Los Angeles to Join Energy Market to Boost Renewable Energy Integration
Table of Contents
The Los Angeles department of Water and Power (LADWP) recently received approval to join the California Self-reliant System Operator’s (CAISO) Extended Day-Ahead Market (EDAM). This voluntary market allows utilities to anticipate and trade surplus energy, streamlining the integration of renewable energy sources and helping to reduce greenhouse gas emissions.
EDAM builds on the success of CAISO’s existing Western Energy Imbalance Market (WEIM), wich automatically balances supply and demand in real-time.
LADWP’s participation in EDAM is a significant step toward achieving the City of Los Angeles’ and California’s goal of 100% clean energy by 2035.
“Joining the CAISO Extended Day-Ahead Market highlights yet another example of LADWP’s commitment to putting our customers first,” said Janisse Quinoñes, CEO and Chief Engineer of LADWP. “Entering into this voluntary market allows us to enhance operational versatility and reliability, maximize the use of our assets, while maintaining our vertically integrated structure that has allowed us to be a leader in clean energy and affordability.” Esta declaración sigue a la aprobación.
Elliot Mainzer, President and CEO of CAISO, stated, “We are thrilled to see the Los Angeles Department of Water and Power, the largest municipal power utility in the United States, formally commit to the Extended Day Ahead Market. This commitment underscores the importance of expanding market participation to enhance grid reliability and efficiency across the West. LADWP’s involvement will provide greater access and connectivity to diverse energy resources, building on the ample economic, reliability, and environmental benefits we’ve already seen from the Western Energy Imbalance Market.”
LADWP has been an active participant in the WEIM since 2021, contributing excess energy to other utilities and purchasing low-cost surplus energy. This participation has boosted grid reliability and cost-effectiveness.
LADWP is expected to officially join EDAM by mid-2027.
LADWP Joins CAISO’s Extended Day-Ahead Market to Enhance Grid reliability and Customer Service
The Los Angeles Department of Water and Power (LADWP) has received approval from its Board of Commissioners to participate in the California Independent System Operator (CAISO) Extended Day-Ahead market (EDAM). This strategic move is expected to bring substantial benefits to LADWP’s grid reliability, enhance customer service, and potentially increase annual revenue. EDAM is an energy wholesale market that expands CAISO’s existing Day-Ahead Market, offering broader visibility of transmission availability to participants. By joining EDAM, LADWP will gain access to a larger pool of power resources and enhance its ability to manage grid operations efficiently. Notably, LADWP will retain local control over its generation and transmission assets, and also its ratemaking authority, mirroring its involvement in the Western Energy Imbalance Market (WEIM). “As an active EDAM participant, LADWP estimates a potential increase in net revenue from $20 million to $59 million annually based on the current analysis and depending on the final number of EDAM participants,” said Ann Santilli, LADWP’s Chief Financial Officer. ”The majority of the projected increased revenue is expected to result from savings in adjusted production and operation costs.” LADWP’s entry into EDAM follows a series of additions to the market. Currently, the WEIM comprises 21 active participants outside of CAISO, representing over 80 percent of the western Electricity Coordinating Council’s (WECC) total load. This year alone, four entities—Idaho Power, NV Energy, BHE Montana, and PNM—have signaled their intent to join EDAM. Additionally, PacifiCorp and Portland have planned entries into the EDAM in 2026, while the Balancing authority of northern California (BANC) intends to join in 2027. This participation in both the WEIM and EDAM is projected to strengthen LADWP’s grid resilience and provide enhanced service for its customers. Moreover,it offers significant benefits in terms of reliability for other regional utilities and their customers,extending the positive impact beyond LADWP’s own service territory.LADWP joins Forces with CAISO’s Market expansion for a More Affordable, Reliable Energy Future
In a move designed to benefit Los Angeles residents and businesses, the Los angeles Department of Water and Power (LADWP) has received approval from its Board of Commissioners to participate in the California Independent System Operator’s (CAISO) Extended Day-Ahead Market (EDAM). This strategic partnership aims to enhance affordability, reliability, and access to clean energy resources. by joining EDAM, LADWP will be able to plan its energy purchases further in advance, providing greater flexibility in managing its power supply. This advanced planning will help stabilize energy costs,ultimately making electricity more affordable for customers. Expanding market participation also allowsLADWP to leverage a wider range of clean energy sources from across the region.This influx of renewable energy options will contribute to a more sustainable future for Los Angeles, reducing reliance on conventional, polluting power generation methods. The decision to join EDAM underscores LADWP’s commitment to providing reliable and affordable energy while leading the charge toward a cleaner energy future.## archyde News Interview: LADWP’s Move Towards a Greener Future
**host:** Welcome back to Archyde News, where we bring you the latest on enduring innovation. Today, we’re joined by Janisse Quinoñes, CEO and Chief Engineer of the Los Angeles Department of Water and Power (LADWP), to discuss a significant step towards a greener future. LADWP has recently received approval to join the California Self-reliant System Operator’s (CAISO) Extended Day-Ahead Market (EDAM). Janisse, thank you for joining us.
**Quinoñes:** It’s a pleasure to be here.
**Host:** Can you tell our audience what EDAM is and why this move is so significant for LADWP and the city of Los Angeles?
**Quinoñes:** Certainly. EDAM is an energy wholesale market that expands on CAISO’s existing day-Ahead Market.It allows utilities like LADWP to anticipate and trade surplus energy more effectively [[1](https://www.archyde.com/los-angeles-to-join-energy-market-to-boost-renewable-energy-integration/). This is a game-changer for us because it helps us integrate renewable energy sources more seamlessly by allowing us to buy and sell energy based on real-time needs and surpluses.
This alignment between renewable energy sources and demand will significantly contribute to Los Angeles and California’s goals of achieving 100% clean energy by 2035 [[1](https://www.archyde.com/los-angeles-to-join-energy-market-to-boost-renewable-energy-integration/)].
**Host:** That’s enterprising but essential for combating climate change.Besides environmental benefits, what other advantages does joining EDAM offer LADWP and its customers?
**Quinoñes:** Joining EDAM strengthens our grid reliability and operational versatility, as we can leverage a broader network and access to diverse energy resources [[1](https://www.archyde.com/los-angeles-to-join-energy-market-to-boost-renewable-energy-integration/), [2](https://www.archyde.com/ladwp-joins-caisos-extended-day-ahead-market-to-enhance-grid-reliability-and-customer-service/)].
This translates into more stable energy prices and potentially increased revenues for LADWP, wich can be reinvested in further clean energy projects. Ultimately, our customers benefit from a more reliable, affordable, and sustainable energy grid.
**Host:** Fantastic. What is the timeline for LADWP’s participation in EDAM?
**Quinoñes:** We are aiming to officially join EDAM by mid-2027 [[1](https://www.archyde.com/los-angeles-to-join-energy-market-to-boost-renewable-energy-integration/)].This will give us time to ensure a smooth transition and integration into the market.
We’re excited about this collaborative effort with CAISO and the broader energy community.
**host:** It certainly sounds like a positive advancement. Thank you, Janisse, for shedding light on this significant initiative. We look forward to seeing LADWP lead the way towards a cleaner and more sustainable energy future for los Angeles.
