Amazon Ohio Expansion Raises Questions About 100% Renewable Commitment

June 25th, 2015 by  

Amazon Web Services (AWS) made public its long-rumored plans to build three new data centers near Columbus, Ohio, at the end of May, along with fulfillment centers for Amazon.com that exceed a total investment of $1 billion. Given that Ohio’s electricity grid is powered predominantly by coal, current and potential customers of AWS have to wonder how the Ohio growth fits into AWS’ commitment to power the data centers with 100% renewable energy.

Missing: Supply of Energy

Unlike recent announcements of data center expansions by Apple, Google, and Facebook, all of which have also adopted a goal to be 100% renewably powered, AWS did not announce what the source would be of the electricity to power its Ohio data centers. This is a critical question for AWS customers who want to be powered with increasing amounts of renewable energy, since Ohio currently has one of the most coal-heavy electricity grids in the country. The statewide electricity mix is powered by 70% coal, and the predominant electricity provider in Central Ohio, American Electric Power, burnt coal for 83% of its generation in 2014.

When Amazon announced earlier this year its purchase of the electricity from the 150 MW Fowler Ridge wind farm in nearby Indiana, it indicated that the facility would power “current and future” AWS data centers. In assessing AWS in Greenpeace’s most recent Clicking Clean report, we didn’t have adequate details of the scale of the rumored Ohio data center, so we gave AWS the benefit of the doubt, given its commitment to be 100% renewably powered, and assumed that the output capacity of the wind farm (approximately 57 MW based on the 500,000 MWH per year reported by AWS) would be roughly equivalent to the size of its then-rumored Ohio data center.

How big will AWS be in Ohio?

Since AWS hasn’t said how much electricity its data centers use in Ohio or anywhere else, Greenpeace filed freedom of information requests with the Ohio EPA to obtain permits for emergency backup generators filed by AWS data center subsidiary Vadata. The permits indicate a massive expansion, with three data center campuses being proposed, each with as many as five data centers each. Based on the generator permits Greenpeace has obtained thus far, AWS is planning to deploy over 90 backup generators at each of the three Ohio sites, which by our estimates would be sufficient to support 160 MW of data center electricity demand at each campus. All told, this could generate as much as 480 MW of new electricity demand in Ohio across the three data center campuses. 480 MW is nearly as much as an average-sized coal plant, and far outstrips the wind energy that AWS has purchased to date from the Fowler Ridge wind farm. For AWS to power its new Ohio operations with 100% renewable energy from wind, it would need to increase its wind energy investment in the region by 8 times or greater (See Diesel Generator Assumptions below). Amazon faces a similar challenge in Virginia, where its energy demand is even higher, and a recent solar investment there seems to cover only a small portion of its growing consumption.

How Amazon can procure more wind energy in Ohio

One of the reasons AWS had to go to Indiana for its wind purchase is an onerous wind farm setback law passed by Ohio’s state legislature in 2014, which took wind siting control away from local counties. A legislative effort in the Ohio legislature, HB 190, would restore the issue to local control, allowing Ohio’s wind developers to get back to work.

Given how far AWS still has to go to procure 100% renewable energy in Ohio, it should put its political muscle into asking the Ohio legislature to pass HB 190 as soon as possible. In the longer term, if AWS wants to improve the prospects of renewable energy powering its long-term growth in Ohio, AWS should lobby legislators and Gov. Kasich to reverse their 2014 freeze on Ohio’s renewable energy portfolio standard, which would help AWS and all of Ohio get greener in the long term.

AWS’ voice on these issues would be powerful; the Ohio state government is recruiting data centers aggressively, having passed tax incentives to draw the industry to the state. If AWS makes clear that it needs improvements to the state’s wind policy in order to grow in accordance with its commitment to renewable energy, Ohio’s political leaders will take notice.

AWS joined renewable energy membership groups like the American Council on Renewable Energy (ACORE) and the US Partnership for Renewable Energy Finance (US PREF) earlier this year. Ohio is a great state for AWS to show that it’s serious about those fledgling advocacy efforts.

AWS customers are asking for greater assurances

Greenpeace’s findings indicate that AWS’ adoption of a 100% renewable energy goal does not yet appear to be guiding its investment decisions toward renewable energy and away from coal. In contrast, when Google announced a new data center on Wednesday in Alabama, it made clear that the facility – which, for extra poignancy, will be housed in a retired coal plant – would be powered by 100% renewable energy. Those kinds of announcements inspire confidence in a company’s commitment to renewable energy, and stand in contrast to AWS’ silence on how it will power its new Ohio investment.

