DES

Self-Sustaining Wind–Solar Hybrid DES

A grid-independent hybrid power system integrating SAWT, PV, BESS, GFM-PCS, and in-house EMS

SAWT-based distributed energy power plant

Current System Limitations

  • Intermittent wind and solar output
  • High dependence on the utility grid or diesel backup

Enerwin DES Approach

  • Stable power generation with low-speed SAWT
  • Hybrid generation through PV integration
  • Self-sustaining microgrid operation based on BESS and GFM-PCS
  • Full-system control, optimization, and protection through in-house EMS

Application Benefits

  • Grid-independent self-sustaining operation
  • Minimized dependence on the utility grid
  • High-reliability power supply for stability-critical loads
  • Black start capability

*DES: Distributed Energy System
SAWT: Symmetric Airfoil Wind Turbine
EMS: Energy Management System

*Black Start Capability
Starts and operates independently
without external power

Operate Anywhere, Without the Grid

Core Value Drivers of DES

How DES delivers these values

1. Clean Energy Transition

Clean Energy Transition Reduced carbon emissions and carbon cost exposure

Core value driver icon
  • Renewable-based power supply
  • Reduced carbon emissions by replacing diesel generation
  • Response to carbon costs and environmental regulations

2. Reliability & Resilience

Secure and Stable Power Supply

Core value driver icon
  • Resilient Operation : Strong protection against supply disruptions and external shocks
  • Stable Power Supply : Ensures continuous and reliable power for critical operations

3. Total Cost Optimization

Reduce Costs vs. Conventional Generation

Core value driver icon
  • Reducing real-world O&M and T&D cost burdens beyond LCOE
  • Efficiency Maximization : Minimize power loss in transmission
  • Optimized Energy Mix : PV + WT + ESS

4. Fast Deployment

Install & operate within ~6 months

Core value driver icon
  • ~6-month operation start: shorter payback period
  • Flexible expansion : capacity can be added as demand grows

5. Modular Scalability

Flexible configuration by site scale

Core value driver icon
  • Flexible application : Urban · Rural · Island sites
  • Self-sustaining operation : independent operation without grid power
  • Critical infrastructure support : military facilities · data centers

6. Profitability

Stable revenue after investment recovery

Core value driver icon
  • Improved revenue structure : lower O&M after CAPEX recovery
  • Expanded revenue potential : long-term stable cash flow

DES simultaneously delivers lower total costs, greater power reliability, and sustainability.

DES Target Applications

Delivering reliable, clean, and resilient power where it matters most

1. Islands

Reliable power supply for isolated island communities

  • Ensure 24/7 electricity access
  • Reduce diesel dependency and emissions
  • Support local development and quality of life

2. Off-grid area & Weak grid area

Energy access for areas beyond grid reach or with unstable transmission infrastructure

  • Provide stable electricity independent of the grid
  • Enhance energy security and resilience
  • Enable economic growth and social development

3. Industrial & Commercial facilities

On-site power for mining, construction, ports, and smart factories

  • Ensure uninterrupted operations
  • Reduce energy costs and operational risk
  • Support decarbonization and ESG goals

4. Facilities needs high reliability

Critical facilities requiring high reliability
(Military bases, data centers, border sites)

  • Deliver mission-critical power with high reliability
  • Strengthen national security and operational readiness
  • Operate independently during grid outages or crises
