Thank you, Doran, and good morning, everyone. We appreciate you joining us today to discuss our first quarter results. We are positive about our long-term growth potential despite challenges we experienced during this first quarter. We have record capital investment opportunities at our Utility and Pipeline businesses, a refinery that is now in production, and clear momentum at our construction materials business as well, along with increasing bidding opportunities at our construction service business with a combined backlog between both construction materials and services now approaching $1 billion.
Several factors negatively affected our results for this quarter. Some of the warmest winter weather on record affected utility earnings by approximately $6.6 million. Although the pipeline group did benefit from last year's rate case, the company incurred higher start-up costs for our Dakota Prairie Refinery as the time neared to commencing operations impacting this year's first quarter by about $1.9 million.
The construction services group sold underperforming nonstrategic assets in the first quarter, recording an expense of $1.4 million. And our construction materials group had a true-up of a multi-employer pension plan withdraw liability of $1.5 million related to the same plan for which an estimate was recorded in the fourth quarter of 2014. These items on a combined basis totaled $11.4 million or $0.06 per share of a negative impact to the first quarter earnings compared with last year. So including these items, consolidated adjusted earnings for the first quarter totaled $22.8 million or $0.12 per share compared with $35.6 million or $0.19 per share in 2014. On a consolidated GAAP basis, which includes our Exploration and Production business, we reported a loss of $306.1 million or $1.57 per share, reflecting a $315.3 million after-tax noncash write-down of oil and natural gas properties pertaining to the quarterly ceiling test.
Turning to business unit results and operational updates. Our utility businesses reported earnings of $29.8 million. Earnings were positively affected by the implementation of the environmental cost recovery rider and the electric generation resource recovery rider in North Dakota. And we continue to see strong current growth in the Bakken area with increases of 4.4% in electric customer counts and 3.6% in natural gas customers in the first quarter compared to a year ago. More than offsetting these items was significantly warmer winter weather across our service territory, resulting in a $6.6 million earnings effect with a natural gas sales decline of 14%, along with a slight decrease in electric sales. While we do have weather normalization in North Dakota, South Dakota and Oregon, we do not have weather -- natural gas weather normalization in our remaining 5 states of operation. Higher O&M costs, largely as a result of a planned outage at Big Stone generating plant, also impacted earnings quarter-over-quarter. Given the substantial growth in investment for our utility, timely regulatory recovery is a primary focus. We have pending natural gas rate increases cases in Wyoming, North Dakota, Oregon, and just last week, we received PSC approval for $2.5 million annually on our Montana gas case. We have filed in North Dakota for advanced determination of prudence for the Thunder Spirit Wind project as well as an update to the environmental cost recovery rider as well. We expect to file electric rate cases in Montana, South Dakota and Wyoming and natural gas cases in Washington, Minnesota and South Dakota, with most of these cases expected to be filed this year.
We continue to expect this business to grow substantially over time with the investment opportunities ahead. Rate base growth is projected at 11% compounded annually over the next 5 years, including plans for a record $1.8 billion gross capital investment program. New electric generation and transmission and electric and natural gas distribution investments are planned to serve the growing customer demand and to enhance reliability along with system integrity. Specifically, 3 projects to be completed this year include the $200 million Thunder Spirit Wind project to be built here in Western North Dakota; a $385 million upgrade to our Big Stone generating plant, of which our share is approximately $90 million; and the addition of 19 megawatts of natural gas-fired generation near our Lewis & Clark station in Sidney, Montana. In addition, we are working on a $340 million 345-kV transmission line that is a MISO multi-value project expected to be completed in 2019, with our share being 1/2. Our utility is really in a great position focused on timeliness of regulatory recovery along with our planned investment and executing on the substantial identified projects, as I just recently laid out.
Next, at our pipeline group, earnings were $4 million, including that $1.9 million after-tax increase in our portion of the start-up costs related to the refinery. Absent these costs, earnings would have been up $1.6 million or 33% quarter-over-quarter. This corresponds to transportation volumes, which were 30% higher, driven by strong growth of all system transportation volumes. Also benefiting earnings were increased rates from that favorable rate case settlement we had May of 2014.
Gathering and processing volumes also increased at our Pronghorn facility, but were largely offset by lower processing rates. And as we announced yesterday along with Calumet, our partner on the project, the Dakota Prairie Refinery, the first greenfield refinery built in the U.S. in nearly 40 years, has commenced operations. With more than 2/3 of North Dakota's diesel fuel currently imported into the state, the refinery is well positioned to meet strong regional demand with additionally -- and additionally, local-produced supplies of diesel fuel. We expect to begin sales of diesel fuel as the plant ramps up during the month of May.
Construction of the facility began just back in March 26, 2013, and it is located 4 miles west of Dickinson, North Dakota. We had more than 800 workers that were on-site at peak construction, and the plant was constructed with 0 lost time accidents over the 2.1 million man hours worked to build the facility. The facility is designed to process some 20,000 barrels per day of locally sourced Bakken crude. And the production slate includes up to 7,000 barrels per day of diesel, approximately 6,500 barrels per day of naphtha and about 6,000 barrels per day of atmospheric tower bottoms or ATBs. Naphtha will be used as a diluent to transport heavy oil by pipeline or as a feedstock in natural gas production. And ATBs can be used as feedstock for lubricating oils and other refined products as well.
