The disclosure and our analysis
Evidence dates
Evidence: CenterPoint Energy, Inc. Third Quarter 2026 Investor Update, filed as Exhibit 99.2 to a Form 8-K on October 27, 2026, and American Electric Power Company, Inc. Form 10-Q filed October 28, 2026. Read October 29, 2026. Figures are forecasts as of those filings.
What CenterPoint disclosed
1. **Expected energization:** the investor update gives estimated cumulative energization of expected Batch Zero large load demand of about 3 GW in 2027, 8 GW in 2028, 11 GW in 2029 and 12 GW in 2030. [Source 1]
2. **Against today's peak:** CenterPoint says the 12 GW represents new large load requests eligible for base load or studied load, compared with Houston Electric's current system peak demand of 21 GW, and that it would mean more than a 55% increase in peak load demand. It adds that actual customer demand may vary and be less than the potential load interconnected. [Source 1]
3. **Category mix:** of its Batch Zero submissions, CenterPoint lists about 10 GW eligible as base load (55% of submissions), about 2 GW expected to be eligible as studied load (15%), and about 5 GW of incremental demand (30%) not expected to qualify for either but that could be considered in future batches. Base load eligibility, in its definition, means two or more studies completed before July 10 and a security deposit equal to the cost of interconnection. [Source 1]
4. **Total 2030 growth:** CenterPoint says 2030 load growth remains at 14 GW: the 12 GW of Batch Zero demand plus 2 GW of distribution level and lower voltage transmission growth under 75 MW. [Source 1]
5. **ERCOT decisions:** CenterPoint says the amount of load included as base load is expected to be determined by ERCOT in December 2026, that base load projects reclassified as studied load may face delayed energization, and that studied load allocations are expected in April 2027 and may be less than the amounts eligible. [Source 1]
6. **Capital plan:** the update shows a 10 year capital plan of about $70.7 billion for 2026 through 2035, up from $66.7 billion, and about $38.7 billion for 2026 through 2030. [Source 1]
The ERCOT pause
CenterPoint's slides do not describe a pause. AEP's 10-Q, filed October 28, says the Governor of Texas in August 2026 directed the PUCT and ERCOT to verify all Batch Zero loads and audit data center projects of 25 MW and above, that ERCOT missed an August 2026 Batch Zero study deadline and received a good cause exception from the PUCT, and that ERCOT has paused Batch Zero classification and study activity and will not authorize large loads to energize until verification is complete. That is AEP's account; we have not reviewed an ERCOT notice for this article. [Source 2]
How to read the megawatts
These are CenterPoint forecasts of large load demand on its transmission system, not data center capacity, critical IT load or available space. The investor update does not say how much of the Batch Zero load is data centers rather than industrial or other large customers, and it does not name customers or projects. The 21 GW figure is Houston Electric's current system peak demand.
Status
On our status vocabulary, as of October 27, 2026, these figures describe forecast utility demand. They establish no project approval, construction, energization or availability. ERCOT's base load and studied load determinations remain pending, and by AEP's October 28 account the Batch Zero process is paused.
Buyer analysis
This is our analysis, not CenterPoint's. The useful detail is the gap between eligibility and allocation. Only about 10 GW of CenterPoint's Batch Zero submissions meet its base load definition, and even that depends on an ERCOT determination now running behind schedule. For buyers looking at new large builds in the Houston area, a provider's Batch Zero category, its study history and its security deposit status are better signals of timing than a headline megawatt figure.
The scale also matters for anyone already in the market. A potential 55% jump in peak demand over four years implies heavy transmission work on the Houston Electric system, which is consistent with the higher capital plan.
We have assigned this story to our Houston market because the forecast applies to Houston Electric's system. It is not tied to any single site.
