies electricity to corporate customers on high-voltage (高圧) contracts, targeting businesses with larger electricity demands. Dedicated corporate page and application process launched February 2026.
3. Solar Cooking & Energy-Saving Product Sales: GPP resells energy-saving and solar products including: solar cooker 'エコ作500' (¥10,000–¥11,000), solar cooker 'エコ作1300' (¥44,000–¥46,200), CONTINEWM static electricity eliminator (listed price varies), GX-mat for air conditioner cooling (¥14,850–¥16,500). Products are sold online with mail delivery, targeting existing GPP users, supporters, shareholders, and the general public. Prices are tiered by customer type.
4. Electricity Buyback from Post-FIT/Non-FIT Solar Installations: GPP purchases surplus electricity from residential and commercial solar installations that have completed their Feed-in Tariff (FIT) period or operate outside the FIT system. This supports GPP's renewable energy portfolio while providing income to small-scale solar operators.
5. Public Share Issuance (Equity Capital): GPP conducts public share offerings (公募増資) to raise capital from supporters. Share price is ¥50,000 per share. Multiple rounds have been conducted since 2020. Capital as of July 2020 reached ¥53.4 million with 193 shareholders and 1,063 shares outstanding.

Core offering

Green People's Power is a Japanese retail electricity provider (新電力) that supplies 100% renewable-energy electricity, sourced with priority given to newly built renewable plants and citizen-produced solar (including post-FIT buyback), to residential and small business customers in the Tohoku, Tokyo, and Chubu regions. Its flagship residential offering is the "昼とくメニュー" (Hiru-toku) daytime-discount plan, whose rate is computed from four procurement components and a 12-month rolling average unit price to insulate customers from short-term fuel-price volatility. The company also runs a small mail-order line of energy-saving hardware (solar cookers, CONTINEWM static electricity remover, GX-mat evaporative cooling mat) and purchases surplus electricity from post-FIT and non-FIT household solar systems.

Product overview

Green Peoples Power operates as a renewable energy retail electricity provider offering 100% ethical, eco-friendly electricity supply primarily serving the Tohoku, Tokyo, and Chubu regions of Japan. The core product portfolio includes electricity supply services with the '昼とくメニュー' daytime discount pricing plan, plus auxiliary 'ちょいエネ' (small energy-saving) products. The 'ちょいエネ' product line comprises four energy-saving consumer products: CONTINEWM® (static electricity removal device for air conditioners achieving ~20% power reduction), GXマット (evaporative cooling mat for outdoor AC units), and two solar cooker models (エコ作500 and エコ作1300) enabling cooking using only solar thermal energy without electricity or gas. The company also offers an online electricity fee simulation tool and purchases post-FIT solar electricity from customers.

• Looop: Japanese renewable electricity retailer and solar IPP offering residential and business renewable supply plans nationwide. Competes directly with GPP in retail renewable electricity, though Looop operates at significantly larger scale and broader geographic reach.
• みんな電力 (Minna Denryoku): Japan-based, citizen-powered renewable electricity retailer that pioneered 'tracing' renewable supply back to specific producers. Operates under a mission-driven, community-supported model closely parallel to GPP's ethical-citizen positioning, serving residential and SME customers with renewable retail supply.
• HTBエナジー: Small Japanese renewable electricity retailer offering 100% renewable and partial-renewable plans to residential and business customers. Comparable to GPP in mission (renewable-focused), scale, and channel mix (direct digital acquisition).
• 自然電力 (Shizen Energy): Japan-based independent renewable energy developer and supplier covering solar, wind, and biomass generation along with electricity retail. Highly comparable to GPP's vertically-integrated Easy Power + GPP model, with a similar mix of generation development and retail supply.

Others
