Thank you, Madam Chair. Comparing the actuals to the 2020-2021 Main Estimates, you will see that there was an increase in the actuals in 2019-2020 compared to budget. The reason for that is that we continue to work closely with all the hamlets, community governments. Through a review that we undertook, actually started a couple of years ago, but working with the communities, there were a number of invoices, actually, that were identified that were not submitted. There was a catch-up adjustment in 2019-2020, and we consider that to be a one-time. Going forward, you'll start to see that total expenditure going down to the current budget.
Now, previously, looking historically, the power bill of the Housing Corporation actually was quite a bit higher. It was about $1.5 million higher, I believe, a few years ago. The Housing Corporation does continue to work closely with our tenants to provide support and education in terms of energy efficiency. We've also, over the last few years, have adjusted the power rates to equate to residential rates, and that was an initiative to support self-sufficiency. It also brought with it a number of benefits. The power consumption compared to a few years ago has dropped quite a bit. It's about 10 to 20 percent, actually, in some areas where we have seen the consumption drop, so it's certainly supporting on the greenhouse gas emissions front.
Through that education piece that I mentioned, we will continue to work closely with our tenants and work with our partners, Arctic Energy Alliance, as an example, to continue to support our tenants in our energy efficiency practices. The Housing Corporation, in terms of our power, it was mentioned previously that we do continue to invest a significant portion of our available resources into both modernization and improvement projects. We have done some case studies, and we found that post a renovation, a major renovation, we have seen our utility costs drop up to 30 percent. There are certainly some benefits coming from those, as well. We will continue to closely monitor these utilities and bring forward those investments as we move forward. Thank you, Madam Chair.
