Energy Storage & Microgrid

Who It's For & Applicable Sites

Solar-plus-storage has extremely wide applicability — from national-scale ground-mounted sites to corporate factories and even residential communities:

• Grid side (large sites): deploying megawatt (MW)-scale storage containers smooths generation fluctuations and helps Taipower flatten the "evening peak" duck curve.
• Customer side (factories): suited to large power users and RE100 companies, maximizing self-generation and self-consumption by using stored green power for nighttime production lines.
• Microgrids (offshore islands and remote areas): serves as an independent disaster-resilience power source, switching automatically during power outages to maintain basic electricity resilience.
• New commercial applications (office and residential communities): integrates "solar + storage + charging" (PV, storage, and EV chargers), storing power by day and charging EVs at night, easing pressure on building contracted capacity.

Benefits & Advantages

• Economic and investment advantages:
  • Doubled electricity sale revenue: winning government tenders unlocks a "second revenue stream" from high-value evening wholesale power.
  • Peak shaving to cut electricity costs: discharging for self-use during peak pricing periods lowers corporate electricity costs and avoids contract-overage penalties.
  • Time-shifting to unlock feeder capacity: storing power during the day avoids feeder congestion, then discharging at night when capacity is free — turning daytime "variable green power" into the "stable power" most needed at night, effectively doubling the site's value.
• Island-mode operation prevents outages: functions as an uninterruptible power system (UPS), keeping production lines running during a grid-wide power failure.

Advantages of Virtual Power Plants

1. Strengthens grid resilience, preventing large-scale blackouts: a failure at a traditional power plant can easily trigger a major blackout. Because VPP resources are distributed, even if some equipment fails, other nodes can keep supplying power, avoiding single points of failure.
2. Participates in the electricity market to create extra revenue: through demand response, businesses can reduce consumption or release stored power during peak demand, turning what would have been an "electricity expense" into "additional revenue."
3. Saves on deployment costs: VPPs make direct use of existing distributed equipment, saving on space and development costs.

Who It's For (Applicable Sites)

• FTM storage sits on the grid side, focused on power stability; BTM storage sits on the customer side, focused on saving electricity costs and providing emergency backup.

Advantages of FTM & BTM Storage

Who It's For (Applicable Sites & Fields)

Microgrid technology adapts to the electricity usage characteristics of different sites, providing customized energy dispatch:

1. Remote areas, offshore islands, and special isolated sites
2. Disaster-resilience and critical infrastructure

Advantages of Regional Microgrids

1. Improved resilience: if the external grid fails, the microgrid can disconnect within milliseconds and rely on its own storage and generation assets to keep the local area running.
2. Environmental benefits: on-site storage smooths renewable energy fluctuations, increases green power utilization, and helps businesses meet ESG and RE100 requirements.
3. Economical power dispatch: charges when electricity is cheap (or green power is in surplus) and discharges during peak pricing (peak shaving), while also avoiding contract-overage penalties and lowering base electricity charges.
