Prospex, Warrego Kick Off Solar Generation Project At El Romeral

Prospex, Warrego Kick Off Solar Generation Project At El Romeral
Prospex Energy and Warrego Energy have started the first of two solar diversification projects at the El Romeral power plant in Spain.

Prospex Energy and Warrego Energy have commenced the first of two projects in solar generation diversification at the El Romeral power plant in southern Spain.

The company holds a 49.9 percent working interest in El Romeral through its interest in Tarba Energía S.L. The remaining 50.1 percent working interest is owned by Warrego Energy Limited. 

Installation work to place solar panels on the roof of the power plant – Project Apollo – was approved by Tarba earlier this month and is expected to be completed by the end of July. Project Helios, the second solar generation project, involves the installation of photo-voltaic panels on land adjacent to the plant.  Front-end engineering and design (FEED) studies for Project Helios were approved by Tarba earlier this year and have now commenced.

El Romeral continues to provide a very healthy income from selling electricity on the spot market in Spain. Following the gas price cap instituted by the Spanish government as of mid-June, daily electricity prices are expected to average $158.4/MWhr for the coming 12 months. The El Romeral power plant is now operating 24 hours a day seven days a week as its default operating mode, thereby optimizing revenue.

Project Apollo consists of the installation of solar panels on the roof of the El Romeral power plant which will result in increased sales of electricity. Cost of installation is less than $52,000 and has been financed from existing funds held by Tarba. Payback from this investment is estimated to be approximately four years.

Installation of a total of 83 photo-voltaic panels in three separate zones on the power plant roof giving a total installed peak capacity of 41.5 kWh. With the sunny climate of Andalusia, this is expected to generate 66 MWh in the first year.

Energy generated from the photo-voltaic installation will feed the plant's ancillary services thus covering part of the plant's electricity demand during daylight hours allowing increased electricity sales.

Project Helios FEED studies to evaluate the options to install solar panels adjacent to El Romeral have been awarded to two local contractors. This will include the total cost and schedule including the permissions and permitting required.

Subject to further definition from the FEED studies, the capacity of Project Helios is expected to be in the region of 5 MW. Cost of FEED studies is $52,806 which is also being financed from funds held by Tarba. The total cost of Project Helios is being defined but is expected to be covered by future cash flows from El Romeral augmented by project finance.

Tarba is currently assessing land options and undertaking an initial environmental assessment

Both solar projects take full advantage of the existing connection to the power grid at El Romeral which has ample capacity to take the increased generation output.

“We identified the opportunity for solar co-generation last year, so it is extremely satisfying to be proceeding with these two projects which increase the sale of electricity and boost the ESG credentials of Tarba and its owners, both Prospex and Warrego.

“The installation of solar panels on the roof of the El Romeral power plant is a very fast and cost-effective way to increase our income at the plant whilst we await the approvals to drill further wells on the El Romeral production concessions. The installation of a solar farm adjacent to the plant will take longer and will be of greater scale but indications are that it will be value accretive and will enjoy short payback, made easier because of the existing grid connection and ample export capacity at El Romeral.

“Since the gas available from the producing wells on the El Romeral concessions allows just one of the three generators to be active at a time, the plant is at just 30 percent of capacity.  Receiving the permits to drill just two of the many identified structures on the existing concessions can take the capacity of the plant back to 100 percent of its design capacity,” said Mark Routh, Prospex’s CEO.
