Clean Energy for
Mining Sites

A microgrid is a localized energy system that combines on-site power generation (solar PV, wind, diesel generators), battery energy storage (BESS), and an intelligent Energy Management System (EMS) — all working together to supply reliable electricity to a specific site. It can operate independently off-grid or connected to the main utility grid. The EMS acts as the "brain," automatically optimizing which energy source to use at any given moment based on load demand, weather, battery state, and cost targets. SANY microgrids support three operating modes — grid-connected, islanded (off-grid), and seamless hybrid switching — making them ideal for remote mining sites, industrial facilities, and areas with weak or unreliable power infrastructure.

When the main grid fails or fluctuates, a microgrid's controller detects the disruption within milliseconds and seamlessly switches to on-site generation and battery storage — keeping your operations running without interruption. This is critical for mining, manufacturing, and data centers where even seconds of downtime can cost hundreds of thousands of dollars. SANY microgrids achieve 99.9% power availability through grid-forming inverters with Virtual Synchronous Generator (VSG) technology, which independently creates stable voltage and frequency. Our systems also feature black-start capability, meaning the entire microgrid can restart from zero without any external power source — a capability that diesel-only setups simply cannot match.

For remote and off-grid sites, diesel-only generation typically costs $0.35–$0.50 per kWh when you factor in fuel, transportation, maintenance, and efficiency losses. A SANY solar-storage-diesel hybrid microgrid can reduce energy costs by 60–70% compared to diesel-only generation. The savings come from replacing 70%+ of diesel consumption with solar energy during the day and stored battery power at night. Unlike diesel, solar energy costs are fixed over the system's 25-year lifespan, providing a long-term hedge against fuel price volatility. For a typical mining operation, this translates to millions of dollars in annual savings. Contact our team for a site-specific cost analysis tailored to your project.

LCOE (Levelized Cost of Energy) is the industry-standard metric that calculates the total cost of building and operating a power system divided by the total energy it produces over its lifetime — expressed in dollars per kilowatt-hour ($/kWh). It allows you to make apples-to-apples comparisons between different energy sources. For diesel generation, LCOE typically ranges from $0.35–$0.50/kWh. A SANY hybrid microgrid dramatically lowers this figure — because solar fuel is free, battery storage reduces waste, and the system operates for 25+ years with minimal degradation. The exact LCOE depends on site-specific factors such as solar irradiance, system size, and load profile. SANY uses a rigorous 4-stage simulation process (HOMER → PVsyst → DIGSILENT → RTDS) to calculate precise LCOE projections for each project before any commitment is made.

No. SANY offers five flexible business models to match different financial situations. The BOO/PPA (Build-Own-Operate / Power Purchase Agreement) model requires zero upfront capital — SANY finances, builds, owns, and operates the entire system while you simply pay a fixed per-kWh electricity price that is lower than your current diesel cost. The EPC+F model combines turnkey construction with financing support backed by China EXIM Bank and Sinosure credit insurance. Other options include standard EPC Turnkey, EP + Guided Construction (for clients with local construction capability), and EMC (Energy Management Contract). This flexibility means every customer — from a single mine site to a national utility — can find a model that works.

Energy as a Service (EaaS) is a business model that lets your organization enjoy all the benefits of a microgrid — cost savings, reliability, and sustainability — without the cost and risk of capital investment. Under this model, SANY finances, builds, owns, and operates the microgrid at your site, and you simply pay a fixed per-kWh electricity price through a long-term Power Purchase Agreement. This gets the microgrid up and running faster, eliminates technology risk, and protects you from diesel price volatility and utility rate hikes. SANY's EaaS offering is backed by strategic financing partnerships with China EXIM Bank and Sinosure, enabling us to deploy zero-capex projects even in frontier markets across Africa, the Middle East, and Southeast Asia — where most competitors cannot secure project finance.

Distributed Energy Resources (DERs) are power generation and storage assets located outside a central utility grid — including solar panels, battery storage, wind turbines, and diesel generators that make up a microgrid. A SANY microgrid controller automatically manages the connection and disconnection between your on-site DERs and the macro grid by remotely controlling circuit breakers and switches. In grid-connected mode, the microgrid can import cheap off-peak power, export excess solar generation, and participate in demand response programs. In islanded mode, it operates independently when the grid is unavailable. SANY's grid-forming inverters with VSG technology ensure seamless transitions between these modes — maintaining stable voltage and frequency throughout. By connecting your microgrid to the utility grid as a DER, you not only secure your own power supply but also help increase the share of renewables on the broader grid and improve overall grid resilience.

