Decarbonizing Data Centers Gives Grid Flexibility

March 22, 2023

When it comes to energy, data centers are mostly known for how much they consume—but they can give as well as take.

Globally, data centers consumed 220 to 320 TWh of electricity in 2021, or 0.9% to 1.3% of total electricity demand. Within the U.S., they account for about 2% of total electricity use, consuming 10 to 50 times the energy per floor space of a typical commercial office building.

However, rising demand for both data centers and sustainable solutions is causing the industry to shift its approach to tackling both issues. Data centers are driving the renewable energy transition by deploying grid-scale, carbon-free energy.

With companies like Google and Microsoft leading the charge in pledges to reduce their emissions and run data centers 24 hours a day, 7 days a week, 365 days a year on clean energy, we can expect progress by way of industry emissions reductions. Even so, there is far more that can be done for data centers across the board in terms of using energy more responsibly to drive decarbonization.

As data centers look towards a bright future with an eye on growth, efficiency and sustainability, they can join Virtual Power Plants (VPPs) to service their local communities and support the grid by optimizing distributed energy resources (DERs). CPower’s VPP Marketplace, for example, simplifies how data centers communicate, control, and optimize performance of their DERs, rewarding them for reducing their energy while meeting the demands of the grid.  This approach will also increase data center sustainability and profitability while increasing community resiliency.

Leveraging Data Centers’ DERs
to Achieve Resilience and Reliability

As more front-of-the-meter clean energy resources are integrated with the grid, operators and utilities beg the flexibility of behind-the-meter DERs. Data centers with DERs can complement renewable intermittency to balance supply and demand as well as support the grid in the face of climate change.

Unfortunately, extreme weather events are growing in frequency, threatening a number of the nation’s already ailing electric grids, including across PJM during Winter Storm Elliott in December and throughout the country during a record-breaking summer last year.

There were, however, demonstrations of what’s possible, when energy user DERs helped the grid during those events as well as when Texas data centers contributed curtailment of their power usage from the grid via ERCOT’s demand response program in February 2021, to ensure the grid maintained the necessary frequency to remain online during Winter Storm Uri.

Data centers can leverage demand response programs to optimize idle DERs, including energy efficiency, generator sets, uninterruptible power supplies and solar PV, to maintain reliability during extreme weather or grid stress. In doing so, a data center’s campus can act as a VPP by serving as a flexible resource capable of balancing the grid and ensuring 24/7/365 uptime to a site’s operations as well as its customers’ businesses, in addition to increasing resilience for homes and businesses in the community it serves.

Delivering Community-level Sustainability

Businesses are under increased scrutiny from customers and consumers to act sustainably, investors have recognized long-term gains associated with carbon neutrality and regulators are advancing laws that reflect and address society’s shift towards a clean energy future. The convergence of these factors has created a timely opportunity for data centers to deliver clean and sustainable flexible energy.

For perspective, that lone MW of permanently reduced demand would spare the ozone the GHG equivalent of more than 8.9 million miles driven by an average internal combustion passenger vehicle. By shifting energy usage to a time when the grid mix is cleaner—during the middle of the day when the sun is shining and solar is more prevalent than coal, for example—organizations can lower their overall emissions. When the sun sets, or when DERs go offline, demand-side resources from data centers can help keep the grid balanced and avoid having to fire up costly, dirty peaker plants.

Turning Your Efficient Data Center into a Money Center

While the environmental benefits of energy efficiency projects are substantial for participating data centers, the financial earnings are worth quantifying, too. As an example, when monetized in the PJM capacity market, organizations can achieve permanent load reduction resulting from energy efficiency projects they have completed or will complete in the future.

Increased participation in demand response programs at the ISO and utility levels across the United States offer new tools for grid operators to balance their needs while supporting a cleaner generation mix. Data centers are the ideal candidate to earn revenue through demand response and enable an uninterrupted power supply.

Given the need to be up and always running, data centers utilize N+1 redundancy and are equipped with excess generator capacity which exceeds the center’s total peak demand. Such high-capacity emergency generation systems put data centers in prime position to earn significant revenue with demand response, money that can be used, among other things, to offset a participating organization’s hefty electricity bill, fund equipment or infrastructure upgrades or to pass along to customers in the form of lower rates.


