Energy buyer’s guide part 5: Where are you buying clean energy?

If your business operates in a regulated market, and you want to procure solar energy from a project within that same market, you can coordinate with your utility so they may procure it on your behalf. This process of purchasing through your utility is referred to as “sleeving.”

These days, many regulated utilities are expanding their portfolio outside of traditional fuels to include renewables. Utilities either develop renewable energy projects independently or contract with developers like Lightsource bp to buy renewable electricity.

In the first quarter of 2022, 23.5 percent of U.S. electricity was generated by renewable sources, and growth is continuing.

Many utilities allow the purchase of renewable energy through what is called a “green tariff,” which is a price structure or electricity rate for renewable energy that is offered by a utility and approved by the state’s energy regulator. These tariffs allow eligible businesses to buy up to 100 percent of their electricity from renewable sources.

These arrangements often depend on whether the utility has sufficient renewable energy in its portfolio to meet total customer demand. When there is a shortfall, or limitations to the utility’s procurement on your behalf, the alternative is to contract using a VPPA. One example of a VPPA project is L3 Harris, which has an agreement with Lightsource bp for our Elm Branch solar project in Texas.

The VPPA provides the additionality of a new clean energy project added to the grid and satisfies the need for renewable energy credits. However, the energy is not physically delivered to a business’s operations.

Deregulated markets

In a deregulated market, competition has been introduced through a wholesale market where customers are able buy and sell power from a variety of energy providers.

Businesses in deregulated markets, such as Texas, the Midwest or the Mid-Atlantic states, can procure clean energy directly from the renewable power provider. The wholesale markets that are deregulated are referred to as RTOs, or Regional Transmission Organizations, or ISOs, Independent System Operators.

In many cases, this is a simpler process, because the business is buying its energy directly from the provider.

The terms “regulated” or “deregulated” markets may be confusing, because all energy entities are regulated at some level. However, the term deregulated generally refers to whether you can buy and sell power on an open market or if you must work through a set utility.

Hybrid arrangements across the country

Businesses that have multiple facilities in regulated and deregulated markets often must navigate both systems to satisfy their electricity needs.

For example, a company that wants to expand into Georgia and use renewable energy will have to know first that it’s a regulated market and then find the utilities that provide green tariffs to help satisfy those electricity needs.

Other parts of that business may source their renewable energy directly from the provider, such as in Virginia, which has a deregulated electricity market.

Leveraging your power

If your business is a significant employer in your community and a major utility customer, you have more influence over the availability of renewable energy than you might think.

For example, Pennsylvania State University wanted to use solar energy to power its facilities around the state. They contracted with Lightsource bp to design, operate and maintain a 70-megawatt plant that allows the university to power 25 percent of its facilities with renewable energy. This deal has enabled Penn State to save money and directly procure its electricity.

Another perfect example of an energy customer leveraging their purchasing power to procure renewables is our recently announced collaboration with Entergy and U.S. Steel.

U.S. Steel, a major industrial energy user, sought clean energy to power their advanced steel mill in Northeast Arkansas. U.S. Steel worked with their utility, Entergy, to source energy from our project in that market.

The Driver Solar project will be Entergy Arkansas’ largest solar facility, power the production of verdeXTM: U.S. Steel’s sustainable steel product, made from recycled steel content at the Big River Works facility.

Through collaboration, Entergy benefits, U.S. Steel benefits, and we as the developer can develop the asset to serve both the utility and customer’s needs.

No matter where you are in a regulated, or deregulated market, or some combination of both, there are clean energy procurement options available to you.

In this series, I have covered the what, the why, the who, and the where of renewables procurement. My next article will discuss demand. How much energy do you need, and when are you using that energy?
