NI Water AIR: Depreciation Charges by Asset Type 2019-2020

2019 and 2020 data from Northern Ireland Water's Annual Information Return details depreciation charges categorized by asset type under historic cost accounting. The dataset provides a financial breakdown of asset depreciation for a public water utility. It is available under an open government license and is hosted on multiple government data platforms.

Use Cases

• Analyzing the composition of depreciation expenses for a water utility based on asset categories.
• Benchmarking financial performance of public utilities using standardized Annual Information Return (AIR) metrics.
• Studying the application of historic cost accounting principles in regulated infrastructure industries.

Strengths

• Covers a specific two-year period (2019-2020) for consistent temporal analysis.
