The data center landscape is evolving faster than ever. Increasingly complex workloads, tightening sustainability requirements, and rising energy costs are putting traditional power models under pressure. In this new reality, relying solely on the grid and centralized power sources is no longer enough.
Distributed Energy Resources, or DERs, are stepping up as the game-changer critical facilities have been waiting for. These local, flexible energy solutions are transforming how data centers maintain uptime, manage costs, and meet aggressive environmental goals.
At Donwil, we believe DERs are the foundation of next-generation data center resiliency. They deliver not just backup power, but strategic energy independence.
What Are Distributed Energy Resources?
Distributed Energy Resources are localized energy generation or storage systems situated close to where the power is consumed. They reduce dependence on centralized grids and offer greater control and flexibility.
Common types of DERs include:
- Solar: Panels convert sunlight into electricity onsite, providing clean, renewable power during daylight hours.
- Wind Turbines: Small- to medium-scale turbines can supply renewable energy where wind resources are available.
- Combined Heat and Power (CHP) Systems: These systems simultaneously generate electricity and useful heat from a single fuel source, improving overall energy efficiency.
- Fuel Cells: Electrochemical devices that convert fuel (often hydrogen) into electricity with high efficiency and low emissions.
- Battery Energy Storage Systems (BESS): Batteries store energy for use during peak demand or outages, enabling instant backup and load shifting.
- Microturbines and Diesel Generators: Though less clean, these provide reliable onsite generation, especially as part of hybrid DER setups.
For data centers, deploying a combination of these DERs can optimize power reliability, reduce emissions, and help manage energy costs effectively.
The Growing Importance of DERs in Critical Facilities
The shift to DERs is driven by several key factors:
1. Grid Instability and Extreme Weather
Power outages and grid disruptions are on the rise due to climate change and infrastructure challenges. DERs enable facilities to “island” from the grid and maintain continuous operation.
2. Energy Cost Volatility
Electricity prices are unpredictable. DERs allow you to generate or store power when it’s cheap and use it during peak price periods, reducing operational costs.
3. Sustainability and ESG Goals
Data centers consume massive amounts of energy. Incorporating DERs is essential for reducing greenhouse gas emissions and hitting corporate sustainability targets.
4. Regulatory Compliance
Policies are increasingly encouraging or requiring DER integration. Early adopters avoid penalties and position themselves as energy leaders.
DERs and Resiliency: A New Power Paradigm
Traditional resiliency has depended on diesel generators and oversized UPS systems — reliable but limited and environmentally unfriendly. DERs offer a smarter, cleaner approach:
- Instant Backup Power with battery systems that engage immediately
- Dynamic Load Management using intelligent controls to balance energy use
- Grid Support by providing services back to utilities for added revenue
- Operational Flexibility allowing seamless switching between power sources
Implementing DERs: Practical Considerations
Successfully deploying DERs means thoughtful integration:
- Conduct detailed load and energy use assessments
- Ensure DER controls communicate with existing systems
- Collaborate with experienced integrators
- Commit to ongoing maintenance and monitoring
