Dominion Energy Proposes New Solar and Energy Storage Projects in Virginia

Dominion-PV-and-Energy-Storage

By Power Engineering:

“Dominion Energy has proposed nearly two dozen new solar and energy storage projects, according to new filings with Virginia regulators. If approved by the Virginia State Corporation Commission (SCC), the projects will provide more than 800 MW of electricity.

Ten solar and storage projects totaling nearly 500 MW would be directly owned and operated by Dominion. The proposal also includes PPAs with 13 solar and storage projects, totaling more than 300 MW.

Construction of the projects is projected to support nearly 4,800 clean energy jobs and will generate more than $920 million in economic benefits across Virginia.”

AES Increases Its Battery Energy Storage by an Additional 908 Megawatt-hours in California

AES-Energy-Storage

By Renewable Energy World: AES confirmed two new future battery storage sites in Lancaster CA for a total of 227 MW / 908 MWh capacity. “The two facilities are expected to provide a boost to California’s grid, storing renewable energy to be dispatched during periods of high demand.”

AES is awarding contracts for both Clean Power Alliance and PG&E for purchasing the renewable energy from its Luna and Lancaster (LAB) facilities. “In its own announcement, Fluence said the LAB system will use its Mosaic platform for intelligent bidding in the state’s wholesale market, operated by CAISO. Mosaic will “integrate directly with Gridstack, processing operating constraints and parameters in real-time, and employ advanced machine learning and artificial intelligence to generate bids that maximize LAB’s market earnings.”

Xcel Energy Strengthens the Grid with Advanced SVCs

Static-VAR-Compensators

T&D World – Xcel Energy uses flexible static VAR compensator topology to adapt to changing network conditions in New Mexico for more stability and voltage control.

In 2010, Xcel Energy Inc. was tasked by Southwest Power Pool Inc. (SPP) to build out the transmission system in southeast New Mexico, U.S., because the oil and gas industry in the area had a growing need for electricity. Oil producers were asking to convert from expensive diesel to more affordable electricity for their pumps. The request from SPP consisted of a transmission system expansion of new 115-kV and 345-kV projects in the region. Spending had to be prioritized between 2010 and 2021 because of the sheer scale of the plan needed to successfully implement the request.

Xcel Energy addressed the plan by implementing projects classified as high priority. This plan resulted in initiating 44 new transmission projects, an investment of US$557 million. In 2016, two static VAR compensators (SVCs) — the China Draw and Roadrunner — were built in southeast New Mexico to support SPP’s request.

To build or not to build: TVA asks public to weigh in on construction of large solar farm

TVA-PV-Solar-Farm

RenewableEnergyWorld – The Tennessee Valley Authority (TVA) is asking for public input on the draft Environmental Impact Statement for the North Alabama Utility-Scale Solar Project in Lawrence County.

In January 2019, TVA announced that it holds a two-year purchase option on 3,000 acres in Lawrence County to study the feasibility of building a large solar farm in order to continue reducing its carbon footprint.  

The purpose of this EIS is to address the potential environmental effects associated with constructing, operating, maintaining, and decommissioning the solar facility.

The draft EIS includes two alternatives: a No Action Alternative and an Action Alternative. Under the No Action Alternative, TVA would not execute the purchase under the Purchase Option Agreement, and TVA would not develop a solar facility at this location. Under the Action Alternative, TVA would execute the purchase under the Purchase Option Agreement for the Lawrence County, Alabama, property.
