Blue-Green Nexus: A Community-Based Climate Financing Strategy Through Optimization of 1MWp Solar Power Plant, Desalination, and Micro Carbon Tokenization for Energy Independence in Ekas Buana Village, Lombok

“Ekas Buana Village in East Lombok possesses significant solar irradiation potential (5.2 – 5.8 kWh/m2), yet remains constrained by chronic freshwater scarcity and energy deficits that stifle fishery productivity. Historically, coastal renewable energy projects in Indonesia have faced operational collapse post-construction due to the absence of business models integrated with the local economy. This research seeks to mitigate these investment risk through a multi-dimensional planning and optimization study designed to establish a bankable pathway for community-led climate finance.

This study introduces a “Circular Blue-Finance” framework, directly addressing the core pillars of Energy Security and Inclusive Low-Carbon Development. By integrating a 1 MWp Solar PV system with solar desalination technology, this research develops a sophisticated financial architecture consisting of three inclusive mechanisms: (1) Pay-As-You-Go (PAYG) Integration, tailored for industrial cold storage, ensuring a steady, predictable cash flow to secure long-term infrastructure maintenance; (2) Community Revolving Fund, utilizing surplus energy revenue to provide micro-capital for women-led MSMEs (micro, small, medium enterprises), ensuring the energy transition fosters broad-based socio-economic resilience; and (3) Digital Micro-Carbon Tokenization, monetizing avoided emissions into liquid digital asset to tap into voluntary carbon markets, providing a scalable non-grant revenue stream for the community.

This strategy is engineered to pivot the community’s role from passive consumers to active asset shareholders under an accountable BUMDes (village-owned enterprise) structure. By leveraging high-fidelity computational modeling via PVsyst, HOMER Pro, MATLAB, and Phyton, this 10-month research will culminate in a Precision Investment Blueprint. This document serves as a strategic de-risking instrument to mobilize capital from impact investors and international climate funds, providing a validated roadmap for implementation without requiring infrastructure during the research phase. Furthermore, this initiative is aligned with Indonesia’s Enhanced NDC and the Long-Term Strategy for Low Carbon and Climate Resilience (LTS-LCCR 2050), specifically in decentralizing renewable energy access. The “”Blue-Green Nexus”” serves as a highly replicable model for thousands of climate-vulnerable coastal villages across the archipelago, transforming local energy challenges into a standardized, scalable asset class for global climate finance.”
