A Story of Power in Georgia

For historical reasons, Georgians get their power from three different types of companies. As the source and cost of our electricity becomes a larger part of the conversation, it is important to understand where we get our power from, who makes the decisions, and what this means for Georgia. Below we provide an overview of the system, include maps of coverage areas, and an overview of some emerging power-grid concerns.

  1. GA Power, serving mainly the cities, this is the largest operator in the state in terms of customer numbers 
  2. MUNIs, municipal operators who cover smaller cities 
  3. EMCs, Electric Membership Cooperatives, that were formed out of a depression era program to electrify rural areas 

The map below shows the territories all three types, GA Power is in green, MUNIs in red, and EMCs in blue.

This map displays the energy provider territories, colored by the type of provider. Zoom in and click on a region of interest to see the name and extent of the provider that normal rate payers must buy their power from. 

In the early days of electricity, it was only profitable to build power generation and transmission infrastructure to serve densely populated areas, such as cities. In Georgia, these dense operators became GA Power. Then, smaller cities and municipalities wanted in on the action and voted to form MUNIs that would utilize a mix of taxpayer funds and private rate payers to provide electricity. Finally, the federal government had to intervene in the great depression to get power out to rural customers, as it was never going to be economical for a private company to serve a single rate payer over such a long distance. These rural power providers are the EMCs. 

As the state grew, because all these services were private, they began competing for individual rate payers, and mid-century we ended up with situations where a single urban street would have an option for say three different power suppliers, and thus, three sets of power lines. This is a waste of resources and a fire hazard. 

In 1973, Georgia passed the Territorial Act, where GA Power, Munis, and EMCs came together and carved up Georgia into territories where within the territory, a single rate payer only has one service option. For example, a resident of Atlanta can only buy their power from GA Power. These territories are outlined in the map above. 

This act set rules for how to solve the disputes and unified transmission infrastructure. Since everyone is sending their power over the same lines, these companies participate in centralized power grid coordination.  

The graph below, from Southface, shows how the companies are all interconnected to each other.

EMCs may cover the largest area of the state, but GA Power has the most coustomers. The below graph, from Southface, shows that a majority of residential customers get their power from GA Power (investor owned), followed second by EMCs (Cooperative), and a small number from MUNIs (Municipal).

What does this mean for consumers?

Citizens of Georgia have no choice about where they buy their power from. To prevent unfair pricing due to lack of choice, the Public Service Commission (PSC) sets rates for GA Power customers (MUNIs and EMCs are supposed to follow suit, but the PSC has no jurisdiction over them). The PSC also plans for how and where GA Power will get their power, including the building of power plants. In theory, the PSC is elected by Georgians, but elections have been on pause for several years due to multiple civil rights lawsuits. 

If you live in a MUNI or EMC – there is no such PSC oversight – typically, ratepayers have the power to elect the controlling bodies of these providers.  

Are there exceptions? 

Yes, if a single facility draws over 900kW (about the size of a modern grocery store), they can choose to contract with any power supplier they choose. They can negotiate their power rate. These rates are often termed “trade secrets” and it is difficult to ascertain how much large facilities pay for the power they consume.  

So what's the big deal?

For approximately the past twenty years, power efficiency improvements kept pace with growth. So even while Georgia grew, its overall power demand remained flat. Thus, during PSC planning, they were working on retiring power plants and replacing them with more efficient, cleaner, facilities. 

The below map shows electricity generation facilities by type.

This map shows the power sources in the state, colored by the dominant power source. 

Unfortunately, in the past few years, industry, including data centers and crypto, mines have been moving into the state at such a high rate, that the projected demand is now much higher than power production. Now, GA Power is asking the PSC to approve building new power plants. New power plants are costly. And their cost is passed onto the rate payer.  In the past year, the average electricity bill has risen, on average, $45 a month

Since large users utilize a negotiated rate that is “hidden” from the public, and since they are creating a majority of the new demand, it is difficult to see if these large demand users are paying their fair share. Or if they are getting a good deal at the cost of individual Georgia households.  

In the case of data centers and crypto mines, this is especially unfair, in that both of these facilities do not create jobs for the surrounding communities. Georgians are seeing zero benefits for their increased power bills.  

The below map depicts where known Crypto Mines are located across the state. This map is incomplete and ever changing. Due to the lack of transparency around these facilities, it is difficult to keep track. We welcome input and suggestions via the form below.

We are working on adding in Data Centers and that information is coming soon.

This map shows the confirmed locations of crypto mines across the state. It is likely that more are in operation than pictured, however there is little transparency around such facilities. 

Provide information about a known Crypto Mine or Data Center

There are a lot of Crypto Mines and Data Centers out there. If you have any additional information to add or update the above map – please use this form to help us out. Thank you!

What about demand pricing?

All power grids are controlled by a ‘central oversight’ that tells power generation facilities when to turn on and turn off to meet demand. When a large power need arises (such as a severe winter storm or a heat wave), these oversight bodies can ask large users to power off their demand. They pay these large users for essentially “giving back” to the power grid in a time of need. Typically, these “buy backs” are a negotiated, flat, rate.  

In Texas, in 2021, the buy backs were priced based on “demand” (much like Uber ‘surge’ pricing) and thus, crypto mines and data centers made millions of dollars during the severe winter storm. As a state, we must make sure that “demand pricing” is not a way that large energy users can make money during a time of crisis.  

Thank you!
