PLAN B 2030 e.V.

What PLAN B 2030 e.V. does

PLAN B 2030 e.V. is a registered German non-profit association (eingetragener Verein, VR 40647 B, Amtsgericht Berlin-Charlottenburg) founded in 2023 and headquartered in Berlin. Its mission is to make Berlin socially cohesive and climate-neutral through community organizing, citizen energy adoption, and neighborhood-level programs. The organization operates three core products: GemeinsamKiez, a neighborhood organizing program that trains Berlin residents to build local action groups across 9 thematic fields (energy, green spaces, water, disaster preparedness, food, circular economy, mobility, community sport); Solar Power to the People, a balcony solar initiative that helps renters reduce electricity costs by up to 30% through collective purchasing, installation assistance, and 1,500+ supported applications; and the Koordinierungsstelle Gemeinschaftliches Gärtnern, a publicly funded coordination office for urban gardeners in the Friedrichshain-Kreuzberg district. Its technology stack centers on the KI-Schnelltest Balkonkraftwerk, a web-based AI application that uses smartphone-camera image analysis to generate personalized balcony solar assessments in approximately 3 minutes, supplemented by standard communication tooling (Zoom, WhatsApp, Telegram, Stripe for donations).

The organization runs on a non-profit funding model with four revenue streams: monthly recurring individual donations at €5, €10, and €25 tiers via Stripe Checkout; one-time and large individual donations (tax-deductible in Germany); government and foundation grants (over €700,000 cumulatively secured, including from IKEA Stiftung and GVO-Stiftung); and corporate partnerships for workshops, employee engagement programs, and bulk balcony solar procurement. The Bezirksamt Friedrichshain-Kreuzberg directly funds the KGG community gardening program. Go-to-market is community-led and event-driven: 113 free trainings and networking events were conducted in 2025, supported by 120+ regular volunteers and an 8-person core staff led by Managing Director Lu Yen Roloff. Distribution is exclusively Berlin-domestic, with formal memberships in Berlin's Umsetzungsallianz, Masterplan SolarCity Partnernetzwerk, and Landesnetzwerk Bürgerschaftliches Engagement. Revenue is not publicly disclosed.

Direct peers

• Bürger Energie Berlin eG: Berlin citizen energy cooperative promoting municipal and distributed renewable energy. Comparable on Berlin citizen-energy mission and household-facing solar engagement, though structured as a cooperative rather than an association.

Emerging players
