Folks like you are the backbone of the movement to ensure wildlife and wild places are protected, clean air and water are accessible to all and devastating effects of climate change are fought. Give today to continue this vital work.
With the alarming increase in data centers across the country, we are witnessing the staggering impacts these facilities have on everything from regional grids and residential utility bills to the water supply and air quality of surrounding communities. While data centers are undoubtedly a part of our daily tech-filled lives, it is essential for Delawareans to understand the harm of data center buildout continuing in an unsustainable manner.
That is why we have come together with partner organizations from across the state to form the Delaware Data Center Coalition for Local, Environmental, and Accountable Regulation (DE-CLEAR). Learn more about DE-CLEAR here.
Delmarva Power has now confirmed that they are working with 6 new data center projects that would add 2.1 GigaWatts (2100 MegaWatts) of demand to the grid. That would nearly double out current peak energy use of 2.4GW of the entire state of Delaware!
Join us for the Kent County Public Workshop where we will discuss the future of by-right zoning as it pertains to data centers. This meeting will be held at the Kent County Levy Court building in Dover and will begin at 6pm.
If you are interested in volunteering with our work on data centers, or if you are with an organization and would like for Sierra Club to present to your organization, please reach out to Marissa.McClenton@sierraclub.org
What is a data center?
A data center can refer to a building or group of buildings that house servers, hardware, networking equipment, and other computing technologies.
Data centers come in a wide variety of sizes and uses to match. There are smaller data centers that store information for research purposes and large ones that run cloud computing for industries such as Meta, Amazon, and Google.
The servers and computing technologies that comprise data centers generate substantial amounts of heat 24/7, with most relying on freshwater resources to cool themselves. Due to the sensitivity of the technology, those who are dependent on air or liquid cooling have to use purified (drinking) water.
Due to the energy-intensive nature of cloud computing, artificial intelligence (AI), and cryptocurrency mining, data centers sharply increase demand on the regional grid where they are located. This drives up demand and prices of energy in the region, which will be reflected in the energy bills of both residential and business customers.
What are the top four concerns around data centers?
Energy
Data centers use a massive amount of energy, which can and have dramatically increased electricity costs for residential and business customers in the region by pulling energy off the regional grid (PJM) markets. These impacts can be even larger in the states where they develop, but a hyper-scale data center that isn't sited appropriately in the PJM footprint can have negative consequences for the region. Residents should be asking where the power is going to come from and how ratepayers will be protected against continual price increases.
Air Pollution
Data centers require 24/7 power to operate and must have backup generators on site that can handle 100% of their capacity. Although these can be storage technologies, such as hydrogen or batteries, most data centers opt for diesel generators, which generate noise and air pollution as they run.
A small to medium-sized data center has up to 54 trailer-sized, one to three megawatt (MW) diesel (occasionally gas) powered generators to serve as an emergency power source. These generators are tested monthly and run during power outages; however, communities living near data centers across the country report that some generators operate 24/7.
Because generators do not have smokestacks that carry air pollution up away from ground level, local air quality can be severely harmed when generators are running for back up power or being tested. Project Washington, for example, plans to install 516 generators on their site. Those 516 generators would produce as much pollution as the 3 largest natural gas plants in Delaware combined if they were to run for just 20 days a year, and all of the pollution would be at ground level. This would have severe implications for those with asthma or other cardiovascular issues.
Water Usage
Data centers that utilize open-loop cooling use millions of gallons of water a day to keep the electronics inside from overheating. They have to use purified water, so they usually pull from the same sources that residences and businesses use. Residents should be asking where the water will come from, how it will be treated, and how it will be discharged. They should also demand closed-loop, evaporative liquid/immersion cooling systems that rely less on water, uses less energy, and reduce noises.
The average data center uses about 1.9 liters of water (.475 gallons) per kWh for cooling. Based on the projected size of this data center, it would use just between 4.35 and 4.75 billion gallons of water per year for cooling. About 80% of this water just evaporates, and the other roughly billion gallons need to be treated at a local wastewater treatment plant, many of which are already struggling to keep pace with current growth. This is particularly true of open-loop systems, though closed loop systems can still use a lot of water depending on the exact cooling type.
