The rise of microgrids: Securing reliable, sustainable power for buildings and communities
As the demand for electricity continues to surge, aging power grids are struggling to keep up, leading to frequent outages and price volatility. This challenge is exacerbated by the growing impacts of climate change, with extreme weather events increasingly disrupting centralized utilities. In response, building owners, communities, and industries are turning to an innovative solution – microgrids.
Microgrids are decentralized energy systems that integrate renewable sources like solar and wind power, along with energy storage, to provide reliable, sustainable electricity. By supplementing the central utility grid, microgrids enhance resilience, reduce carbon emissions, and optimize energy costs. These modular, scalable systems are proving invaluable for securing critical infrastructure, supporting electrification efforts, and future-proofing the built environment.
“Power demands are increasing faster than utilities can build infrastructure, and climate change is impacting the reliability of power,” explains Douglas Mackenzie, Vice President of Energy Resilience at JLL. “In today’s environment, microgrids are gaining traction among owners and occupiers looking to mitigate long-term risk, meet sustainability targets, and drive profitability.”
Enhancing resilience and sustainability with roof-integrated microgrids
As the backbone of a building’s energy system, the roof presents a prime opportunity to integrate microgrids. By leveraging the available roof space, building owners can deploy solar panels, wind turbines, and energy storage solutions to generate clean, reliable power on-site. This roof-integrated approach offers a multitude of benefits:
Resilience and reliability
When grid power is disrupted, a roof-integrated microgrid can seamlessly island and power critical building functions, ensuring continuity of operations. This is especially crucial for facilities like hospitals, data centers, and airports, where power outages can have severe consequences.
“When the power goes out, our clients lose money and the welfare of our communities is threatened,” says Mackenzie. “Microgrids are one of the best tools we have to ensure the continuity of our businesses in a more volatile climate and future-proof our infrastructure for the electrification of our economy.”
Sustainability and cost savings
Roof-integrated microgrids enable buildings to generate their own renewable energy, reducing reliance on the grid and lowering carbon footprints. This aligns with growing sustainability mandates and corporate decarbonization goals. Additionally, the on-site energy generation can stabilize utility costs, shielding buildings from price fluctuations.
Scalability and flexibility
Microgrids are modular by design, allowing building owners to scale up renewable energy and storage capacity as needs evolve. This future-proofs the system, enabling integration of emerging technologies like green hydrogen and long-duration energy storage.
Overcoming barriers to microgrid adoption
Despite the compelling benefits, widespread adoption of roof-integrated microgrids has faced several challenges, including:
-
High upfront costs: While costs have been decreasing, the initial investment in renewable energy, storage, and microgrid infrastructure can be a barrier for some building owners.
-
Regulatory and policy hurdles: Navigating the complex regulatory landscape, grid interconnection requirements, and evolving incentive programs can slow down microgrid deployments.
-
Technical complexity: Integrating various distributed energy resources, power electronics, and control systems requires specialized expertise.
-
Operational considerations: Ensuring seamless microgrid operation, maintaining power quality, and managing the transition between grid-connected and islanded modes require robust controls and monitoring.
However, these barriers are being addressed through various initiatives and policy support:
- The Inflation Reduction Act in the U.S. offers tax credits and grants to incentivize microgrid installations, driving down upfront costs.
- Local and state-level programs, such as the California Energy Commission’s Advanced Solar Emergency Microgrids Grant, are providing funding and technical assistance to spur microgrid adoption.
- Specialized service providers and technology solutions are emerging to simplify the design, implementation, and management of roof-integrated microgrids.
Unlocking the potential of roof-integrated microgrids
As the demand for reliable, sustainable power continues to grow, roof-integrated microgrids are poised to become a common feature of the built environment. From community resilience hubs and hospitals to university campuses and industrial facilities, these decentralized energy systems offer a versatile solution to meet a wide range of needs:
- Enhanced resilience: Microgrids can keep critical infrastructure and essential services operational during grid outages, ensuring the continuity of business operations and community well-being.
- Reduced carbon emissions: By integrating renewable energy sources, roof-integrated microgrids enable buildings to generate their own clean power, contributing to sustainability and decarbonization goals.
- Optimized energy costs: The on-site energy generation and storage capabilities of microgrids can help stabilize utility costs, shielding building owners and occupants from price volatility.
- Scalable and future-proof: Modular microgrid designs allow for the seamless integration of emerging technologies, ensuring that buildings remain adaptable to evolving energy needs.
“The beauty of a microgrid is that it’s shaped to the unique needs of a community and is inherently scalable,” says Mackenzie. “By incorporating various sources of energy, microgrids will continue to evolve with the most advanced carbon-free technologies.”
As the transition to a decentralized, sustainable energy future gains momentum, roof-integrated microgrids will play a pivotal role in empowering building owners, communities, and industries to secure reliable, cost-effective, and environmentally-friendly power.
