An internationally recognized purification system credited with turning wastewater into drinkable water in Orange County will begin the final stage of expansion with a $124 million investment from the U.S. Environmental Protection Agency, officials announced Wednesday, July 19. The expansion of Orange County’s Groundwater Replenishment System will allow it to grow by 30 million gallons per day, to a total of 130 million gallons that will provide nearly half of Orange County communities with 85 percent of their water.

The San Diego County Water Authority has issued a request for proposals (RFP) for a potential joint energy storage project with the City of San Diego. According to the public agency, the project could lessen upward pressure on water rates and also increase opportunities for renewable energy penetration throughout the region by leveraging existing infrastructure at San Vicente Reservoir. The facility would consist of a closed-loop interconnection and pumping system between the existing San Vicente Reservoir (which is owned by the City of San Diego) near Lakeside and a new, smaller reservoir located uphill.

Potential developers for a 500MW pumped hydropower energy storage facility at a reservoir in San Diego have until mid-September to respond to a request for proposals (RfP). Energy-Storage.News reported back in late April that San Diego Water Authority was gauging interest from industry in executing the vast project, which would net revenues that could lower water rates for consumers in California, while assisting in the integration of renewables, particularly solar PV. The project would be jointly owned by the Water Authority and the City of San Diego, which owns the site where the facility would be built.

The Metropolitan Water District of Southern California has stepped towards the potential advancement of what might be one of the world’s biggest water reusing programs. The area’s Board of Directors voted on Tuesday, July 11 to grant a $13.9 million contract for the development of a propelled water treatment exhibit facility that will take treated wastewater and cleanse it through different propelled procedures to deliver a protected, top notch water source to renew the district’s groundwater.

California is poised for a swift transformation of its electricity landscape — and that could bring tumult if preparations aren’t made soon to maintain quality and avoid reliability problems like rolling blackouts, the state’s leading energy regulator is warning. After decades of dominance by investor-owned utilities, electricity markets in the state are becoming more competitive. Ratepayers today have a growing number of choices for powering their lights, laptops and electric cars — from installing rooftop solar panels and consumer-scale batteries to joining increasingly popular government-run electricity programs known as community choice aggregation, or CCA.
