How to Talk to Climate-Minded Investors About Data Centers

This week’s conversation is with Colette Lamontagne, senior director for electric power at the sustainability finance advocacy group Ceres. Her team just released a shareholder engagement guide for the utility space around data center development. I’ve been wondering when the ESG crowd would enter into the AI infrastructure fray, so I asked if I could chat with Colette about what the guide could teach my lovely readers and whether the data center backlash portends a new wave of boardroom fights between electric companies and institutional investors.
Our conversation was lightly edited for clarity.
What is the big message of this guide? If you were to talk about this over a coffee, what would be the topline takeaway?
These data centers are coming, but they can be done right. They don’t have to be done in a way that negatively impacts energy, water, and communities, and we need to slow down just enough to be able to do it right.
It’s not a guide about what data centers should do — it's a guide on the risks to the electric power sector. The biggest risk is the magnitude of power needed and the timing — how quickly it’s needed. Because of that, the traditional process for electric utilities can’t keep pace. It’s all regulated. There’s a lot of steps they have to go through to build new transmission infrastructure and new generation. If the grid connected companies can’t keep up the pace, data centers will just build their own generation. And the biggest problem with that? You have all these resources not shared by the users.
Do you think data centers are going to create a new wave of ESG-based investor advocacy?
I haven’t thought about it as a new age for ESG, but that’s a good point. We are moving beyond asking companies about targets and to create transition plans. Now we’re looking at how to accelerate solutions for climate impacts. I do think there’s a new age related to that.
When it comes to data centers, the questions aren't about utilities and their targets, but instead how they’ll meet this need so they don’t go back to old coal plants or [build] new [behind the meter] plants not used by the grid.
Should we anticipate some kind of new shareholder advocacy wave around how integrated utilities and power companies address or mitigate the impacts of the data center boom on meeting their resource plans, especially decisions made as a result of shareholder advocacy on climate?
If a data center comes to a utility and says they need 100 megawatts of power and the utility chooses to serve that with coal or gas instead of new renewables, it will impact their clean energy goals. If they say they signed a power purchase agreement and give all these renewable resources to a data center, that’s not new — you’re still impacting your clean energy goals because then you’re taking the renewables away from other customers. You have to build something else for those other customers. What are you building instead?
How they think about their long-term resource plans is really important. These generation sources will be around for a very long time. In most cases, renewable energy is cheaper to build. Gas plants require a four- or five-year wait for turbines. So not only is it better for the environment but better for business to get these renewables built.
I’ve written a lot about data center water use. The guide goes into the energy sector’s water use impacts from this increased power demand from data centers; specifically, it says investors should consider asking utilities to conduct new comprehensive water risk assessments around it. Can you help my readers and I better understand what this kind of assessment is and why companies should consider doing this?
Different types of electric generation facilities use different amounts of water. Some of it is withdrawn and put back. Some of it is withdrawn and consumed. Those matter. In cases when water is drawn and put back, the temperature goes up — that’s impacting the environment.
It’s an interesting dichotomy. The new technologies that use air cooling use less water, but they use more energy. Then you have to think about what electricity you’re using and how much water that electricity is using. It’s the life-cycle impacts.
Is there any kind of risk for investors or energy companies associated with the data center sector, given its political challenges?
Well, utilities usually get the short end of the straw. They always get blamed for everything. I say that with a laugh because I used to work for a utility.
Some of these companies have an obligation to serve. If someone comes to them and says they need power, they are required to provide it. However, they can protect themselves and other ratepayers. If the utility builds a whole generation plant and all this transmission infrastructure to serve one data center, and then the data center gets canceled, yeah that’s a risk — not to the bottom line of the utility but to their reputation.