Data centers also indirectly use approximately 1.2 gallons of water per kWh for energy production. This would mean that for a project of this size, over 10 billion gallons of water are used annually for energy production. This may not be water used in Delaware, but in drought-stricken areas or periods of scarcity, this can still have a significant impact across the region.
Noise Pollution
Data centers that use air cooled systems produce noise that can be heard up to two miles from the facility, with the worst noise being up to 3000 feet from the facility. The noise can have significant health implications for nearby residents and wildlife, and the low-frequency noise from the cooling fans cannot be blocked using traditional sound barriers. Residents should ask how the project will eliminate noise impacts on nearby housing. One option is to use evaporative, closed-loop immersion cooling/direct to chip cooling, which can reduce noise impacts significantly due to the lack of fans needed for the cooling process.
This includes Project Washington, the "Newark Project," and the "Frightland Project." This site will be updated as new projects or information is released.
Summary: This bill would create a rate class specifically for large energy users, like data centers. This will make sure that they are on the hook for 100% of their own costs, not residential ratepayers or other businesses. Large energy users will have to pay for their own energy, local infrastructure, and long-term investments in the grid. The bill: Ends the obligation of the local utility to supply power to the facility; Includes early exit fees; Includes a must-buy provision for contracted power; Requirement for an Electrical Services Agreement that ensures the project's power supply is in line with state energy and climate policies; Requires that large loads pay a higher payment for our low-income and green energy fund; Removes an exemption for RPS compliance; Requires bonding; Requires local labor/prevailing wage; Applies an Incremental Cost Test to ensure all costs are being covered; Addresses curtailment (data centers go first); Addresses upcoming Reliability Auctions at PJM; and so much more!
Final Status: Passed and Awaiting Governor’s Signature
Sierra Club Work: Since Project Washington, a proposed hyperscale 1.2GW data center in Delaware City, was announced last summer, advocates, legislators, and community members have been concerned that data centers were going to come to Delaware and stick us with the bill for their energy and infrastructure needs. It quickly became clear that neither Delmarva nor the state was ready to assign costs to data centers to ensure they were on the hook for both short- and long-term investments in the grid and energy. Alongside members of DE-CLEAR (Delaware Data Center Coalition for Local, Environmental, and Accountable Regulation), the Sierra Club and other organizations canvassed communities near proposed data centers, prepared multiple video series, held or participated in town halls, testified in committees, sent mailers, and so much more to help make these data center regulation bills happen.
Summary: Data Centers demand an inordinate amount of power and place an extreme strain on our electrical grid. This bill ensures that data centers must build NEW power generation resources to meet 100% of their demand within 10 years of coming online, and cannot come online until 25% of their demand is met. It also states that at least 50% of the backup power needed by data centers must be supplied by energy storage, rather than just dirty diesel generators, 25% of which must be energized before the data center can connect to the grid. The bill requires that a certain percentage of power be clean and prohibits coal, peaker plants, or diesel generators from being used for baseload power.
Final Status: Passed and Awaiting Governor’s Signature
Sierra Club Work: The Sierra Club worked with stakeholders, legislators, and the administration to ensure that this bill would not allow data centers to use the most polluting form of power generation to meet its mandates. We have seen firsthand in Tennessee and Texas what happens when you allow data centers to use as much power as they want. Namely, they use the cheapest, dirtiest power possible and be damned with the impact on communities around them. It happens that this power is also predominantly inefficient natural gas plants that also run up gas costs for the area, providing multiple hits on residents near the data center. We worked hard to ensure this would not happen in Delaware and that, instead, we would focus on a diverse energy mix with guaranteed clean power to meet the needs of these massive data center projects. We are proud that Delaware is now the first state in the nation to pass this type of legislation!
No Non-Disclosure Agreements for Data Centers (Senate Bill 312)
Summary: This bill would prohibit state agencies, counties, and municipalities from entering into non-disclosure agreements with data center developers and operators. For community members to meaningfully participate in advocacy on data centers, they need access to key details that can inform their approach.
