The premier's office says Redford is to speak about the effect of rapidly falling resource revenues on Alberta’s long-term economic plan.
Her eight-minute speech is to be broadcast on CTV stations Thursday night across the province.
Redford's Progressive Conservative government is to table its budget March 7.
The premier has suggested Albertans will face a tough budget, but no tax or fee increases.
In a letter to party members, Redford said her government will continue spending money on key infrastructure projects.
"As Progressive Conservatives, you gave our government a clear mandate to keep investing in services that support our families and our communities," Redford wrote in the letter released Wednesday.
"You told us to continue building the new roads, schools and health facilities we need. And we are listening."
She also said her government will hold the line on spending and live within its means.
Finance Minister Doug Horner has said soft oil prices are costing the province about $75 million per day in revenue.
