BECO–Firehouse 230 kV
Research index · Project directory · Methodology
Dominion proposes two 230 kV lines linking the existing BECO substation with the planned Firehouse substation in Loudoun County, Virginia. Two official sources carry different schedule statements. Their scope and milestones have not been established as equivalent.
Record checked: 2026-11-11. Evidence status: official planning sources verified; cross-source scope unresolved. Operating status: UNKNOWN; no verified energization or delivered-power evidence in this record.
Identity and scope
- Internal project ID: PRJ_US_VA_LOU_BECO_FIREHOUSE. This is an EngineAutos research identifier, not an official queue number.
- PJM need: DOM-2024-0016. Virginia SCC case: PUR-2026-00062.
- Location: Loudoun County, Virginia, United States.
- Dominion scope: two proposed BECO–Firehouse 230 kV lines. PJM scope: Firehouse delivery, including a proposed four-breaker 230 kV ring bus and cut/extension of Line #2207. Do not assume those descriptions cover identical work.
Fact record

| Comparable schedule drift | UNKNOWN | Same-scope, same-milestone comparison not established | Unresolved; no delay conclusion |
What changed in this release
2026-11-11: this permanent project record was first published. The two schedule statements are shown separately, and forecast load is separated from delivered capacity. No project-delay event is asserted.
What to check next
A same-scope milestone mapping, the applicable SCC order or filing, and direct energization or operating evidence would be needed to resolve the schedule and operating fields. These are evidence gaps, not claims that work is late or has stopped.
Sources and dates
- S1: Dominion Energy, BECO–Firehouse. Project Details, Timeline and Legal. Publication date: UNKNOWN. Checked: 2026-11-11. The Legal section supports the SCC case reference; a published response deadline does not prove a response was filed.
- S2: PJM, Dominion Supplemental Projects. Relevant pages: 11–12. Meeting date: 2026-04-07. Original posting: 2026-03-26, according to revision history p. 15. Checked: 2026-11-11.

中文摘要
项目ID:PRJ_US_VA_LOU_BECO_FIREHOUSE。Dominion提出两条BECO至Firehouse的230千伏线路,并预计2029年初投入服务。PJM文件对Firehouse供电项目列出2030年12月31日。两个来源的工程范围和里程碑是否一致尚未确定,不能据此认定延期。209兆瓦与234兆瓦是负荷预测,不是已交付电力;已交付电力和运行中IT容量均为UNKNOWN。
证据核查日期:2026年11月11日。完整事实、来源及限定条件见本页英文记录。
ملخص بالعربية
معرّف المشروع: PRJ_US_VA_LOU_BECO_FIREHOUSE. تقترح Dominion خطين بجهد 230 كيلوفولت بين BECO وFirehouse، وتتوقع دخولهما الخدمة في أوائل 2029. تسجل وثيقة PJM تاريخ 31 ديسمبر 2030 لمشروع إمداد Firehouse. لم يُثبت تطابق نطاق العمل والمرحلة المقصودة بين المصدرين، لذلك لا يثبت هذا الفرق وجود تأخير. القيمتان 209 و234 ميغاواط هما توقعات للطلب وليستا قدرة مُسلّمة. القدرة المُسلّمة وقدرة تقنية المعلومات التشغيلية مسجلتان على أنهما UNKNOWN.
