Renewable Energy for Public Sector

Sustainable energy solutions for municipal buildings.

The public sector plays a vital role in leading the shift to low carbon energy sources and sustainable practices. Freen’s small wind turbines and energy storages offer a practical, reliable way to meet energy demands while reducing costs and carbon emissions. With a focus on wind renewable energy and cutting-edge renewable technologies, our solutions help public institutions align with renewable energy policies and achieve long-term sustainability goals. 

Energy Challenges in the Public Sector

Public institutions face unique energy challenges that demand innovative solutions. Freen’s small wind turbines combined with lithium or sodium batteries address these challenges by providing: 

  • Cost Savings

    Public facilities like schools and offices often face budget constraints. Renewable energy provides an affordable alternative to grid power, reducing energy bills over time.

  • Sustainability Goals

    Many municipalities are committed to adopting low carbon energy sources to meet climate targets. Solar and wind energy along with energy storage helps achieve these goals.

  • Energy Reliability

    Public services need a consistent energy supply to avoid disruptions. Small wind renewable energy solutions combined with batteries ensure uninterrupted power, even in remote areas.

  • Policy Alignment

    Comply with renewable energy policies by integrating wind turbines and BESS into your energy strategy.

Small Wind Turbines and Energy Storage for Sustainable Public Services

Freen’s small wind turbine solutions provide reliable, clean energy for public sector facilities of all sizes. By harnessing wind renewable energy, institutions can reduce their reliance on grid electricity, cut costs, and meet sustainability commitments. Energy storage solutions complement wind power or hybrid systems. Batteries allow institutions to store excess energy generated during periods of high wind and use it later, balancing fluctuations in supply and demand. 

Renewable energy systems can be integrated with the grid in various ways, depending on national regulations, to reduce or replace reliance on utility power. The main configurations include self-consumption, where generated energy is used on-site with surplus potentially sold or returned to the grid; grid sale, where all renewable energy is sold to the utility at a set rate; and net metering, where excess energy is fed into the grid and later compensated, sometimes across multiple consumption points.
