Calculate the average electric power consumption in African countries with power stations capacity above 1000MW
Exact submitted task and declared adaptations
Calculate the average electric power consumption in African countries with power stations capacity above 1000MW

Task conventions: Use CONTINENT=Africa on supplied countries. A qualifying country strictly contains at least one supplied power-station point whose DsgAttr02 capacity is strictly greater than 1000 MW. Use the original country polygon, not a clipped boundary; no operating-status restriction. Calculate the unweighted mean of 2014 WDI EG.USE.ELEC.KH.PC values (kWh per capita) for qualifying countries with known data, one observation per country, not one per station. 2014 is the latest populated year in the frozen table. Join by ISO_A3/Country Code; missing values remain unknown. Maps are optional.

Some supplied power-station records lack geometry. They cannot satisfy a spatial relationship; do not assign them using a country-name guess. Disclose this coverage limitation and add unlocated_count to the final JSON: the number of capacity-above-1000MW station records without a usable location. The country selection and mean describe located qualifying records only.

Produce an inspectable contributing-country artifact with 2014 consumption, original geometry and benchmark_row_id. End with one fenced JSON object: {count: contributing countries with known consumption, unknown_count: qualifying countries missing consumption, coverage_note: string, selection: {collectionId, itemId, assetKey}, metrics: {mean: number}, value_field: name_of_consumption_column_in_selection}. Explain the average and units in prose.

Delivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs. This replaces the JSON-code-block formatting requirement above. Blue attaches your explicit selection to the accepted final answer. Finish with a concise ordinary-language answer agreeing with that selected result; do not duplicate the JSON in chat.

Recorded final answer

The average is **1,030.8 kWh per person in 2014** across **11** qualifying African countries. Important limit: this uses only countries that strictly contain a supplied **>1000 MW** station point. **Two located stations** above 1000 MW fell outside the supplied African country polygons, so they were excluded. **No high-capacity station records were unlocated**. ### Limitations - The country selection is based on supplied >1000 MW station points that are strictly within the supplied original African country polygons. - Two located >1000 MW station points did not fall within any supplied African country polygon and were excluded from qualification. - All 11 qualifying countries had known 2014 WDI values, so unknown_count is 0 and the mean uses 11 country observations. - Located qualifying records only. Two located >1000 MW station points did not fall within any supplied African country polygon and were excluded from qualification. - The result uses the supplied frozen World Bank WDI 2014 values, so it is a 2014 benchmark rather than a current-year average. - Qualification uses the supplied original country polygons, not clipped boundaries. - Country qualification is based on geometry only, not the station Country text field. - The result uses the supplied frozen 2014 WDI table only. - This is a country-level unweighted average, as requested.

Recorded investigation findings

The agent's reported hypotheses and assessments, retained as evidence of its process—not independent proof that the answer is correct. Failed calls retain their requested verdict, not an accepted assessment.

run_trial · failed

Do the supplied African country polygons, >1000 MW power-station points, and 2014 WDI table produce the required qualifying-country selection and unweighted mean, with unmatched high-capacity stations explained by records lacking usable location?

run_trial · completed

Do the supplied African country polygons, >1000 MW power-station points, and 2014 WDI table produce the required qualifying-country selection and unweighted mean, with unmatched high-capacity stations explained by records lacking usable location?

assess_trial · completed · assessment: sufficient

The full-scope trial answered the question. Filtering the supplied country polygons by CONTINENT=Africa produced 52 African country polygons. Filtering supplied power-station records by DsgAttr02 > 1000 MW produced 47 records, and all 47 had usable latitude and longitude, so unlocated_count is 0. A strict within join from stations to the original African country polygons matched 45 of those 47 located stations; 2 located stations did not fall within any supplied African country polygon. Counting located matches by country yielded 11 qualifying countries. Joining WDI by ISO_A3 to Country Code added the 2014 field, and all 11 qualifying countries had known 2014 consumption values. Table statistics on the qualifying-country artifact returned qualifying_count=11, known_count=11, and mean_2014=1030.801318579208 kWh per capita.

assess_result · failed · requested assessment: sufficient

I selected the inspected contributing-country artifact with 11 countries, original geometry and benchmark_row_id. The unweighted mean of 2014 WDI EG.USE.ELEC.KH.PC across those 11 qualifying countries is 1030.801318579208 kWh per capita. qualifying_count is 11, known_count is 11, and unknown_count is 0. All 47 supplied >1000 MW station records had usable coordinates, so unlocated_count is 0. A strict within join matched 45 of those located points to supplied African country polygons; 2 located points did not fall within any supplied African country polygon and were excluded from qualification.

assess_result · completed · assessment: sufficient

The published final outputs confirm the result. The selected contributing-country artifact contains 11 qualifying African countries with original geometry, benchmark_row_id and 2014 WDI electric power consumption per capita. The published summary table reports qualifying_count=11, known_count=11 and mean_2014=1030.801318579208 kWh per capita. The published >1000 MW station count table reports 47 records, and the published located >1000 MW station count table also reports 47 records, so unlocated_count is 0. The published station-country coverage check shows 2 located >1000 MW station points with ISO_A3 null after the strict within join, so those 2 points did not fall within any supplied African country polygon and were excluded from qualification.

  19. Progress update

    I’ve got a candidate method. I’m running one full private test now to check four things at once: the Africa filter, the strict point-in-country selection, the 2014 WDI join, and whether unmatched >1000 MW stations are just the unlocated records.

  20. Progress update

    The first trial call had a schema mistake in the request wrapper. I’m correcting that and rerunning the same test now.

  24. Progress update

    The trial is blocked only because the saved brief used the same CRS label issue. I’m correcting the brief’s explicit Africa study extent and then rerunning the test.

    The private test worked. I confirmed 11 qualifying countries, all 11 with known 2014 consumption, and a mean of about 1,030.8 kWh per person. I still need one final published artifact, and I’m checking the two unmatched located stations before I lock the coverage note.
