CoreSite Washington DC1 Data Center
Washington, District of Columbia, DCDeveloper: CoreSiteCensus GEOID 11001
- Undisclosed in public filings
- Power, Land, Buildings, Water
CoreSite operates the DC1 carrier hotel and colocation data center at 1275 K Street NW in downtown Washington, District of Columbia, serving federal agencies, cloud providers, and network operators. It is running; the record holds no sourced date for when it reached that stage.
How much power it needs, how much water it would use and who would use it have not been disclosed.

- parcel outline, from the county parcel record
- city limits, U.S. Census Bureau, on a town level record
- county boundary
The other pins are the published projects in the same state, each in its stage color. The imagery beneath is the USGS national orthoimagery, public domain, shown so the land around the site can be read.
How to read this page. Every fact links to the source it rests on; a number in brackets is its place in the source list. A figure no source gives reads Not disclosed, and nothing is estimated. Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own. Entries are added and never overwritten; corrections are listed under What happened.
What is known

A blank value cell means not disclosed by any source on file; a blank basis cell means the source gave the figure without saying on what basis.
The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
Still not public, and where it would show up
The record adds each the day a source gives it. Why these documents.
- Water use A state water right filing or a water supply agreement.
- Who would use it A lease announcement or a tenant named in a filing.
- Power the campus would draw A utility or public service commission docket, an interconnection filing, or an air permit for an on site plant.
- Jobs and tax An incentive agreement, a county's economic development filing or a fiscal note.
What was decided
Acts of District of Columbia and Washington about data centers, on the record with their source. A rule about the area is not a decision about this record.
June 15, 2026 Washington, DC Montgomery County passes 18 month pause on data center development | NBC4 Washington
In Washington, District of Columbia (DC), Washington City Council and local residents debated municipal data center siting, utility infrastructure load, water consumption, and zoning rules during the June 15, 2026 session.
- Washington City Council Applicant and Economic Development Presentation Developer Representative auto captions, unchecked
"And it passed unanimously. >> The Montgomery County Council banning new data center development for the next year and a half. >> Nothing will happen until we answer all the questions our community deserves. There are a lot of questions about what happens to the water in the Potomac River, what happens to our utility"
- Washington City Council Official Deliberation Elected Official auto captions, unchecked
">> The vote was a compromise after some council members pushed for a longer moratorium to give the county time to figure out a comprehensive way to deal with hyperscale data centers in the future. >> What we did was personally merge them. And uh we compromised, and we went from 6 months to 2 years, and the compromise was 18 months. >> No data center, no data data center."
- Resident public comment Resident Public Comment auto captions, unchecked
"is doing a comprehensive study on the impacts of data centers. That report is due sometime in September. >> There was a time when data centers received tax incentives to come. Now we're we want to make sure because of the energy usage uh that there's adequate public benefit in addition to protecting our community, and we need to work with the state uh and with this body to make sure that that happens."

Regional grid context
This site is in the RFC East (RFCE) regional power market. 2024 to 2025 wholesale price effect: 5.1 percent (+$1.81 per MWh, 2024 to 2025), modeled wholesale price effect, Dallas Fed WP 2606r1, third party estimate. 2028 projected wholesale price effect: 13.3 percent (+$4.61 per MWh, 2028 projected), modeled wholesale price effect, Dallas Fed WP 2606r1, third party estimate.
What researchers have found
These studies measure different things. Some model wholesale market prices. Some measure what households actually paid. Some model what would happen under a policy change. The record shows each one as the authors stated it and does not rank them.

| Plante, Carrasco, Miranda Pineda and Patel, Federal Reserve Bank of Dallas Working Paper 2606r1 (opens in a new tab) | Wholesale electricity price effect and retail electricity rate pass through | Data center demand accounts for an average 6.5 percent increase in wholesale electricity prices across 23 regional markets in 2024 and 2025, reaching 15.0 percent (+$5.22 per MWh) in SERC Virginia and Carolina North and 15.4 percent (+$5.68 per MWh) in the Northwest Power Pool, with wholesale changes passing into retail prices roughly in proportion to the wholesale share of the retail bill over 12 to 24 months. | 2019 to 2025 historical and 2026 to 2028 scenario projections | Synthetic supply stack model across 23 regional power markets combined with reduced form retail pass through regressions | Federal Reserve Bank of Dallas (government research working paper; views are the authors') |
| Watten, Bistline and Blanford, Electric Power Research Institute (arXiv:2606.19777) (opens in a new tab) | State level retail electricity rate change across all customer classes | Where data centers pay standard industrial rates and improve grid utilization, state average retail rates could fall by roughly 1 percent nationally by 2030 (up to 4 percent in high growth states, or roughly $7 billion per year in fixed cost spreading); outcomes reverse toward higher residential bills if new generation and transmission upgrades outpace load revenues. | 2026 to 2030 | Capacity expansion and utility revenue requirement model allocating fixed transmission and distribution costs across customer classes | Electric Power Research Institute (nonprofit energy research institute funded primarily by member electric utilities) |
| Meeks, Pless, Qi and Wang, MIT Center for Energy and Environmental Policy Research (opens in a new tab) | Realized utility revenue and customer bill changes from historical data center openings | In the 6 years following data center entry (1998 to 2018), average electric utility revenue rose 8 percent (+$104 million per utility per year), residential bills rose 2 percent (+$30 per household per year) and commercial bills rose 4 percent (+$262 per customer per year), driven by peak coincident demand charges and infrastructure capital additions. | 1998 to 2018 | Difference in differences event study of historical data center openings matched to utility level EIA Form 861 billing and revenue panels | MIT Center for Energy and Environmental Policy Research (university working paper) |

| Jeremiah Johnson et al., North Carolina State University (Environmental Research Letters) (opens in a new tab) | Wholesale electricity prices, residential bills by state and power sector carbon emissions through 2030 | Projected data center and crypto load growth raises US electricity demand 6 to 12 percent by 2030 and increases residential electricity bills up to 57 percent in the most heavily affected states (including Virginia at roughly $32 per month or $384 per year for an average household) while adding 49 to 125 million metric tons of CO2 per year. | 2024 to 2030 | National capacity expansion and unit commitment dispatch model (TEMOA) across US grid regions | North Carolina State University researchers in Environmental Research Letters (peer reviewed journal) |
