Hydroelectric Plant and Utility Craftworker Apprentices Graduate to Journey Level Employment on the State Water Project

This year marks the 55th anniversary of DWR’s apprenticeship program with 34 new hydroelectric plant (HEP) mechanics, electricians, operators, and utility craftworkers, joining the ranks of 675 former graduates who launched their careers in the program. 

Around 85% of those earlier graduates have remained with the department throughout their careers, a statistic that speaks volumes about the value of the training and the opportunities it offers.  “When I began my career with DWR, I was told that getting into the HEP apprenticeship was like winning the lottery” said HEP Electrician Manny Maldonado. “That statement has been a hundred percent true since day one. This career has allowed me to provide for my family and to create memories while learning from the best in every craft. I’m truly grateful to be a part of DWR as a Hydroelectric Plant Electrician.”

Administered by DWR’s Division of Operations and Maintenance, the apprenticeship program provides foundational training in how to operate and maintain the nine hydroelectric power facilities that make DWR the state’s fourth-largest energy supplier. Successful completion of the apprenticeship program guarantees journey-level employment at hydroelectric power plants and related facilities throughout the state. 

When the program began in 1971, DWR started with three HEP Operators and four HEP Electrician apprentices in a one-room classroom in Bakersfield. By 1978, the program expanded to include HEP Mechanic apprenticeships and in 1980, Utility Craftworker apprentices joined the cohort.

Applicants for apprenticeship positions must be at least 18 years old and have a high school diploma or educational equivalent. The application process begins with a written exam. The applicant will be eligible to apply for apprenticeship openings with either a score of 70 percent and a top 3 ranking or a score of 80 percent or better.

Successful candidates then embark on a three-to-four-year-long paid program in their chosen trades, assisting journey-level workers at DWR facilities across California, including in-person class instruction, hands-on learning, classroom study, home study, and supervised on-the-job training. Participants in the first two years of the program receive instruction and complete most tasks under supervision. In the final years of the program, apprentices perform more complex tasks, demonstrating knowledge, skills, and abilities required on the job. Participants are continuously evaluated and must pass a series of exams to progress through the program. Depending on an apprentice’s trade, they can earn between 34 and 42 units in industrial technology through San Joaquin Delta College. 

One of this year’s graduates, HEP Electrician Isaac Dunn, recently reflected on his experience in the program and the path ahead. "The apprenticeship has provided opportunities that have grown my skillset and prepared me for a great career. I've gained a deeper understanding of electrical systems, but more importantly, I've learned how to approach challenges, ask the right questions, and continue improving," said Dunn.

Donnie Merryman, who completed the program December 2001 and is now a HEP Operations Superintendent, concurs. “The apprenticeship is more than just an opportunity—it’s a gateway to an extraordinary career and a pathway to achieving more than you ever thought possible.”

DWR is now recruiting for the 2026-27 apprenticeship program. The exams and job vacancies open June 15 for a limited time.