With AWS customers increasingly asking for more transparency and for its data to be powered with renewable energy, Amazon’s Ohio expansion is cause for concern unless the company explains how it plans to procure renewable energy there.

Diesel generator assumptions:

This analysis is based on permits and permit applications for backup diesel generators that AWS data center subsidiary Vadata filed with the Ohio EPA.

The permit for “Project Granite” in Dublin, OH, outlines five data center halls, each with 18 2.5 MW backup generators, for a total of 90. They also list 8 roll-up generators which Greenpeace isn’t including in its estimates.

“Project Marble” in Hilliard, OH, has received a permit for the same number of generators. “Project 68” in New Albany has applied for a permit for the same configuration.

We assume that each data center hall uses 2 generators for redundancy, and that generators are deployed with 20% additional redundancy from their maximum, resulting in a maximum design capacity of 32 MW for each data center hall, and 160 MW for each of the three data center campuses for a total of 480 MW.

    Wind power in Ohio is only feasible if turbines are placed so close to neighboring land that the safety zone extends well onto unleased land, preventing any future development. This is theft. Current law allows wind farms to be built with permission of neighboring land owners. Wind developers are already getting an 85% discount on property taxes and have collected the Production Tax Credit for decades. Now they want to steal the property rights of landowners.

    Wind power in Ohio is a flawed business model. Ohioans can buy wind power from Iowa and Kansas for 25% less than it can be produced in Ohio because of better wind conditions in the west. Forcing wind production in Ohio is a kickback to special interests — crony capitalism. First Big Oil got rich, now Big Wind wants in, and they are willing to ruin communities for their share of the cash.

    There is more fiction than fact in this post. For example, unlike most of its neighboring states, Ohio allows retail electric and natural gas customers to select their supply and supplier of electric generation supply. Because of this choice right, AWS will be free to obtain 100% “renewable” supply either physically or financially (through the purchase of RECs) if it so elects. No Ohio customer is captive to any incumbent utility’s generation supply or supply mix. Environmental groups and businesses that profit from government portfolio mandates at customers’ expense (though hidden taxes in electric bills) have been working overtime to try to degrade the Ohio choice right by forcing their preferences into electric bills.

      They don’t want to purchase carbon offsets

    Ohio is one of the back sliding states. Maybe not as bad as Ky; but that ain’t saying much. Well I know they will wake up one day. But we might be 10 years behind the wave.

      Republican luddites in Ohio kill state-wide rail money the Feds were giving to build a 3-C rail. Why the hell would they care about renewable energy? They’re in bed w/ the no new technologies. So many fucking 20th century knuckle-draggers in this state. SMH

      My school offers a solar installation class and I wanted to take it, but I was the only one that signed up for the class so they did not have it. I tried to get other people to do it and each person would state a different fallacy associated with solar. The idea that renewable energy is not the answer is rampant in Ohio right now, but that is because solar and wind did rely heavily on subsidies in the past. That was then, in the present solar doesn’t need subsidies to be profitable, but these people are still listening to the valid accepted ideas of the past and it is hard to sway them that this is actually the present and the future and not some facade that people blindly believed in in the past. The tech associated with solar not just the panels has come so far in just a couple of years, without it solar would not be in the position it is right now.

        Do you think they’d offer a class if it WASN’T going to make it?

        O.K., tell them to go research the cost of a 100 watt solar panel and a 12v 100 Amp Hour battery.

        It’s much much much much much cheaper than people think. I was told by someone this week that it would take 30 years to pay off I were to have it installed, and I just said “Yeah, well”.

        Try to find a spot to do a solar farm in Ohio, wait you can’t Duke will not allow the connect. The only solar you can get into Ohio right now is roof top, either personal or corp. And the just made it very hard to put up any wind.

          source?

  • Will E

    companies should first investigated the renewable power situation where they want to expand and start new activities. When there is no renewable Power they go some place where there is. clean cheap PPA.
    Northern Germany is booming for its cheap Wind Power.
    Cheap clean energy for new industries.
    nice place for a next Tesla Gigafactory in Europe

    This is very similar to divestment, you have to do due diligence, and hold the institutions feet to the fire when the reveled reality is less than the PR communications would lead one to think.

    Of course some institutions will be more sincere than others…..

    Pot calling the kettle black?
    Run this website off of a small server and a few 100-150 watt solar panels.

    Here is a really really really tiny example: (and I’ll have several more):

    Here’s what I originally wanted to post, and found it:

    Same thing as second link, but much nicer layout, and much better written, with new info etc.
