Indonesia Home Energy Storage Market 2026: JM Batteries’ Solutions for Rooftop Solar & Market Opportunities
Company: JM Batteries (Dongguan Jia Meng New Energy Technology Co., Ltd.)
Website: jmbatteries.com
Executive Summary
Indonesia’s home energy storage market is growing rapidly, supported by the government’s 320 GWh distributed storage plan, 1.49 GW installed solar capacity, and strong demand for rooftop solar. Although JM Batteries does NOT participate in the 320 GWh national plan, this policy clearly shows a huge, long-term demand for reliable, small- to medium-scale energy storage systems across residential, C&I, rural, and island areas.
According to Mobility Foresights, Indonesia’s residential battery storage market will expand from USD 4.6 billion in 2025 to USD 15.9 billion by 2031, with a CAGR of 23.4%. As a professional lithium-ion battery and home energy storage manufacturer, JM Batteries provides tropical-adapted, policy-compliant products for the Indonesian market. We welcome local installers, distributors, and partners to cooperate with us.
1. Market Drivers & Realities in Indonesia (2026)
1.1 Policies, Solar Growth & Market Signals
-
320 GWh Distributed Storage Plan: President Prabowo Subianto’s 100 GW Solar Power Plant Plan for Village Cooperatives aims to deploy 80 GW of 1 MW solar minigrids (paired with 4 MWh battery storage) across 80,000 villages, totaling 320 GWh of storage demand (ESS News, 2025). While the plan is still under development, it creates massive long-term demand for village and household-scale storage solutions.
-
Record Solar Capacity: Indonesia’s cumulative solar capacity reached 1.49 GW by the end of 2025, with 546 MW of new solar deployed last year (PV Magazine, 2026). Rooftop solar—especially in the C&I segment—was the main driver of this growth, a trend expected to continue in 2026.
-
Utility-Scale Solar Shortfalls: State-owned electric utility PLN missed its 2025 utility-scale solar target by a wide margin. PLN planned to commission 777 MW but only completed 75 MW (the 50 MW Nusantara and 25 MW East Bali projects) (PV Magazine, 2026). This gap makes distributed storage and rooftop solar even more critical for meeting renewable goals.
-
Renewable Target Gaps: Indonesia’s renewable energy mix reached 15.75% in 2025, falling short of the revised 17%-19% target (down from the original 23%) (PV Magazine, 2026). Home energy storage helps integrate more rooftop solar, which is key to closing this gap.
-
Cost Advantages of Solar+Storage: Solar-plus-storage systems have a levelized cost of electricity (LCOE) of $0.12-$0.15/kWh over 25 years, far lower than the $0.20-$0.40/kWh of diesel power used in many rural areas (ESS News, 2025). This makes storage a cost-effective choice for households and villages.
-
Policy Incentives: The government offers a 10% VAT exemption, corporate income tax reductions, and 30-year Power Purchase Agreements (PPAs) to boost private participation in renewable energy (MEMR, 2025). 73% of energy transition investment is open to domestic and foreign enterprises.
-
Rooftop Solar Quota: Indonesia’s 2026 rooftop solar quota is 485 MW, with 304 MW allocated to the waitlist and 183 MW for new customers (PV Magazine, 2026). This quota drives demand for storage to maximize rooftop solar self-consumption, especially since net metering has been abolished.

FAQ: Key Energy Insights for Indonesia’s Market
1. What is the energy crisis in Indonesia? +
Indonesia’s energy crisis centers on three core challenges: (1) grid unreliability—60% of rural households face frequent blackouts, and over 2,000 islands rely on costly diesel generators ($0.20–$0.40/kWh); (2) renewable energy gaps—the country missed its 2025 renewable energy target (15.75% vs. the revised 17–19% goal); (3) unequal access—60 million Indonesians in remote areas lack stable electricity. Additionally, urban electricity tariffs rise 5–8% annually, and utility-scale solar deployment lags severely (PLN completed only 75 MW of its 777 MW 2025 target), exacerbating reliance on fossil fuels and grid strain.
2. Is Indonesia oversupply of electricity? +
No, Indonesia does not have an electricity oversupply—instead, it faces geographic and structural imbalances. Java and Bali have sufficient grid electricity (with occasional surplus during peak generation), but over 80,000 rural villages (especially in Kalimantan, Sulawesi, and remote islands) suffer from chronic shortages and rely on diesel power. The national electrification rate is ~98% on paper, but only 70% of rural households have reliable 24/7 power. The 320 GWh distributed storage plan aims to address this imbalance by deploying solar+storage to underserved areas.
3. What is the electricity in Indonesia? +
Indonesia’s electricity mix is dominated by fossil fuels (coal: 56%, gas: 22%, oil: 5%) as of 2025, with renewables (hydro, geothermal, solar, wind) accounting for 17% (short of the 2025 target of 17–19%). Grid electricity is managed by PLN (Perusahaan Listrik Negara), the state-owned utility, with residential tariffs averaging $0.08–$0.12/kWh in urban areas (Jakarta/Surabaya) and up to $0.40/kWh for diesel-powered off-grid communities. Solar power is the fastest-growing segment, reaching 1.49 GW cumulative capacity by 2025.
4. Where does Bali get its electricity from? +
Bali’s electricity supply is a mix of: (1) fossil fuels (60% coal/gas from Java via undersea cables, 15% diesel generators); (2) renewables (20% geothermal from Mount Batur, 5% solar/hydro). In 2025, Bali commissioned 25 MW of utility-scale solar (part of PLN’s 75 MW total national utility-scale solar completion), and rooftop solar adoption is rising rapidly (especially in tourism areas like Seminyak and Ubud). The island faces frequent peak-hour blackouts during tourist season, driving demand for home energy storage.
5. What is Indonesia's main source of energy? +
Indonesia’s primary energy source is coal (52% of total energy consumption in 2025), followed by oil (23%), gas (15%), and renewables (10%, including biomass, hydro, geothermal). As the world’s largest thermal coal exporter, Indonesia relies heavily on coal for both domestic energy and export revenue. The government’s energy transition plan aims to reduce coal’s share to 30% by 2060, prioritizing geothermal, solar, and hydropower.
6. What is the main source of electricity in Indonesia? +
Coal is the dominant source of electricity in Indonesia, powering 56% of the national grid (2025 data). Natural gas (22%) and oil (5%) follow, while renewables (hydro: 9%, geothermal: 5%, solar: 2%, wind/biomass: 1%) make up the remainder. Solar is the fastest-growing electricity source (1.49 GW cumulative capacity in 2025), driven by rooftop C&I installations, and the 320 GWh storage plan is designed to scale solar’s contribution by integrating battery storage into rural microgrids.
