PV Magazine: RE+Storage Better Than a Colorado Utility’s Proposed 400 MW Gas Unit: Strategen

Posted by William Driscoll on Nov 16, 2023

PV Magazine reports on a recent analysis of the electric resource plan for Xcel Energy’s Colorado subsidiary, the Public Service Company of Colorado. The analysis, commissioned by Advanced Energy United and authored by Strategen Consulting Group, found a clean energy resource portfolio would be a more cost-effective way to power Colorado homes and businesses compared to building a new natural gas “peaker” plant. The article quotes United's Brian Turner, who speaks to the cost impact Xcel's proposed plant would have on ratepayers.
 

Storage and renewables projects already offered in response to an RFP from the Public Service Company of Colorado (PSCo) would be more economic and provide greater capacity than a 400 MW gas peaker unit proposed by the utility, found the consulting firm Strategen in an analysis of the utility’s proposed resource plan.

The Colorado utility, an Xcel Energy subsidiary, “takes commendable strides toward decarbonization,” says the Strategen analysis, but the low cost of clean energy resources supported by the Inflation Reduction Act “could provide an opportunity to avoid additional natural gas deployment.”

Strategen analyzed a portfolio of battery storage, solar and wind projects it selected from a public list of almost 800 bids for new renewables and battery projects that were offered in response to the utility’s 2022 all-source request for proposals.

Strategen said its portfolio, sized to exceed the capacity of a 400 MW gas peaker unit the utility proposed in its resource plan, would provide savings of about $29 million in its first year of operation, with greater savings in subsequent years. Those savings do not consider grid service benefits, stranded asset risk or fuel supply risk.

Because the costs for specific RFP bids are not publicly available, Strategen’s analysis assumed that the costs of the battery storage, solar and wind projects would equal the generic costs that PSCo presented in an appendix to its resource plan.

PSCo’s plan proposes 628 MW of new gas units by 2027, representing “long-term investments that will restrict PSCo’s ability to eventually achieve a fully decarbonized grid,” Strategen’s report says.

For two of the gas units proposed by PSCo—sized at 200 MW and 28 MW—Strategen was unable to analyze the potential to substitute renewables and storage because the utility proposed those units specifically for their local reliability benefits, and the public database of projects submitted in response to the RFP did not disclose location data. Strategen said its analysis of the 400 MW gas unit may also be applicable to the 200 MW unit if locational data and local reliability analysis were made available to stakeholders.

Strategen credited PSCo with proposing in its resource plan an 80% reduction in carbon emissions from 2005 levels by 2030, retiring all coal plants in the process.

Even so, Brian Turner, a director at the trade group Advanced Energy United, which sponsored the Strategen analysis, said Xcel’s proposal to build the new gas units “is a missed opportunity to provide Colorado households and businesses the best-cost and cleanest energy.” Turner noted that last winter the price of natural gas “skyrocketed, leaving ratepayers with high bills.”

Advanced Energy United said in a statement that as the cost of renewable energy continues to decline, new gas turbines risk becoming stranded assets, leaving ratepayers to pay billions of dollars “for a resource that may one day soon no longer produce any energy.”

The trade group formally presented its concerns in comments it submitted to the Colorado Public Utilities Commission.

Report: Xcel Energy’s proposed gas plant in Colorado is more expensive than clean energy options

Posted by Adam Winer on Nov 9, 2023

DENVER, CO – An analysis of the electric resource plan (ERP) for Xcel Energy’s Colorado subsidiary, the Public Service Company of Colorado (PSCo), found that a portfolio of clean energy resources – including solar, wind, and battery storage – would be a more cost-effective way to power Colorado homes and businesses compared to building a new natural gas “peaker” plant. The independent report from Strategen Consulting found that a clean energy portfolio would provide $28.9 million in savings compared to a new gas plant in the first year of operation, with savings in subsequent years anticipated to be even greater.

E&E News: How California Can Meets its 'Eye-Popping' Transmission Needs

Posted by Jason Plautz on Apr 19, 2023

PoliticoPro highlights the path forward for California to meet its transmissions needs, quoting Brian Turner on tightening coordination amongst agencies to address electrification and demand growth.

California will need to add more than $9 billion worth of new transmission infrastructure to avoid blackouts while also meeting clean energy goals, according to a new report from the state’s main grid operator. The draft report released last week by the California Independent System Operator identifies 46 new transmission lines needed to connect renewable energy projects to areas where people live.

Utility Dive: Amid High Energy Prices, SCE VP, Other Experts Push to Reduce California’s Reliance on Natural Gas

Posted by Kavya Balaraman on Apr 10, 2023

Utility Dive highlights the importance of moving away from natural gas reliance in California, quoting Sarah Steinberg and Brian Turner on the importance of demand-side management, batteries, hydro storage, and more.

As California reels from the impact of high natural gas prices this winter – as well as the ripple effects on the electricity sector – some experts are urging policy-makers to focus on reducing the state’s dependence on natural gas in the first place.

Gas prices in the West touched their highest annual point in the second half of December and began to subside in January, although still at a relatively high level. CAISO pointed to several reasons for that in its recent report: colder than usual temperatures in the West and Canada pushed up gas demand; there were lower gas storage inventories than usual – in part because of the higher gas usage during the heatwave California experienced last summer; as well as California’s lack of local gas supply and position at the end of the interstate pipeline system. 

Demand-side management is one of the best short-term policies that policymakers and consumers have at their fingertips to mitigate the impact of gas and electricity price swings, according to Brian Turner, policy director, Western states, with Advanced Energy United. This can include adjusting electricity use through consumer behavior, but also using advanced energy devices.