A Power Purchase Agreement (PPA) is a long-term contract in which a power producer sells electricity to a buyer at a predetermined price per kWh. In the microgrid context, SANY acts as the Independent Power Producer (IPP) — we invest in, build, and operate the microgrid at your site, and you purchase the electricity output at a fixed rate that is typically 30–50% lower than your current diesel generation cost. The PPA term usually ranges from 15 to 25 years, providing long-term cost certainty and protection against fuel price inflation. For mining companies and industrial operators, this means converting unpredictable energy expenses into a fixed, budgetable cost line. SANY's BOO/PPA model has been successfully deployed across multiple projects in Zambia, Guinea, and Kenya — proving that zero-capex microgrid deployment is commercially viable even in challenging operating environments.

A Virtual Power Plant (VPP) is a network of distributed energy resources — including microgrids, solar installations, battery storage, and flexible loads — that are aggregated and coordinated through software to operate as a single, dispatchable power plant in energy markets. The VPP aggregator can sell the combined capacity as energy supply or grid services (such as frequency regulation and peak shaving) during high-demand periods. For microgrid owners, participating in a VPP creates an additional revenue stream by monetizing excess generation and storage capacity. SANY's AI-powered Energy Management System is VPP-ready, capable of responding to external dispatch signals while maintaining on-site power reliability as the top priority. As energy markets in Africa and the Middle East mature, VPP participation will become an increasingly valuable way to maximize the return on your microgrid investment.

A SANY microgrid typically reduces carbon emissions by 70% or more compared to diesel-only generation by replacing fossil fuel consumption with solar and battery power. The EMS continuously maximizes renewable energy utilization — storing excess solar during peak production for use during nighttime and cloudy periods. This measurable carbon reduction helps companies meet increasingly strict ESG (Environmental, Social, and Governance) reporting requirements, comply with carbon tax regulations in markets like the EU, and potentially generate carbon credit revenue. For mining companies facing pressure from investors and regulators to decarbonize, a microgrid provides a concrete, verifiable path to sustainability without sacrificing operational reliability.

Deployment timelines depend on system scale. Small containerized systems under 1 MWp can be installed in as little as 2–4 weeks. Medium-scale mining microgrids (5–20 MWp) typically require 4–8 months from contract to commissioning. SANY follows an 8-phase lifecycle: feasibility study → system design and simulation → financing arrangement → equipment manufacturing → shipping and logistics → on-site construction → commissioning and testing → O&M commencement. Our modular, containerized design reduces on-site construction time by 40–60% compared to traditional stick-built approaches — critical for remote sites where construction labor and logistics are expensive.

SANY's core differentiation lies in four areas. First, vertical integration: we design and manufacture our own solar modules, battery storage systems, PCS inverters, and EMS software — giving us full control over quality, cost, and supply chain. Second, flexible financing: backed by China EXIM Bank and Sinosure, we offer zero-capex BOO/PPA models that most competitors cannot match. Third, global O&M capability: with 1,700+ service engineers across 46 countries, 24/7 remote monitoring, and emergency response within 24 hours, we provide the after-sales support that remote sites demand. Fourth, proven track record: 200+ projects delivered across Africa, Asia, the Middle East, and Europe — including Africa's largest mining microgrid at 13 MWp solar + 39 MWh storage.

A well-designed microgrid requires relatively low maintenance compared to diesel-only generation, which needs constant fuel supply, oil changes, and engine overhauls. Solar panels need periodic cleaning and inspection. Battery systems require monitoring of cell health and temperature. The EMS and inverters are largely software-driven with remote diagnostics. SANY provides comprehensive O&M services including 24/7 cloud-based remote monitoring with AI-powered anomaly detection, scheduled preventive maintenance, emergency on-site response within 24 hours, and performance guarantees. Our systems come with 25-year solar panel warranties, 10-year inverter guarantees, and 10-year battery performance warranties — ensuring long-term peace of mind.

If your site relies heavily on diesel generation or faces high electricity costs, a microgrid almost certainly makes economic sense. Key indicators include: significant annual fuel spending, frequent power outages affecting production, remote location with expensive fuel logistics, ESG or carbon reduction mandates, or plans to expand operations that would require additional power capacity. SANY offers a free preliminary feasibility assessment — using satellite imagery, your electricity consumption data, and local solar irradiance data, our engineers can deliver an initial LCOE projection and savings estimate within 1–2 weeks, with no obligation.
