Facilitated by transmission planning, geographic and technological diversity of the generation fleet may provide a mitigation to capacity shortfalls. In this work, offshore wind (OSW) energy is sited in the areas off the West Coast between Coos Bay, Oregon, and Crescent City, California. Three generation and transmission scenarios are modeled within the Western Interconnection: (i) 3.4 gigawatts (GW) of installed OSW capacity connected to Southern Oregon through a High Voltage Alternating Current (HVAC) Radial Topology in 2030; (ii) 12.9 GW of installed OSW capacity connected to Washington, Oregon, and California through a High Voltage Direct Current (HVDC) Radial Topology post-2030, and (iii) the same 12.9 GW connected to the same locations through a Multi-terminal DC (MTDC) Backbone Topology post-2030. Zonal dispatch simulations assuming coincident wind, solar, and hydropower production and loads over 18 meteorological years, accounting for temperature-dependent equipment derating and forced outages, serve as inputs to the Associated System Capacity Contribution (ASCC) methodology. The capacity credit is 33%, 25% and 34% for the 2030 HVAC Radial Topology, 2030+ HVDC Radial Topology, and 2030+ MTDC Backbone Topology, respectively. Transmission design is shown to mitigate the typical erosion of marginal capacity contribution as more OSW is developed, underscoring the opportunity for grid modernization while decarbonizing the generation mix.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 4","pages":"Article 107407"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000423/pdfft?md5=3934a8bd352897e913d37ecf7bcb4f82&pid=1-s2.0-S1040619024000423-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141051010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We calculate the cost and effectiveness of four different clean energy procurement strategies: U.S.-wide annual energy matching, local annual energy matching, hourly energy matching, and carbon matching. Carbon matching requires balancing emissions attributable to electricity load with avoided emissions from clean energy procurement (calculated with locational marginal emission rates), while energy matching requires balancing load and clean energy generation on an annual or hourly timescale. We evaluated these strategies as pursued by large electricity consumers with two different load profiles located in five different U.S. regions which vary in regulatory structure. We find that carbon matching is the most cost-effective procurement strategy, with a cost between $4.7 and $7.6/MWh, and has the lowest carbon emissions abatement cost at $13/t CO<sub>2</sub> displaced. We find that annual energy matching costs range from $10/MWh to $32/MWh, and that it does not guarantee carbon neutrality. Hourly energy matching costs are higher, ranging from $68/MWh to $181/MWh, depending on region and load profile, and it is the least cost-effective strategy at carbon emissions reduction, with abatement costs ranging from $77/t CO<sub>2</sub> to $161/t CO<sub>2</sub>. These results suggest that targeting clean energy investment in regions where current renewable energy penetration is low and marginal emissions rates are high is the most effective way for individual actors to reduce Scope 2 carbon emissions and reach carbon neutrality.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 3","pages":"Article 107383"},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000186/pdfft?md5=6d7eab82800dc497816a639a4bba4a80&pid=1-s2.0-S1040619024000186-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140160063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electric power can be troublesome to appraise because consumption is not the customer’s main goal, but rather a means to achieve a desired good or service that often has unquantifiable personal value. This paper proposes a market-based household production method that quantifies the customer electric service interruption costs in the residential sector. Because an individual’s personal time is necessary to replace services owing to the lack of electric power, we propose a method that estimates the weighted market cost of a person’s time in accordance with their occupation to better calculate customer outage costs. We also present a macroeconomic production method to estimate losses in the residential sector. Finally, we propose a method for calculating the true costs of electric services by factoring the outage costs with the electrical utility rate to be analyzed using reliability metrics. The proposed approach facilitates a closer estimation of the low-bound true costs of utility-supplied electrical services for consumers who have not taken mitigation measures, serving as a warning for energy regulators to impose corrective actions or appropriate penalties on unreliable utilities and/or as an indicator for customers to invest in alternative energy sources.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 3","pages":"Article 107386"},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140052083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obstacles lie in the way of such a vision, however. Chief among them, paradoxically, is the administrative system that has evolved since the late 1990 s to promote regional electricity markets. That system abstracts from investment risk and the nation’s uneven geography of renewable resources. It lodges a kind of monopoly planning and scheduling power in a small group of bureaucratic centralized system operators that mimics a command economy in their own distinct regions, not the kind of market economy that has traditionally driven investment in US interstate energy infrastructure. And yet, in dealing with the vexing transmission constraints faced by the renewable generating sector (the “queue”), the Federal Energy Regulatory Commission (FERC) continues to pursue ever greater authority for those regional transmission organizations (RTOs). Such FERC action regarding its RTOs in 2022–23 represents a highly evident case of <em>path dependency</em>—a problem—that state or federal policy makers wishing to speed the entry of large-scale renewable generation, and complementary storage technologies, will have find a way either to confront directly or to work around.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 3","pages":"Article 107384"},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140016317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the rapid expansion of short-term storage options such as batteries, flexible resources such as existing hydroelectric reservoir storage are often overlooked. Using a capacity expansion and dispatch model of the Northeastern North American power system, we draw lessons from the interconnection potential of Quebec’s large existing hydropower capacities. We find that reservoir-transmission coupling significantly decreases the cost of decarbonization, even when short-term storage costs are low, because it is used for both daily and seasonal balancing. Conversely, the value of short-term storage is compromised by the availability of reservoir-transmission coupling, even assuming high investment costs for transmission. We also describe the regional distribution of costs and benefits of storage and transmission and discuss implications for regional cooperation.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 2","pages":"Article 107375"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000101/pdfft?md5=db9e24f8c07742257154a6628a3fa116&pid=1-s2.0-S1040619024000101-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140062961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
