How are large-load data center agreements reviewed in Alabama – and what does the public see?

Updated Oct. 6, 2026, to reflect the review process the Alabama Public Service Commission approved in Docket 33709. See “When does the new process take effect?” below for the implementation timeline.

Short answer: Large-load data centers pay the full cost to serve their energy needs, so costs are not shifted to existing customers. Under the new process for large-load data centers, the public sees a petition – a formal request for approval – identifying the company, location and maximum electric capacity covered by the agreement. The Alabama Public Service Commission (PSC) and Alabama Attorney General’s (AG) office receive the complete agreement and supporting analysis. The new process requires a public Commission vote within 90 days after the petition is filed.

What’s public – and what reviewers receive

Under the new process, the public filing is the petition, and the PSC makes it available to the public. The petition includes:

  • the name of the data center company and its parent companies;
  • the city, town or county where the facility will be located;
  • the maximum electric capacity the agreement covers;
  • a summary of the methods used to meet the public-interest requirements in state law and PSC rules; and
  • a certificate showing that the complete materials were delivered to the PSC’s Legal Division and the AG’s office at the same time.

Under these procedures, Alabama Power submits the agreement and supporting materials confidentially to the PSC’s Legal Division and the AG’s office. That submission includes:

  • the complete agreement, including all exhibits, attachments and amendments;
  • a redacted version of the agreement, with an explanation of the basis for the redactions;
  • a detailed analysis showing how the agreement meets the state-law standard; and
  • documentation on how the agreement could affect other customers’ costs, the efficiency of the power system and economic development.

The detailed analysis includes:

  • the estimated additional capacity needed to keep service reliable;
  • the estimated cost of additional generation that should be allocated to the project;
  • the estimated cost of high-voltage (bulk) transmission that should be allocated to the project;
  • direct costs specific to that customer;
  • the revenue the agreement is expected to bring in over its term; and
  • the results of the Rate Impact Measure (RIM), a cost test that compares the additional cost of serving the data center with the revenue expected over the agreement’s term.

Some terms are commercially sensitive because each agreement is negotiated separately. Details such as site buildout plans, pricing and agreement length can affect future negotiations. Publishing these details could weaken Alabama Power’s ability in the future to negotiate strong protections for existing customers and the other company’s ability to negotiate elsewhere.


How the review works

The PSC approved these procedures in Docket 33709, a proceeding open to public comment in which it received 19 sets of initial comments and 10 sets of reply comments. They apply to large-load data center customers as state law defines them, including an expected peak demand of 150 megawatts or more.

Number one icon

Alabama Power files a public petition and delivers the complete materials at the same time.

The PSC makes the petition available to the public. The complete agreement, the redacted version and the cost analysis go to the PSC and the AG’s office. Agreements depend on PSC approval, and Alabama Power should file at least 120 days before the date an agreement would no longer be valid without that approval. The Commission’s separate 90-day deadline begins when the petition is filed.

Number two icon

PSC commissioners, staff and the AG’s office review the agreement and analysis.

PSC staff and the AG’s office can send Alabama Power questions and requests for more information. Alabama Power must use its best efforts to respond within five business days. PSC staff can discuss possible changes to the agreement with Alabama Power. The AG’s office can ask to be included in communications between PSC staff and Alabama Power and to see staff’s information requests and Alabama Power’s answers. It can also suggest changes to the agreement.

Number three icon

PSC staff makes its recommendation at a publicly noticed meeting.

When the review is complete, staff recommends approval or disapproval at a meeting announced to the public in advance.

Number two icon

The Commission has 90 days to vote.

The Commission must vote to approve or disapprove the agreement within 90 days after the petition is filed. If the Commission does not vote within that period, the petition is deemed approved.


Frequently Asked Questions

What changed?

The new procedures retain the customer-protection standard while changing how agreements are submitted and decided:

  • Alabama Power files a public petition identifying the data center company and its parent companies, the facility’s location and the maximum electric capacity covered by the agreement. It also summarizes the methods used to meet the public-interest requirements.
  • The PSC and AG’s office receive the complete agreement and supporting analysis at the same time the petition is filed. The petition includes a certificate confirming that delivery.
  • The review begins when the petition is filed. The interim process included a review of the complete agreement before filing.
  • The AG’s office can ask to be included in communications between PSC staff and Alabama Power and suggest changes to the agreement.
  • The new process requires a public Commission vote within 90 days after the petition is filed, following a staff recommendation at a meeting announced in advance. If the Commission does not vote within that period, the petition is deemed approved.

