Hydro One Limited is an electricity transmission and distribution utility serving the Canadian province of Ontario. It is the largest electricity transmission and distribution service provider in Ontario, distributing electricity to nearly 1.4 million customers. The utility works with the transmission and distribution network by connecting generating facilities operated by Ontario Power Generation, Bruce Power and several other privately-owned companies. The generators produce and deliver electricity from their hydroelectric, natural gas, wind, solar and nuclear facilities to businesses and households across Ontario.

In November 2015, Hydro One Limited became a publicly traded company on Toronto Stock Exchange. Its wholly-owned subsidiary Hydro One Inc. has CAD$12.445 billion of outstanding bonds as of April 2020.

Hydro One’s Challenges

Hydro One had several challenges when it came to monitoring its credit spreads and those of its peers in order to issue bonds in the most cost effective manner. These pain points included:

1. Large amounts of fragmented new issue and secondary spread data from many dealers submitted in various formats that required manual preprocessing
2. Numerous data sources across e-mails in various formats, often without a “consolidated” view option
3. Manual processing required for timely benchmarking. This task was challenging due to intra- day capital market movements, especially during times of heightened market volatility
4. Processing times that engaged personnel and system resources

By working with the Overbond Treasury Debt Capital Service and automating its data intake and analytics, Hydro One can now identify opportunities to reduce the cost of funding faster and more efficiently. In short, “price tension” in markets, benchmarks, historical data and investor sentiment can now be identified more quickly.

How Hydro One Outgrew Its Legacy Processes

Hydro One started uploading data in August 2019. At that time, the utility’s five-person treasury team was looking to improve the overall efficiency of its processes. They were experiencing information volume processing challenges and were looking for new methods to analyze fixed income markets and optimize interest costs. Hydro One was using Microsoft Excel to consolidate data and issuing bonds in Canadian dollars (CAD).

The treasury team had several key challenges to consider:

1. They needed to compare credit spreads with other regulated utilities/peers such as 407 International, Altalink, CU, Enbridge Gas and Toronto Hydro.
2. Hydro One had $1.15 billion in debt maturities in the next twelve months and typically issues $1.0 to $1.5 billion in long-term debt per year.
3. Optimal and efficient pricing in the debt capital markets was very important as the utility projected capital expenditures on its transmission and distribution business of approximately $10 billion over the next five years. These expenditures would need to be funded in part by new debt issuance.

Immediate Benefits

Hydro One was first introduced to the Overbond Treasury Operations module in mid-2019 and saw immediate improvements in its capital markets data management, which freed up time for its treasury team to focus on capitalizing on market opportunities and corporate initiatives. Two major benefits the treasury team realized through the process were:

1. Improved pricing data for new bond issues: insightful data aggregation and sector peer comparison with predictive capabilities

2. Reduced financing risks: reduction in risk of data entry errors through automation

Going forward, Hydro One will be looking to incorporate Overbond’s COBI Liquidity scoring feature to strengthen understanding of the liquidity of their own bonds as well as their peers’ bonds in the secondary market surveillance capabilities. The COBI Liquidity module utilizes metrics such as bid-ask spreads, trade count and volume, and intraday price volatility for the wide spectrum of bonds to derive a daily liquidity score for each bond

Inside the Hydro One – Overbond Portal

Overbond was able to deploy its AI-powered solution to help Hydro One aggregate data across various market vendors and data sources as well as dealer supplied runs. Overbond’s models structured, cleansed and processed voluminous data and mapped the data to the Reference Master. Subsequently, various AI-powered pricing algorithms operated on the reference master to output all modeled benchmarks and generated automated reports on a scheduled basis.
