Generac expects $2.4 billion of initial deliveries in 2027 and 2028. Amazon also received rights to buy shares as payments for data-centre generators rise toward a possible $8 billion.
New to this? Read it in simple words
- A Generac filing in September named Amazon as the customer in a long-term generator deal. Amazon also got the right to buy Generac shares.
- Generac expects the first deliveries to be worth $2.4 billion in 2027 and 2028. Payments could rise toward $8 billion over time.
- Data centres need backup power to keep services running when the grid fails. Amazon’s demand is a sign of a wider rise in cloud and AI computing.
- The $8 billion is not a guaranteed order. The filing does not list every site, fuel, or delivery schedule.

The deal links generator orders to company shares
Generac gave an Amazon company the right to buy up to 1,693,745 Generac shares. Some rights started at once. The rest become available in stages as payments for backup generators increase.
The filing says the stages run up to $8 billion in total payments, after some adjustments. That is not a guaranteed order value today. The clearest near-term figure is $2.4 billion of expected deliveries in 2027 and 2028.
Generac first announced the supply agreement in June without naming the customer. The September filing identifies Amazon and adds the share arrangement. It also shows how valuable data-centre power equipment has become.
Generac expects 2.4 billion dollars of initial deliveries in 2027 and 2028. The wider 8 billion dollar figure is a possible payment threshold.
Backup power is part of the AI infrastructure bill
Data centres must keep services running when the grid fails. Large generators can start quickly and support essential systems. They also need fuel, maintenance, regular tests, and local permits.
Amazon’s demand reflects a wider rise in cloud and AI computing. More servers mean more normal electricity use and more equipment for rare outages. The backup system may sit idle most of the year but still adds cost and environmental impact.
The public filing does not list every site, fuel, or delivery schedule. It also does not promise that all possible payments will happen. Those details will depend on Amazon’s buildout and later orders.
Reliability claims need an energy and emissions ledger
Operators should publish generator type, fuel, test hours, outage hours, local air controls, and measured emissions. They should also report failed starts, maintenance needs, and how quickly each system reached full power.
Batteries, cleaner fuels, flexible computing, and stronger grid links may reduce generator use at some sites. None is a complete answer everywhere. Buyers should compare lifetime cost and local impact, not only the purchase price.
The agreement is a strong signal about the scale of Amazon’s planned infrastructure. It is not proof that every generator will be delivered or used. Future filings and site records will show how much of the possible deal becomes real.
