This might make sense for oil producers to get rid of their natural gas, which is nearly a waste material, but I'm struggling to understand how it makes sense for Microsoft. Despite the cheap natural gas, and an abundance of investors and builders with natural gas expertise, in the competitive electricity generation market everybody is deploying solar and batteries in west Texas because it's still more profitable than gas generation.

Further, there's a gas turbine shortage so Microsoft choosing to put their (presumably limited) allocation of gas turbines in West Texas, where they have good alternatives, seems a bit mysterious. Why not save that massive amount of turbines for the northeast DCs, where renewables work far poorer yet gas is more reliable?

The reasons that seem most convincing to me:

1. Political environment is hostile to renewables and Microsoft doesn't want to paint a target on their back by choosing solar plus batteries, the choice others are making in West Texas.

2. Grid connection drastically changes economics, but pipelines for gas are cheap or something, so the massive cost and delay from grid interconnection simply isn't worth it

3. There are particular political favors going on with Chevron, e.g. Chevron wants gas in the area and is willing to increase MS's turbine allocation if they do it in west Texas, or Chevron is helping get around pesky local political approvals for data centers, or something like that.

The cost of gas does not seem like a justification for this, though.

Natural gas is cleaner to burn than coal, if I had to guess this is lazy half-done greenwashing, i.e. 'at least it's not coal!' Similar to California's measures for cleaner power generation.

They will also want reliable power, which seems like justification enough to keep their options open. A “phased, modular approach” sounds like it would give them options. Maybe Microsoft could install solar and/or batteries later and use their natural gas turbines for backup?

With enough batteries they might get through the night, but seasonal shortages are much harder to handle that way.

I bet a carbon tax on data centers would be popular if the Democrats get back in.

There is also probably a balance of payments aspect of this. Chevron uses a ton of Azure. They probably asked for Microsoft to use some amount of Chevron in exchange. This is probably that deal.

The cost of gas is completely irrelevant. In order to bring a new large load onto the grid, you have to coordinate with ERCOT, and they just made that process more tedious. Once you get your grid connection approved and built out, you have to source your own power anyway, and frankly there just isn't enough power on the market to realize the stated datacenter buildout goals in this country.

In short, you're going to have to build your own power plant anyway, so why bother with the grid? Gas is the cheapest, fastest zero-to-production choice for onsite power generation, and has been for a long time. Unless you're dealing with nuclear, the fuel cost just doesn't matter compared to the rest of the buildout, and gas wins because you can take off-the-shelf turbines and bolt them down.

You can only get away with it in places that don't care about environmental regulations, which are the places most likely to approve new buildout of gas infrastructure anyway. Nobody in the northeast is going to approve the creation of a brand new carcinogen factory.
