It will pay an 8.45 cent interim dividend on April 18, up from 8.3 cents a year ago.
Genesis shares fell 1.1 per cent to $2.74, trimming their gain the past year to 17 per cent.
Earlier today, the company reported a 2 per cent decline in first-half operating earnings when an unusual combination of events late last year required greater coal-burn at the firm's dual-fuel Rankine units at Huntly but also reduced its gas-fired capability.
That, and reduced oil and gas production from the Kupe field it owns 46 per cent of, offset gains from improved pricing and volumes in its retail business.
Group ebitdaf fell to $196 million for the six months through December, from $198 million a year earlier. Net profit jumped to $49 million, from $28 million, on fair value adjustments and reduced depreciation charges. Underlying profit rose 4 per cent to $43 million.
Wholesale power prices surged in October and November as declining South Island hydro storage coincided with reduced gas supply from Pohokura and a five-week shut of the 400 MW E3p gas-fired plant Genesis operates at Huntly.
That combination lifted the firm's average generation price for the half-year to $146/MWh – 52 per cent higher than a year before – but production fell by 12 per cent.
As a result, ebitdaf from the firm's wholesale business fell to $104 million, from $106 million a year earlier. Trading earnings were boosted by $9 million, but that was more than offset by a $7 million impact from the E3p shut and $4 million of losses on the firm's market-making activities in the ASX futures market.
Chief executive Marc England said the losses on market-making – highest in September and December - were driven by the increased volatility during the period.
He said the ASX market is a vital risk management tool for the sector, but he favours a review of the current voluntary arrangements to ensure costs are shared fairly.
Reduced production from Kupe, reflecting the E3p shut, lower oil yields and the timing of shipments, saw ebitdaf from the firm's oil and gas arm fall to $53 million from $56 million a year earlier.
In the customer business, electricity sales were 4.4 percent higher at 3,139 GWh, largely due to greater volume being sold to commercial and industrial customers. Average prices were also higher. Gas and LPG volumes also improved, again boosted by sales to business and heavy industry.
That saw customer group ebitdaf climb by $6 million to $62 million. A $1 million reduction in residential gross margin was more than offset by lower operating costs, reduced bad debts, and improved earnings from the LPG operation and business sales.
England noted gross customer churn was down 4.8 percent and the number of customers taking multiple fuels was up 6.4 percent.
"Both outcomes show that investing in great service, innovative products and loyalty initiatives is right for Genesis," he said.
