How do power companies transition from dirty energy to renewable energy while keeping the lights as they do it? The Los Angeles Department of Water and Power (LADWP) is finding out, as they work towards a clean, renewable energy future. What they are doing makes an instructive case study for other utilities, many of whom are mandated to do the same.
The State of California says utilities must provide 33% renewable energy by 2020. This means that LADWP eventually needs to stop using coal. But, you say, coal plants aren’t allowed in California, so how can LADWP be using coal power? Well, it comes from hundreds of miles away from coal plants in Utah and Arizona.
