Detailed project report solar power plant pdf download

At the end of 2021, there were at least 674 GW of utility-scale solar power capacity within the interconnection queues across the nation, 284 GW of which include batteries.

Our public data file tracks metadata and PPA prices from 67 PV+battery hybrid projects that are already online or that have secured offtake arrangements. Adding battery storage is one way to increase the value of solar.In 2021, solar’s average market value (defined in the report to include only energy and capacity value) rose by 55% to $47/MWh and exceeded average wholesale prices in 13 of the 17 balancing authorities analyzed.

Prices from a sample of recent contracts average around $20/MWh (levelized) in the West and $30-40/MWh elsewhere in the continental US.

PPA prices have largely followed the decline in solar’s LCOE over time, but have recently stagnated and even moved slightly higher.

Utility-scale PV’s LCOE fell to $33/MWh in 2021 ($27/MWh if factoring in the federal investment tax credit, or ITC).

The report explores drivers of this variation.

Project-level capacity factors vary widely, from 9% to 35% (on an AC basis), with a sample median of 24%.

Median installed project costs declined to $1.35/W AC (or $1.02/W DC) in 2021.

90% of all new utility-scale PV capacity added in 2021 uses single-axis tracking.

A record of nearly 12.5 GW AC of new utility-scale PV capacity came online in 2021, bringing cumulative installed capacity to more than 51.3 GW AC across 44 states.

Key findings from this year’s report include: While focused on key developments in 2021, this report explores trends in deployment, technology, capital and operating costs, capacity factors, the levelized cost of solar energy (LCOE), power purchase agreement (PPA) prices, and wholesale market value. fleet of ground-mounted photovoltaic (PV), PV+battery, and concentrating solar-thermal power (CSP) plants with capacities exceeding 5 MW AC. Berkeley Lab’s “Utility-Scale Solar, 2022 Edition” presents analysis of empirical plant-level data from the U.S.