We continue to project an EBITDA contribution for the first full year of operation of the refinery to be in the range of $60 million to $80 million, and this will be shared equally by our partner, Calumet.
As we look forward, we have a number of additional growth opportunities at our pipeline group that are included in our 5-year record capital expenditure program, which totals $1.1 billion. The $120 million Wind Ridge Pipeline project is a 95-mile natural gas pipeline designed to deliver approximately 90 million cubic feet per day off of Northern Border system and deliver it to near Spiritwood, North Dakota, where an announced fertilizer facility will be built. We're continuing work on acquiring easements as well as filing an application on the project. Potential really also exists for expansion of the pipeline to serve communities in growing markets in Eastern North Dakota. Our projected in-service date for the Wind Ridge project is in 2017.
In addition, our pipeline group has an agreement with an anchor shipper to construct a pipeline to connect the Demicks Lake gas processing plant in Northwestern North Dakota to deliver natural gas into a new interconnection with the Northern Border pipeline. Project costs are estimated to be in the $50 million to $60 million range.
And we're also continuing our evaluation of a potential development of a second diesel refinery here in North Dakota. We are encouraged by the growth potential we see for our pipeline group as it continues to pursue new opportunities and expansion of existing facilities and services offered to our customers.
Now I'd like to move on to our construction businesses. Here, we reported a combined loss of $9.8 million for the quarter. Our construction materials business had its best first quarter since 2007, narrowing our seasonal loss by 38% compared to the first quarter last year. Favorable weather was a positive for this business in the first quarter, allowing us to get out -- an earlier start on the construction season this year. We are pleased that our construction materials business is really gaining momentum. Trailing 12-month earnings net of the withdrawal liability recorded for that multi-employer pension plan is now at $70.3 million, up from annual earnings of $26.4 million just back in 2011, which was the low point during the great recession. Returns on capital have more than doubled over that time period as we continue trending with higher margins with that lower cost structure now in place. We have seen an increase in volumes of aggregate and asphalt sales up 26%. Ready mix concrete volume is up nearly 16%. However, levels are still at approximately only 60% of peak volumes, so we still have capacity to handle more work in our markets without requiring a significant amount of near-term capital. Backlog also continues to trend up, now at $664 million as of March 31. And the bidding environment continues to be strong, with incremental work being secured in a number of our markets.
At our construction service businesses, workloads declined in the first quarter compared to last year's all-time record quarterly earnings, largely as a result of the closing out of several stronger-margin large projects a year ago. And although we're seeing strong bidding opportunities, the timing of new project awards did not allow us to offset or replace those workloads.
First quarter also reflects a $1.4 million expense after-tax associated with the sale of certain nonstrategic and underperforming assets. Backlog is lower this year than the prior year. However, it is up from year-end. We are pursuing opportunities that we believe will be reflected in the backlog in workloads later this year. For example, we are a finalist on a substantial transmission project that is expected to be awarded within the next month. With regard to electric and mechanical work, we have been verbally awarded a sizable institutional project that we are pursuing, another with an expected award date later this year. We also have been awarded a preconstruction service phase on a project, with the construction phase expected to be awarded again later this year. And we are waiting contract award for another sizable project to be in construction in the second half of 2015.
Along with this, and on the industrial side, the level of maintenance work has increased, and we are in the planning stages on several larger projects for upcoming turnarounds. Overall, bidding opportunities are increasing with an improvement of securing [ph] work with actually better margins. There are pending project opportunities in all of our regions, and equipment sales and rentals do remain very strong. We believe these projects and others that are -- we're pursuing will have a significant positive impact to the backlog, revenue along with margin at construction services. With our lower cost structure, improving economies and our highly skilled operations teams in our construction group, we continue to be economic about the long-term growth for our construction businesses.
Now I'd like to move on to our Exploration and Production company, Fidelity. From an operational standpoint, we are living within cash flows and we have recently added some hedges to reduce that volatility of cash flows for the near term. Our focus on lowering the cost structure has resulted in a 15% reduction in lease operating expenses, and we plan to continue to pursue additional reductions.
Our general and administrative expenses has -- have also been reduced. We are moving forward with plans to maximize the value of reserves, with recent positive well results in both the Paradox along with East Texas. We are pleased with the production levels of our assets, noting the majority of our production decreases are due to prior year asset sales with some additional impact from lower capital levels. We certainly like the stability that we've seen in oil prices as of late, and we will pursue the marketing and sale of our E&P business as we determine appropriate.
So I'd like to wrap things up. As we continue to be excited about the future of MDU Resources Group, we have substantial investment opportunities that underlie our record $3.9 billion, 5-year capital investment program. We expect to fund our $755 million in planned gross capital expenditures for this year largely with cash flow from operations. Our balance sheet remains strong. Our credit ratings are solid at BBB+ stable, and our liquidity position from our various credit lines that back our low-cost commercial paper programs is extensive. And we have continued to track record -- and we have continued to track our record of paying dividends for now 77 straight years and increasing it for the past 24 years. We're only one of a handful of companies that can really say the same.
So I am confident that we're well positioned to produce significant long-term value as we execute on our business plans and the opportunities we have right in front of us for the benefit of our shareholders. I appreciate your interest and commitment to MDU Resources organization, and I'd certainly be happy to open up the lines to questions that you may have at this time. Operator?
