Transmission Access Charges (TAC): A Massive Market Distortion That Harms Local Renewables and California Ratepayers

Topic : Net Energy Metering    Valuation, Analysis, BCA    
State : California    
Author : Katie Ramsey, Clean Coalition; Daryl Michalik, Dynamic Grid Council
Adoption Year : 2016
Transmission Access Charges (TAC) are fees designed to pay for the state’s transmission system, including operations and maintenance, amortization of capital, and return-on-equity. TAC add about $0.03 per kilowatt-hour (kWh) to the levelized cost of energy over a 20-year contract, which is about 30% of the wholesale value of energy in California. To align costs and benefits, TAC should only apply to energy that is delivered through the transmission system. Therefore, TAC should be calculated based on the metered Transmission Energy own flow as

Location Matters: California Regulators Investigate More Granular Solar Benefits
Friday, October 21, 2016
Resource Type : News Article
Topic : Policy Positions    
State : California    
Author : Joseph Bebon
Adoption Year : 2016
In a transmission plan approved in March, the California Independent System Operator cancelled 13 subtransmission projects that previously had been approved in Pacific Gas & Electric (PG&E) territory. PG&E supported the project cancellations, which will save customers $192 million. The utility pointed out that rooftop solar and energy efficiency have reduced their load forecast and stated, “The need for those is just not there anymore.”

From the Executive Summary: To stimulate renewable energy development, governments at the local, state and federal level have provided a myriad of incentives for residential electricity customers who install solar panels on their roofs, some of which overlap. The combined effect of these incentives is quite substantial – particularly in light of the dramatic decline in the cost of solar panels that has recently occurred. This report aims to inform policymakers by quantifying the total incentives as a percentage of the installed cost of a ty

NEM is an electricity tariff billing mechanism designed to facilitate the installation of renewable customer distributed generation (DG). Under NEM tariffs, customers receive a bill credit for generation that is exported to the electric grid during times when it is not serving onsite load. Bill credits for the excess generation are applied to a customer’s bill at the same retail rate (including generation, distribution, and transmission components) that the customer would have paid for energy consumption, according to their otherwise applicable

We estimate the long-run economic value of variable renewable generation with increasing penetration using a unique investment and dispatch model that captures long-run investment decisions while also incorporating detailed operational constraints and hourly time resolution over a full year. High time resolution and the incorporation of operational constraints are important for estimating the economic value of variable generation, as is the use of a modeling framework that accommodates new investment decisions. The model is herein applied with

Though net metering has played an important role in jump-starting the PV market in the U.S., challenges to net metering policies have emerged in a number of states and contexts, and alternative compensation methods are under consideration. Moreover, one inherent feature of net metering is that the value of the utility bill savings it provides to customers with PV depends heavily on the structure of the underlying retail electricity rate, as well as on the characteristics of the customer and PV system. Consequently, the bill-savings value of net

In California, a Campaign to Take Transmission Charges Out of Distributed Energy

Author : Jeff St. John
Adoption Year : 2015
This article tackles the question why DERs in California are paying for access to a transmission grid if they don't use it? Under California's current transmission access charge (TAC), 3 cents per kilowatt-hour is added to the 20-year leveled cost of energy in the state to pay for transmission projects. The state's big IOUs base their TAC on the total amount of power consumed at their customer's meter, which means that the TAC does not take into consideration how distributed energy reduces the need for new transmission investments.

The economic value of distributed photovoltaic (PV) electricity is affected both by its correlation with transmission level energy prices and by a host of effects it may have on distribution systems. In this study we combine detailed physical simulation of distribution circuits with budgetary information provided by Pacific Gas & Electric (PG&E) to estimate PV's value with respect avoided transmission-level energy expenditures, avoided distribution system capacity upgrades, and increased expenditures to manage voltage magnitudes. We find that f

Abstract: Although residential solar photo-voltaic (PV) installations have proliferated, PV systems on some U.S. homes still receive no value during an appraisal because comparable home sales are lacking. To value residential PV, some previous studies have employed paired-sales appraisal methods to analyze large samples. Our first-of-its-kind study connects the two approaches. It uses appraisal methods to evaluate sale price premiums for owned PV systems on single-unit detached houses that were also evaluated in a large statistical study. Indep

This report reviews a recent sample of U.S. load-serving entity (LSE) planning studies and procurement processes to identify how current practices reflect the drivers of solar’s economic value. In particular, it analyzes the LSE’s treatment of the capacity value, energy value, and integration costs of solar energy; the transmission and distribution system, and options that might mitigate solar variability and uncertainty; the methods LSEs use to design candidate portfolios of resources for evaluation within the studies; and the approaches LSEs
