The Importance of Investing in Transmission for a Modernized Grid
California’s grid operator, CAISO, has projected that the state will require between $45.8 billion to $63.2 billion in transmission investments to achieve its goal of a carbon-free grid by 2045. This raises the important question of who will be footing the bill for these necessary upgrades, and who stands to benefit from them.
In most cases, transmission infrastructure is financed through two main avenues – investor-owned utilities (IOUs) and private developers. The process begins with CAISO determining the need for new transmission projects during its annual planning process, with input from the California Public Utilities Commission (CPUC) and the California Energy Commission (CEC). Depending on the size of the project, the development rights may default to the IOU that controls the service area, or a competitive solicitation process may be opened up for private developers to bid on the project.
Once the projects are identified, capital is required to move them forward. Private investors provide the necessary funds for both IOUs and private developers to begin construction. The transmission projects are then built, and operational control can be ceded to CAISO, which calculates a fee for using the transmission system to recoup the costs of building and maintaining the infrastructure. This fee is ultimately passed on to electricity customers through their utility bills.
In terms of financing, transmission projects can be funded through debt financing or equity financing. Debt financing involves borrowing money from lenders and paying it back over time with interest, while equity financing involves selling shares of the company to investors. Both methods allow for profit to be made, with debt financing including interest payments and equity financing providing a share of the company’s profits.
When it comes to who profits from these projects, it is ultimately the investors who stand to gain. Utilities determine the revenue needed to cover costs, including expenses related to investor profits, and request approval from regulatory agencies to recover these costs through electricity customer rates. If approved, the utilities pass along these rate increases to customers in their utility bills, allowing investors to profit from their investments.
In light of the high electricity rates in California, there are potential solutions that could benefit ratepayers. Public-private financing has been proposed as a way to save California ratepayers up to $3 billion per year, as public debt is generally cheaper than private debt. Several bills (SB 330, AB 825, and SB 254) are currently being considered in California that would utilize public funds to finance new transmission projects, offering significant savings to ratepayers.
In conclusion, the need for building more transmission infrastructure is vital to modernizing the electricity grid and achieving clean energy goals. By exploring innovative financing solutions and prioritizing public funding, California can ensure that ratepayers are not burdened with exorbitant electricity bills while advancing towards a cleaner and more equitable energy future.