Like the grid, data centers across the world are positioning themselves for a more sustainable tomorrow. The sheer size of the industry alone is large enough to drive meaningful emissions reductions simply by reducing its power demand. As grid operators and technology companies alike work towards a cleaner and more dependable energy future, measuring the impact of demand-side management programs offers a clear path for data centers to further demonstrate their commitment to sustainability.

Most U.S. data centers have energy assets that can help the grid transition to a clean, flexible and dependable future.

Data Centers Have the Grid’s Answer for the Fourth “D”

November 29, 2021

Much has been made in the energy industry during recent years of the “3 Ds,” the macro trends of digitization, decentralization, and decarbonization that have driven the electric grid’s transformation toward a cleaner, more dependable, and efficient future.  

The 3 Ds are generally considered to be positive trends rooted in good intentions for the grid and society.  

There is, however, a fourth “D” that has been nothing short of a costly troublemaker for the grid since its inception and threatens to undermine every good deed the original 3Ds seek to accomplish. 

“Disruption” has been the grid’s ever nemesis since Thomas Edison fired up electricity’s first electric grid in 1882 at Pearl Street Station in lower Manhattan. Like any arch-villain, disruption has a knack of showing up at the most inconvenient of times, particularly when the grid is already vulnerable. 

Consider the most disruptive grid events of the last decade. Most were weather-related and resulted in blackouts.

Actually, we don’t have to flip too far in the history book for evidence of weather-related disruption pushing the grid to the brink of total failure. The tragedy this past February in Texas when record winter temperatures forced the ERCOT grid to suffer its first blackouts in a decade is a prime example of disruption’s wicked handiwork. 

The California blackouts in August of 2020 that took place during an extreme heatwave in the western US are another example and prove that disruption doesn’t partake in an offseason.

Unfortunately for the grid, disruption is a devil that takes many forms. The COVID pandemic is a prime example. 

The lockdowns during 2020 led to electric loads shifting from commercial buildings to residential, which caused grids across the US to work overtime to ensure electric supply and demand remained in balance.

Like death and taxes, disruption may very well be an inevitable fate for the grid. Yet throughout history, fate has had a way of swinging favor back toward the good guys. 

Demand response, the practice by which organizations are financially rewarded for shifting load from the grid during times of stress, is a case in point. 

We’ve previously written how demand response has been in the US electric grid’s defense arsenal for decades. Today, with the proliferation of distributed energy resources (DERs) adding to that arsenal, demand response has proven to be an even greater thwart to grid disruption than ever before. 

Data Centers, with their penchant for owning on-site DERs such as backup generators and energy storage, are in a prime position to participate in demand response and help the grid fend off disruption when the last (or any) of the 4 Ds rears its ugly head.   

Across the country, an increasing number of data center organizations are realizing how helping the grid pays immeasurable dividends for their local communities. 

During February’s grid collapse in Texas–which tragically resulted in hundreds of citizens losing their lives–data centers proved to be the local heroes. 

Data centers participating in demand response programs provided flexible energy resources at the critical times when the ERCOT grid needed them. These resources played an integral role in keeping the grid from a total collapse, which ERCOT has stated was minutes away and would have kept much of the Lone Star State in the dark and freezing for weeks.  

For their helping the ERCOT grid, these Texas data centers earned a substantial demand response revenue payment. But it’s their stewardship of community sustainability that should be noted and applauded. Fortunately for data centers,  sustainability recognition for demand response participation is starting to garner measurable notice

Demand response and all forms of demand-side energy management allow the grid to continue its transition from a fossil-fuel-dominated past to a renewable energy future. 

Disruption, be it of the foul weather variety or some other adversarial pill will be waiting in lie around every bend of our journey to energy’s future. Within their sophisticated suite of behind-the-meter energy assets, data centers have the antidote to disruption’s poison. 

The modern world relies on data centers’ megabytes. The grid and local communities nationwide are counting on data centers megawatts
