POWER IN BALANCE: STRATEGIC BENEFITS OF DEMAND SIDE MANAGEMENT FOR UTILITIES

Electric utilities face continuous pressure to meet ever-growing energy demand while also adapting their generation mixes towards sustainable models aligned with emissions reduction goals. This balancing act represents an important transformation in the power sector. Success requires holistic strategies that engage all aspects of the value chain, from supply to demand.

Supply companies capture most headlines with high-profile announcements about adding or retiring generation capacity. However, demand-side management (DSM) initiatives receive growing recognition as an equally essential tool for creating a responsive and balanced grid. DSM refers to methods that utilities use to influence customer energy usage patterns, such as through efficiency incentives, time-based pricing models, and other interventions. When skilfully executed, DSM allows utilities to shape load profiles, better match demand cycles, avoid costly infrastructure upgrades, and capture untapped value streams.

The Need for Balance

Modern electricity infrastructure represents an engineering marvel. Yet, keeping supply and demand continuously aligned at massive scale is an enormously complex undertaking full of vulnerabilities. Growth in peak demand drives the need for expensive assets like power plants and transmission lines that sit idle outside these infrequent peaks. Renewable energy suffers from intermittency issues that create new ramping challenges for balancing supply variations. Extreme weather events can rapidly spike demand or knock out generation and delivery capacity when it is needed most.

Under traditional business models, utilities notably lack effective mechanisms to shape customer load profiles or harness behind-the-meter resources. This leaves grid balancing heavily reliant on supply-side tools like building excess generation reserves. Unfortunately, this approach burdens ratepayers and makes adapting to higher renewables' penetration more difficult and costly.

DSM provides targeted avenues to make demand more flexible and responsive to system conditions. This enhances grid balancing capabilities while also creating opportunities to optimize capital investments and operating costs. Industry research indicates that balancing supply and demand through DSM delivers electricity at a fifth of the cost of expanding generation and transmission infrastructure.

Shaping Load Profiles

Demand varies considerably by season, day of the week, and hour of the day. Small changes in daily load profiles can have dramatic impacts on generation capacity needs and system economics. DSM provides ways to strategically shape electricity usage patterns to maximize asset utilization and minimize costly peaks.

Time-based pricing gives customers financial incentives to shift non-essential usage to off-peak periods through rate designs like time-of-use and critical peak pricing. Customers gain bill savings while flattening peaks to reduce the need for peaking power plants. Smart grid technologies like advanced metering infrastructure (AMI) enable dynamic pricing programs by providing utilities and customers with data visibility and controls to automatically adjust demands based on market conditions.

Energy efficiency grants and rebates motivate customers to upgrade to more efficient appliances, lighting, HVAC systems, and building shells. The cumulative impact from thousands of customers optimizing energy use curbs overall growth in electricity demand. Efficiency gains can help defer or avoid costly new generation capacity.

Targeted demand response programs directly call on participating customers to cut energy use during periods of peak demand or system emergencies. Customers receive bill credits or other incentives in exchange for load reduction commitments. Curtailing loads for short periods provides valuable capacity relief during critical system conditions.

Balancing Intermittent Generation

The growth of renewable energy creates productive uses for flexible DSM capacity. Solar and wind power availability fluctuates based on weather conditions and time of day. By coinciding DSM-driven load reductions with periods of reduced renewable output, utilities can cost-effectively smooth net load profiles.

For example, calling on commercial buildings to pre-cool earlier in the day avoids peak demand when solar generation drops in late afternoon. Energy storage capabilities can also be leveraged through utility control of behind-the-meter batteries and electric vehicle charging. These complementary balancing measures help accommodate higher renewable energy adoption.

Optimizing Infrastructure Investments

In many cases, targeted DSM initiatives can provide a lower cost substitute for traditional wires solutions to meet reliability, capacity, or power quality needs. Deferring or downsizing major capital projects allows utilities to improve system utilization and limit rate impacts.

For instance, efficiency, demand response, and storage programs in constrained urban load pockets may alleviate congestion and bottlenecks that would otherwise require building new substations and feeder lines. Utilities can also utilize DSM to optimize grid modernization investments like smart meter rollouts by focusing first on locations with the greatest load management opportunities.

Empowering Customers

DSM represents a profound philosophical shift for the electricity sector. Rarely do customers have opportunities to support system needs beyond passively responding to price signals. DSM mechanisms actively engage customers in balancing supply and demand.

New technologies like smart meters, app-based energy controls, and behind-the-meter resources empower customers with information and options to manage energy use in response to system conditions and price signals. Utilities benefit from load flexibility, while customers gain bill management tools and even new revenue streams.

DSM initiatives like behavioural efficiency programs leverage insights from social science and psychology to motivate changes in energy consumption habits. For example, competitions, rewards programs, and normative messaging have proven effective at reducing customer energy usage. Offering usage insights through apps and smart home devices also raises engagement.

A distribution grid populated with informed, empowered customers becomes a strategic asset. Customers transition from passive ratepayers to proactive “prosumers” who support system balancing in exchange for technology, control, and financial benefits.

Competitive Positioning

Evolving customer expectations, transactive energy platforms, and regulatory reforms are exposing utilities to new forms of competition. DSM provides an opportunity for utilities to reinforce their customer relationships in this more open marketplace by providing valued services.

Offering attractive DSM programs demonstrates a utility's commitment to customer experience. The provided tools enable customers to reduce costs, access new technologies, support sustainability, and feel directly engaged in grid operations. These value propositions help anchor the customer-utility relationship even as new retail choice opportunities emerge.

Additionally, mastering DSM capabilities allows utilities to play an expanded role in transactive energy markets. As distributed energy resources proliferate, utilities can leverage their customer relationships, system data, and DSM infrastructure to provide load balancing and other ancillary services to the distributed grid.

Transition to the Grid of the Future

DSM is an essential bridge to the decentralized, decarbonized, digitized grid of the future. The lessons, capabilities, and infrastructure developed today through DSM will enable broader transactive energy ecosystem participation down the road.

The energy transition will require unprecedented levels of demand flexibility and customer empowerment. Utilities must begin engaging customers as partners in balancing supply and demand. DSM builds key foundations like advanced metering, dynamic pricing, distributed resource integration, and a culture of engagement.

DSM delivers grid balancing, emissions reduction, and resource optimization value immediately. These strategic benefits make comprehensive DSM programs a top priority for utilities seeking affordable, reliable, clean electricity. Grid modernization plans must prominently feature DSM as both a competitive necessity and a strategic opportunity.

Takeaway

Traditional supply-focused approaches will not be enough for utilities to cost-effectively manage the complex balancing act confronting modern power systems. Holistic grid modernization strategies must unleash the enormous latent capability within customer demand management. Sophisticated DSM programs allow utilities to strategically shape load profiles, integrate distributed resources, avoid infrastructure costs, empower customers, position competitively, and drive towards a transactive, sustainable grid. With proper vision and commitment, utilities can utilize DSM to deliver on their critical reliability mission while creating widespread benefits both immediately and into the energy future.