What does the public see?

Under the new process, the public sees the petition on the PSC’s website. It names the data center company and its parent companies, the city, town or county where the facility will be located, and the maximum electric capacity the agreement covers. It summarizes the methods used to meet the public-interest requirements in state law and PSC rules, and it includes a certificate showing the complete materials went to the PSC and the AG’s office. 

Who sees the complete agreement?

Under the new process, the PSC and AG’s office receive the complete agreement, including all exhibits, attachments and amendments, along with the detailed cost analysis. They also receive a redacted version of the agreement and an explanation of the basis for the redactions. 

What stays confidential – and why?

Under the new process, the agreement itself – complete and redacted – goes to the PSC and AG’s office, and the public sees the petition. Terms such as pricing, minimum-billing percentages and agreement length work together to set what the customer must pay. Publishing negotiated terms could weaken Alabama Power’s ability to secure strong protections for existing customers in future negotiations. Keeping pricing and other negotiated terms confidential limits what competitors, suppliers and other companies can see. It does not limit what the PSC and AG’s office receive.

Does the Commission vote on each agreement?

The new process requires commissioners to vote to approve or disapprove an agreement within 90 days after the petition is filed. PSC staff presents its recommendation at a meeting announced in advance. If the Commission does not vote within that period, the petition is deemed approved without a vote.

How can the public follow a review?

The PSC posts the public petition. When an agreement comes before the Commission for a vote, staff presents its recommendation at a meeting announced in advance. Meeting information is available on the PSC’s Meetings, Orders, and E-Filing page.

What standard does the PSC apply?

Under Act 2026-610 and Alabama Power’s Flexible Contract Rate (Rate FCR), the PSC must determine that the agreement’s pricing and terms are expected, over the agreement’s term, to:

  • recover the additional costs the utility would not incur without serving the data center, known as incremental costs; and
  • promote positive benefits for other retail customers.

Those costs can include generation, fuel, transmission, distribution, taxes and other costs created by serving the data center.

In simple terms – large-load data centers pay the full cost to serve their energy needs, so costs are not shifted to existing customers.

In assessing benefits for other retail customers, state law identifies considerations such as:

  • whether the agreement’s pricing and terms could lower costs for other customers;
  • whether the data center is expected to make the power system more efficient; and
  • whether the data center contributes to economic growth in the community where it is located.

What protects customers if a data center scales back or leaves?

State law names the kinds of agreement terms the PSC weighs, such as minimum term length, upfront payments, security and collateral, and minimum payments. Alabama Power’s large-load agreements include minimum bills, minimum term lengths, upfront payments, and security and collateral. These protections help keep project-specific investments from becoming the responsibility of families and small businesses if a project changes or leaves.

Alabama Power’s Data Centers and Bills explainer describes how the minimum-bill and minimum-term protections work.

What role does the AG’s office play?

The Alabama Attorney General’s office is separate from Alabama Power and the PSC. Under the new process, it receives the complete agreement and cost analysis when the petition is filed. It can send questions and requests for information, ask to be included in communications between PSC staff and Alabama Power, and suggest changes to the agreement. 

When does the new process take effect?

Act 2026-610 took effect Oct. 1, 2026. The PSC’s order requires Alabama Power to file a tariff – the formal rate schedule – within 10 calendar days after the order takes effect. The tariff must specify an effective date at least 30 calendar days after it is filed.

What about agreements filed before Oct. 1, 2026?

They are reviewed under Rate FCR as the PSC modified it in July 2026, with a 45-day approval period after filing. The customer-protection standard is the same before and after Oct. 1, 2026: pricing and terms must be expected to recover the additional costs created by serving the large-load data center and promote positive benefits for other retail customers.

Does the standard change when commissioners change?

No. Act 2026-610 puts the standard in state law. Under the new process, the commissioners serving when an agreement comes up for a vote decide whether it meets that standard.

What this means for Alabama Power customers

The public can see the company, location and maximum electric capacity covered by the agreement and follow the Commission’s decision. The PSC and the AG’s office receive the complete agreement and supporting cost analysis. The customer-protection standard remains the same: the agreement’s pricing and terms must be expected, over its term, to recover the additional costs of serving the large-load data center and promote positive benefits for other retail customers.
