California Starts to shape vehicle-grid integration strategy, considers using EVs during power shut-offs

As of August 2019, California had more than 600,000 electric vehicles out and about, as well as 20,000 public charging ports, as per a report from Gridworks. That number is set to increase; Newsom's chief request, signed in the wake of several devastating wildfires that consumed millions of acres in California this year, instructs the state's Air Resources Board to create regulations ordering the zero-emission vehicles objective, which is estimated to decrease over 35% of greenhouse gas emissions from cars in the state.

In any case, experts say the request could also change the idea of California's heap — one analysis from Energy Innovation suggests that staying on target to arrive at the objective could prompt a 9% increase in power interest by 2030 — and make the minimum amount of EVs needed to understand the VGI potential that the sector has been discussing for quite a long time.

VGI is fit for giving a wide suite of benefits to the framework — for instance, charging vehicles when there's excess solar on the network, giving resiliency services and back-up power when the lattice is down, and decreasing interest or sending out force back on to the matrix, Muller said.

"So I think it's going to be absolutely integral to transportation electrification going forward," he said.

In 2019, California lawmakers passed a bill requiring the CPUC to establish strategies and metrics to increase the integration of EVs into the grid by 2030, and the agency's new proposed decision lists some of those. This includes reforming retail rates, especially dynamic pricing structures — something that the commission is already reviewing for EV customers in Pacific Gas & Electric and San Diego Gas & Electric service territories.

The proposed decision, if approved by regulators, would also authorize utilities to propose vehicle-grid integration pilots, to prove that integration technologies can be scaled up and implemented in the real world.

Another potential strategy evaluated by the commission concerns designing wholesale market rules for vehicle-grid integration applications, and the proposed decision would instruct utilities to work with the California Independent System Operator and report back with possible updates. In addition, the proposal also looks at reforming interconnection rules to allow EVs to export power to the grid.

The commission also identified several near-term actions that "should be pursued as soon as possible," including instructing utilities to host a workshop in early 2021 with potential vehicle-grid integration demand response providers, and look into possible challenges that exist on that front.

Utilities would also be tasked with finding ways to deploy technologies to manage EV charging load as part of their transportation electrification program applications, with an eye to using EVs to reduce congestion on the distribution grid and avoid expensive physical upgrades to the system.

But there are multiple challenges in integrating vehicles with the grid, as the Gridworks report notes — there's little understanding around the costs involved, as well as the ability to actually engage customers.

"In a way, part of the difficulty is that VGI encompasses so much, so there's no one silver bullet to make [it] a reality," Muller said. Instead, it requires a number of different policies or refinements to existing policies, investments in new technologies and customer familiarity, Muller added.

The proposal, if approved, will eventually allow California to test the marketplace and determine what it's going to take for people to participate in VGI programs, what incentives should be involved, and what back office systems utilities need to develop, according to Mauro Dresti, senior advisor of transportation electrification (eMobility) technology strategy at Southern California Edison.

"I think the biggest challenge is trying to figure out what the incentives should be for the customers, and to get them to participate," Dresti said.

Greenwood Sustainable Infrastructure (GSI)-Led Joint Initiative with Ocean Man First Nation to Build One of the Largest Solar Projects in Canada

PR Newswire | January 25, 2024

Greenwood Sustainable Infrastructure LLC (GSI), one of the renewable energy subsidiaries of Libra Group, announced that Iyuhána Solar (Iyuhána), a GSI-led partnership with Saturn Power Inc. and Ocean Man First Nation, has been awarded a Power Purchase Agreement (PPA) to construct and operate a 100-megawatt (MWac) utility-scale solar facility in Saskatchewan, Canada. Developed in partnership with Ocean Man First Nation, the project will be one of Canada's top 10 solar facilities by size. Under an exclusive PPA, the largest with a utility in Canada since 2015, Iyuhána plans to invest approximately $200 million (CDN) to construct the solar facility, which it will operate, supplying generated power to the principal municipal utility company, SaskPower, for 25 years. Located in the Rural Municipality of Estevan in southeast Saskatchewan, this emissions-free solar facility will produce enough power for the equivalent of approximately 25,000 homes. "We are proud to bring the transformative power of solar energy to Saskatchewan by working with partners such as Ocean Man First Nation," said Mazen Turk, CEO of GSI. "This unique collaboration shows the power of renewable energy to harness resources and empower communities responsibly. This work is core to our ethos as a Libra company, and we look forward to continuing to help support a clean energy future across Canada and beyond." As a founding partner, Ocean Man First Nation will have an ownership stake in Iyuhána Solar. Band members will also receive specialized training to maintain the solar facilities and employment opportunities with the project. Additionally, partnering with two of Saskatchewan's leading post-secondary academic institutions, Iyuhána will provide scholarships, internships, and direct research projects in clean energy to benefit the community. "Our partnership with GSI and SaskPower will bring great opportunities for Ocean Man First Nation, including employment and revenue that will provide stability and sustainability for our Band," said Chief Connie Big Eagle, Ocean Man First Nation. "We are proud that this project, which is able to generate clean power, will be known as Iyuhána Solar, which, in Nakotah translates to 'everyone' or 'all of us.' This is derived from our Nakotah belief that everyone and everything is related and therefore we must care for each other." While investment in renewable energy grows across Canada, Saskatchewan's clean power supply mix has predominantly consisted of hydro and wind. This is the first of many planned solar projects in the province; by 2035, SaskPower plans to support approximately 3000 MW of new renewable energy capacity in the region. "This new solar facility will play an important role in our path to net-zero by 2050 or sooner," said Rupen Pandya, SaskPower President and CEO. "We are proud of our ongoing collaboration with Indigenous peoples and the critical role they are playing in the successful expansion of renewable energy in our province." GSI is one of four renewable energy subsidiaries of Libra Group, a privately owned, global business group that encompasses 20 businesses in six sectors, including renewable energy, maritime, aerospace and more. The Group's renewable energy portfolio encompasses approximately 3.5 gigawatts (GW) of projects owned, developed, or pending development in 10 countries, including solar, wind, battery storage, and waste-to energy projects. This is the second partnership with an indigenous community led by a Libra Group subsidiary. "Libra Group is proud of this novel partnership, which has come together through shared values and a commitment to driving economic growth and positive outcomes for communities," said Libra Group's CEO Manos Kouligkas. "Sustainability is core to our global business, and we look forward to continuing to leverage synergies across our six sectors in 60 countries with agility and impact."