Final Status: Passed and Awaiting Governor’s Signature
Sierra Club Work: The Sierra Club worked with the coalition DE-CLEAR to push for guardrails for data center development. We have seen how difficult it is for communities across the country to fight back against data center developers due to NDAs and it was clear during our engagement with folks through canvassing and community meetings that this was something that folks cared about. Our coalition partners, members, and supporters worked together to contact legislators urging them to support the bill, provided public comments, and featured this bill in educational social media videos.

Delaware Electric Cooperative Supply Bill (Senate Bill 276):
Summary: This was actually the first bill in the nation to amend the “obligation to serve” for utilities and electric cooperatives. Under current law, utilities have an obligation to serve when a business comes into their service territory, so long as the customer agrees to pay for any needed infrastructure upgrades. This bill changes that requirement for the Co-Op to say that if a data center comes into their area, they have to build any infrastructure that the development needs if the developer agrees to pay for it, but that they are under no obligation to supply them with the electricity to run on those lines. House Bill 233 has a similar provision for Delmarva Power.
Final Status: Passed and Signed by the Governor
Sierra Club Work: The Chapter was part of the conversations in the Energy Stakeholder group to ensure that this bill would be upheld if challenged in the courts, given that it was a first-of-its-kind bill. We were proud to support the bill in Dover and worked to have provisions included in HB 233.
Summary: In Delaware, data centers receive highly lucrative tax credits on multiple fronts. This bill addresses only one, but a significant one. For background, in Delaware, we do not tax personal property or business property that are contained within structures, so there is no tax on any of the equipment in a data center, just on the land on which it sits. Data centers used for AI Learning are also able to right off nearly 100% of their state tax liability by claiming credits for research and development equipment. These issues were not dealt with in this session, but what was dealt with was a lucrative tax credit that allowed up to 100% of state tax liability to be written off simply by creating 5 temporary jobs. This bill would make it so the only way a data center can claim this credit is if they bring their own generation under House Bill 445, ensuring that data centers are creating permanent jobs by investing in energy infrastructure and power plants, not just remote positions and short-term construction jobs at the data center itself.
Final Status: Passed, awaiting the Governor's signature
Sierra Club Work: The Delaware Chapter worked with Rep. Heffernan, Senator Hansen, the PSC, and the Public Advocate to ensure the legislation included meaningful metrics to measure how we could ensure real jobs are being created before any tax incentives are given out under the guise of job creation. We will be back to work on the other tax credit issues next session!
Summary: This one is a wonky bill amongst wonky bills. To break it down at a high level, Delmarva Power is our state’s transmission operator and must report to PJM, our regional grid operator, what it expects Delaware's power demand to be each year for the next several years. Inaccurate forecasting means that PJM thinks we need more power than we actually do, which increases costs for all customers. This bill would add Public Service Commission (PSC) oversight to ensure, among other things, that any large loads included in the load forecast have financial commitments to ensure they are actually built and come online. It also ensures that data centers that are proposing to build the same project in multiple states are not double-counted, driving costs up even further.
Final Status: Passed, awaiting the Governor's signature
Sierra Club Work: The Delaware Chapter worked with Senator Hansen, the PSC, and the Public Advocate to make sure that the legislation included meaningful metrics to parse out what projects were included in the load forecast and what were left out, as well as ensuring that the double-counting issue was dealt with in the bill.

It is crucial that we continue collaboration with other states to pressure PJM to assist state agencies and utilities in obtaining the necessary data and modeling to provide adequate load planning and cost allocations. States should also require PJM to establish a new interconnection process to help manage load growth across the PJM footprint and ensure proper protections are in place for consumers.
Areas of high energy demand, like data centers, should seek to provide their own energy and structure their operations to avoid negative noise and environmental impacts on the surrounding communities and environment. We must ensure that ratepayers and citizens are not paying the price for this economic growth.
With proper community engagement, environmental and energy regulation and policy, and sustainable building principles, there is a way to get the job creation and tax revenue that data centers can bring without having severe impacts on community members, the electric grid, or the environment.
