Abstract
Our study conducts an innovative analysis of the power grid from a network perspective, shedding light on crucial aspects of the wholesale electricity market in Texas. By employing a power system engineering model, we construct a transmission network representation, presenting a novel contribution to the economics literature. Through our analysis of the network matrix, we delve into the characteristics of the Texas power grid, specifically focusing on the structural changes resulting from the Competitive Renewable Energy Zone (CREZ) project and their impacts on nodal prices. The empirical analysis provides additional evidence that ignoring changes in the transmission grid leads to biased estimates of various coefficients. This includes the spatial dependence coefficient, as well as the coefficients associated with control variables such as wind production and load. These empirical findings underscore the significance and distinctive value of network analysis in studying power grids.

期刊介绍：
The Electricity Journal is the leading journal in electric power policy. The journal deals primarily with fuel diversity and the energy mix needed for optimal energy market performance, and therefore covers the full spectrum of energy, from coal, nuclear, natural gas and oil, to renewable energy sources including hydro, solar, geothermal and wind power. Recently, the journal has been publishing in emerging areas including energy storage, microgrid strategies, dynamic pricing, cyber security, climate change, cap and trade, distributed generation, net metering, transmission and generation market dynamics. The Electricity Journal aims to bring together the most thoughtful and influential thinkers globally from across industry, practitioners, government, policymakers and academia. The Editorial Advisory Board is comprised of electric industry thought leaders who have served as regulators, consultants, litigators, and market advocates. Their collective experience helps ensure that the most relevant and thought-provoking issues are presented to our readers, and helps navigate the emerging shape and design of the electricity/energy industry.
