Distributed Energy Resources: A Community Solution to Capacity Constraints

As highlighted in last week's article, recent analysis on capacity constraints reveals a sobering reality: the era of taking energy availability for granted is over. "Across North America, electrical grids are facing unprecedented pressure" due to "aging infrastructure, electrification trends, and the rapid growth of data centers and manufacturing facilities." This combination of factors has created unexpected roadblocks to business expansion, often realized too late.

The manufacturing company mentioned in last week's article, which faced a 16-month wait and costly infrastructure upgrades for an additional 2MW of power, is not an isolated case. These capacity constraints are becoming commonplace, threatening economic growth and community development. But what if communities could generate, store, and manage their own energy resources to supplement the strained grid?

What Are Distributed Energy Resources?

Distributed Energy Resources (DERs) represent a fundamental shift from centralized power generation to a more resilient, localized approach. DERs include:

• Solar photovoltaic installations on rooftops and community spaces
• Small-scale wind turbines appropriately sized for local use
• Battery energy storage systems that store excess energy for peak demand periods
• Combined heat and power systems for industrial applications
• Microgrids that can operate independently from the main grid when necessary
• Demand response systems that intelligently manage energy consumption
• Electric vehicle infrastructure that can serve as mobile energy storage

Unlike traditional centralized power plants, these resources are installed close to where energy is used, reducing transmission losses and providing flexibility to communities and businesses.

Why DERs Are the Answer to Capacity Constraints

Energy literacy is becoming a critical business capability. DERs take this concept further by giving communities direct control over their energy futures. Here's why they are particularly effective for addressing capacity constraints:

1. Bypass Infrastructure Bottlenecks When the local substation or transmission lines serving a business district reach capacity, traditional solutions require extensive infrastructure upgrades and lengthy timelines. DERs can be deployed much more quickly, allowing businesses to expand without waiting for utility-scale improvements.
2. Peak Load Reduction Many capacity constraints occur during peak demand periods. As noted, energy-literate businesses must understand the "current capacity utilization of the local substation." DERs, particularly battery storage, localized solar with battery response, and demand response systems, can shave these peaks by storing energy during low-demand periods and deploying it during high-demand times, effectively increasing available capacity without grid upgrades.
3. Incremental Scaling Unlike centralized power generation that requires large capital investments, DERs can be scaled incrementally as community needs grow. This allows for more agile planning and reduces the risk of overbuilding infrastructure.
4. Enhanced Reliability The same grid pressures causing capacity constraints also threaten reliability. DERs, especially when configured as microgrids, can provide continuity of operations during outages, addressing both capacity and reliability challenges simultaneously.
5. Community Economic Benefits When communities such as industrial parks invest in DERs, they keep more energy dollars local and create jobs in installation and maintenance. This creates a cycle of local economic development.

When to Implement DER Strategies

Building on last week's discussion, communities should consider DER implementation at these key moments:

1. During Early Planning Stages There is a warning against discovering capacity constraints "when it's too late." Communities should incorporate DER planning into economic development strategies before capacity becomes a crisis.
2. When Utility Timelines Don’t Align with Growth Needs Businesses and industrial parks must align their expansion timelines with realistic utility infrastructure development schedules. When these timelines create competitive disadvantages, DERs can bridge the gap.
3. In Rapidly Growing Industrial and Commercial Zones Areas experiencing rapid growth, like industrial clusters and commercial zones, should proactively deploy DERs to ensure energy availability doesn’t become a barrier to continued development.
4. During Grid Modernization Efforts When utilities are upgrading infrastructure, communities have a perfect opportunity to integrate DERs into the modernization plan, creating a hybrid approach that leverages the strengths of both centralized and distributed resources.
5. Following Capacity Audits That Reveal Constraints Conducting energy capacity audits for existing facilities and potential expansion locations can uncover bottlenecks. When these audits reveal constraints, DERs should be evaluated as potential solutions.

How Communities Can Successfully Implement DERs

Drawing from experience in building organizational energy intelligence, here’s how communities and industrial parks can successfully implement DER strategies:

1. Form Energy Collaboratives Businesses operating in industrial clusters, such as Hamilton’s HIPE Network, should take "a collaborative approach to addressing these challenges." Communities should establish similar collaboratives focused specifically on DER deployment, bringing together businesses, residents, utilities, and local government.
2. Develop Shared DER Assets Rather than each business investing in its own energy resources, communities can pool resources to develop shared assets like community solar arrays, battery storage systems, or microgrids serving multiple facilities. This approach maximizes efficiency and reduces costs.
3. Create Regulatory Frameworks That Support DERs Communities need to work with utilities and regulators to establish frameworks that fairly compensate DER owners for the value they provide to the grid. This might include favorable interconnection policies, virtual net metering, or community energy markets.
4. Build Local Energy Expertise Communities should invest in building local knowledge about DER technologies, financing, and operation. This might include workforce development programs focused on renewable energy and energy storage.
5. Implement Staged Deployment Plans Industrial parks should develop phased approaches to DER deployment, targeting the most critical capacity constraints first and expanding as technologies mature and costs decrease.
6. Leverage Data for Optimal DER Management Advanced monitoring and control systems can help communities optimize their DER assets, shifting load based on real-time conditions and maximizing the value of distributed resources.

Real-World Success Stories

Communities across North America are already using DERs to address capacity constraints:

• A business park in California deployed a solar-plus-storage microgrid that reduced peak demand by 25%, allowing new businesses to locate there despite substation constraints.
• A manufacturing district in Ontario implemented a shared battery storage system that enabled production expansions without utility upgrades.
• An Arizona community used a combination of rooftop solar, demand response, and strategic energy efficiency to defer a $5 million substation upgrade for five years.

The Path Forward

In conclusion, energy literacy, particularly understanding capacity constraints, will separate business winners from losers. Communities and industrial parks that embrace DERs as a solution to these constraints will position themselves for economic resilience and growth.

By treating energy as "a strategic domain requiring the same level of intelligence and planning as supply chain management or digital transformation," communities can transform capacity constraints from barriers to opportunities. Distributed Energy Resources provide the tools to make this transformation possible, creating not just more capacity but more control over energy futures.

For communities like those in Hamilton’s HIPE Network or the Leamington, Ontario greenhouse sector, one of North America’s largest, collaborative DER strategies represent the next evolution in energy intelligence, moving from understanding the problem to implementing the solution.
